FIG. 4 is a perspective view showing the battery 100 from diagonally above, and FIG. 5 is a perspective view showing the battery 100 from diagonally below. 4 and 5, for convenience of explanation, a virtual line V passing through the center of the battery 100 in a plan view and extending along the longitudinal direction of the battery 100 is shown as a two-dot chain line.
The battery 100 has an energy storage device such as a battery cell stored therein, and can also be called a power storage device. The battery 100 of this configuration is formed into a substantially rectangular parallelepiped shape having a pair of end surfaces 101 and 103 located at both longitudinal ends of the battery 100 and forming an upper surface and a lower surface, and four side surfaces 107.

A battery handle 102 that can be held by a user is provided on an end surface 101 constituting the top surface of the battery 100. The battery handle 102 is formed of a side handle portion 104 extending along one side of one end surface 101, and a center handle portion 106 extending from approximately the center in the longitudinal direction of the side handle portion 104 to the opposite side, It is formed into a substantially T-shape in plan view.
A battery terminal 108 is provided on an end surface 103 that constitutes the bottom surface of the battery 100. The battery terminal 108 is a female terminal that is provided at a position close to one side of the end surface 103 and extends along the side. The battery terminal 108 employs a terminal classified as a receptacle terminal or a female connector.

The side of the end surface 103 on which the battery terminal 108 is arranged close to each other overlaps the side of the end surface 101 on which the side handle portion 104 is provided in a plan view in the longitudinal direction of the battery 100. A projecting surface portion 105 that projects outward from the periphery of the end surface 103 is provided approximately at the center of the end surface 103 . The protruding surface portion 105 is formed into a substantially rectangular shape in plan view, and the protruding end is formed into a flat surface.

One battery side surface 109 corresponding to the back surface of the battery side surfaces 107 is formed into a curved surface that curves along a direction intersecting the longitudinal direction of the battery 100 when viewed from the longitudinal direction of the battery 100. . In contrast, the other battery side surface 107 is formed into a substantially flat surface. Therefore, the battery 100 is formed in a rotationally asymmetrical shape with the virtual line V as the rotation axis. The battery side surface 109 formed into a curved surface is continuous with the side of the end surface 103 where the battery terminal 108 is disposed close to the side of the end surface 101 where the side handle portion 104 is provided. Note that the battery 100 corresponds to an "electrical device" in the present disclosure.

As shown in FIG. 2, the housing mechanism 30 includes a battery case 32 that removably holds the battery 100, a case frame 50, a holding handle (also referred to as an operation lever or a lock lever) 62, and a locking mechanism 76. (see FIG. 3) and a case side connection terminal 54. The battery case 32 is a box-shaped case made of resin that conforms to the outer shape of the battery 100, and has an inlet/outlet 31 that communicates with the upper surface opening 13 and allows the battery 100 to be inserted or removed. The battery 100 is formed to have a rotationally asymmetric outer shape with the imaginary line V as the axis of rotation, and the battery case 32 is formed to match this outer shape. Battery 100 cannot be inserted into battery case 32. Therefore, the situation where the battery 100 is inserted into the battery case 32 in the wrong direction is avoided.

Furthermore, a starting battery 94 (see FIG. 2) is arranged between the battery case 32 and the left and right side panels 19. The starting battery 94 is a power storage device that supplies power to the processor that controls the housing device 1 and various electrical components. When the operator for starting the accommodation device 1 is operated, the activation battery 94 supplies power to the processor, and the processor starts controlling the accommodation device 1, thereby driving the accommodation device 1. Startup battery 94 provides power at a lower voltage than battery 100. The starting battery 94 of this configuration is attached to the battery case 32 via a fixing bracket 96 (see FIG. 2).

The case frame 50 is a frame-shaped member and is fixed to the upper part of the battery case 32. The case frame 50 is made of a material having higher strength than the battery case 32, for example, a metal material. The holding handle 62 is movable between a position corresponding to the upper part of the loading/unloading port 31 of the battery case 32 (hereinafter referred to as the lock position) and a position evacuated from the loading/unloading port 31 (hereinafter referred to as the unlocked position). , is attached to the battery case 32.

The locking mechanism 76 (see FIG. 3) is provided at the loading/unloading port 31 of the battery case 32, and has an opening/closing portion that opens and closes to restrict removal of the battery 100 from the loading/unloading port 31. The locking mechanism 76 of this configuration is interlocked with the movement of the holding handle 62, so that when the holding handle 62 moves to the lock position, it moves to the side that closes the loading/unloading port 31 and restricts the removal of the battery 100. When the holding handle 62 moves to the unlocked position, the locking mechanism 76 moves to the side where it is retracted from the loading/unloading port 31, and the battery 100 can be taken out.

Case-side connection terminal 54 is a terminal connected to battery terminal 108 of battery 100 in battery case 32 and is provided below battery case 32 . The case-side connection terminal 54 employs a terminal classified as a plug or a male connector.
In this configuration, the case side connection terminal 54 moves in conjunction with the movement of the holding handle 62, so that when the holding handle 62 moves to the lock position, it rises to the position where it connects to the battery terminal 108, and the holding handle 62 is unlocked. When moved to this position, it is lowered to a position where it is retracted from the battery terminal 108.

The battery case 32 corresponds to the "holding part" of the present disclosure, and the holding handle 62 corresponds to the "operation lever" of the present disclosure. Further, the battery terminal 108 corresponds to a "first terminal" in the present disclosure, and the case side connection terminal 54 corresponds to a "second terminal" in the present disclosure. In the following description, the battery terminal 108 will be referred to as a "first terminal 108," and the case-side connection terminal 54 will be referred to as a "second terminal 54." Further, the end surface 103 of the battery 100 will be referred to as "the bottom surface 103 of the battery 100."

6 is a perspective view showing the battery case 32 from diagonally above, FIG. 7 is a view showing the battery case 32 from above, and FIG. 8 is a view showing the battery case 32 from diagonally below.
The bottom plate 40 of the battery case 32 is a part that constitutes the lower part (inner part) of the battery case 32. The upper surface of this bottom plate 40 becomes a facing surface that faces the bottom surface 103 of the battery 100 when the battery 100 is housed in the battery case 32. In this configuration, the bottom plate 40 including the opposing surface is formed in substantially the same rectangular shape as the bottom surface 103 of the battery 100. Note that the shape of the bottom plate 40 including the facing surface may be changed as appropriate.

A terminal hole 41, a plurality of recesses 201, a plurality of connecting portions 211, a groove 221, and the like are formed on the opposing surface. The terminal hole 41 is a hole through which a terminal for electrically connecting the battery 100 and the housing device 1 passes, and is also referred to as a terminal hole. In this configuration, the second terminal 54 passes through the terminal hole 41. However, the configuration is not limited to this, and for example, if the battery terminal 108 is configured to protrude downward, or if the battery terminal 108 is configured to be moved downward, which is the second terminal 54 side, the terminal hole 41 may be configured such that the first terminal 108 passes therethrough.

The terminal hole 41 is provided at a position offset in the first direction α corresponding to the rear with respect to the center CP of the opposing surface (see FIG. 7). This terminal hole 41 is formed in the shape of a long hole extending in the left-right direction orthogonal to the first direction α.
As shown in FIG. 3, the second terminal 54 is attached to the lower part of the housing 10 at a position offset rearward (corresponding to the first direction α) from the center CP of the opposing surface, and the tip of the second terminal 54 is placed facing upwards. In this configuration, an interlocking mechanism that moves the second terminal 54 up and down in conjunction with the operation of the holding handle 62 is provided. This interlocking mechanism moves the second terminal 54 upward to pass through the terminal hole 41 when the holding handle 62 moves forward to the lock side (corresponding to the lock position). It is connected to the first terminal 108. Furthermore, when the holding handle 62 moves rearward to the unlock side (corresponding to the unlock position), the interlocking mechanism moves the second terminal 54 downward and separates it from the first terminal 108 .

As shown in FIGS. 6 and 7, the plurality of recesses 201 have a downwardly recessed shape. Each concave portion 201 is provided at a position corresponding to a leg (not shown) provided on the bottom surface 103 of the battery 100, and functions as an escape portion for escaping the leg. The concave portions 201 of this configuration are provided at positions approximately equally spaced apart from the center CP of the opposing surface, at positions corresponding to the four corners of the opposing surface, and at positions avoiding the terminal holes 41. . A communication hole 201H that penetrates in the vertical direction so as to communicate the inside and outside of the bottom plate 40 is provided at the center position of the lowest part of these recesses 201.

Further, the battery case 32 is provided with a slit-shaped communication hole 202H extending vertically from the bottom plate 40 to the lower part of the side surface 107. Furthermore, the plurality of connecting portions 211 are provided with communication holes 203H, which penetrate in the vertical direction so as to communicate the inside and outside of the bottom plate 40, at positions offset from the center. These communication holes 201H, 202H, and 203H communicate the inside and outside of the bottom plate 40, and function as drain holes for draining moisture and the like that have entered the battery case 32. Note that the positions and shapes of the recessed portion 201 and the communicating holes 201H, 202H, and 203H can be changed as appropriate.

The plurality of connecting parts 211 are provided at intervals in at least one of the front and rear and left and right directions, avoiding the areas of the terminal hole part 41 and the recessed part 201. These connecting parts 211 are formed into annular bosses through which connecting members (for example, screws) can be passed for connecting the bottom plate 40 of the battery case 32 and the panel-side bosses 29 (see FIG. 2) of the housing 10. has been done. In this configuration, as shown in FIG. 8, these connecting portions 211 are formed in a boss shape that protrudes downward from the bottom plate 40 of the battery case 32. Therefore, sufficient strength can be ensured at the connection point between the battery case 32 and the housing 10, and space for arranging parts such as wiring can be easily secured between the bottom plate 40 of the battery case 32 and the housing 10. .

As shown in FIG. 8, on the back surface of the bottom plate 40, protrusions 213 having a polygonal cross section are formed at intervals in the front, rear, left and right directions. These protrusions 213 function as reinforcing ribs that reinforce the bottom plate 40. In this configuration, each protrusion 213 is formed to have a hexagonal cross section, and by sharing each side with an adjacent protrusion 213, a so-called honeycomb structure is formed. In this configuration, substantially the entire area of the back surface of the bottom plate 40 excluding the connecting portion 211 is formed in a honeycomb structure.

Note that the number, shape, and range of the protrusions 213 may be changed as appropriate. For example, by applying a plurality of polygonal shapes that are adjacent to each other and share at least one side to the protrusion 213, the protrusion 213 can function as a reinforcing rib that effectively increases the strength of the bottom plate 40. . Further, the protrusion 213 may have a shape other than a polygon. Further, it is preferable that the shape of the protrusion 213 is different from the shape of the groove 221. Since the shape of the protruding portion 213 is different from the shape of the groove portion 221, it is possible to avoid a situation where locally thick portions continue in a straight line, and it becomes easier to suppress unevenness in the strength of the bottom plate 40.

The groove portion 221 is a portion having a groove extending along the surface of the opposing surface.
The groove portion 221 of this configuration includes a first groove portion 221A having a first groove M1 extending in the left-right direction. The left-right direction in which the first groove M1 extends corresponds to a direction perpendicular to the direction (first direction α) in which the terminal hole 41 is offset from the center CP of the opposing surface.
By providing the first groove 221A on the opposing surface, foreign matter such as sand attached to the bottom surface 103 of the battery 100 can be allowed to enter the first groove 221A. Therefore, it is possible to avoid a situation where a foreign object is caught between the bottom surface 103 and the opposing surface of the battery 100. Thereby, even if a foreign object enters the battery case 32, the battery 100 can be properly held. Moreover, since the first groove part 221A extends in a direction perpendicular to the rear (first direction α) where the terminal hole part 41 is offset from the center CP of the opposing surface, foreign matter that has entered the first groove part 221A can be removed from the terminal hole 41. It is possible to avoid the situation of movement toward the hole 41 side. With these, it is also possible to avoid a situation where foreign matter adheres to the first and second terminals 54 and interferes with the connection between the terminals.

The first groove portion 221A is provided over a region of the opposing surface that is forward of the terminal hole 41 (in the second direction that is opposite to the first direction α), so that the first groove portion 221A covers a half or more area of the opposing surface. It is set in. More specifically, the first groove portion 221A is provided in a region in front of the terminal hole portion 41 and in substantially the entire region sandwiched between the plurality of recesses 201 and the connecting portions 211.
The first groove portion 221A is composed of a plurality of first grooves M1 parallel to each other, and each first groove M1 extends over substantially the entire length of the opposing surface on the left and right sides. Since there are a plurality of first grooves M1, the area of the first grooves M1 is expanded, making it easier to trap foreign substances in the first grooves M1.

As shown in FIG. 7, the groove portion 221 further includes a second groove portion 221B having a second groove M2 extending in a direction intersecting the first groove M1. The second grooves M2 are provided at intervals in the left-right direction orthogonal to the front-rear direction in a region of the opposing surface that is forward (second direction) of the terminal hole 41. That is, the groove portion 221 of this configuration includes a first groove M1 corresponding to a horizontal groove extending in the left-right direction and a second groove M2 corresponding to a longitudinal groove extending in the front-rear direction. Foreign matter such as sand attached to the battery 100 can be captured by either of the grooves M1 and M2. Therefore, it is possible to avoid a situation where the battery 100 cannot be held properly or a situation where the terminal connection is affected by the foreign object.
Furthermore, since the bottom plate 40 of the battery case 32 is formed into a wave shape by the groove portion 221, the bottom plate 40 becomes difficult to bend, and the strength of the bottom plate 40 can also be improved. Further, neither the first groove portion 221A nor the second groove portion 221B is connected to the terminal hole portion 41. Therefore, foreign matter and moisture can be prevented from falling into the terminal holes 41 through the respective grooves 221A and 221B.

Next, the detailed structure including the periphery of the terminal hole 41 and the cross section of the groove 221 will be described.
FIG. 7 shows an enlarged view of the periphery of the terminal hole 41. As shown in FIG.
As shown in this figure, a peak 230 that projects upward extends at the boundary between the terminal hole 41 and the groove 221. Furthermore, a groove M1X extending parallel to the first groove M1 extends between the peak portion 230 and the second groove M2. Even if foreign matter or moisture moves from the first groove M1 and/or the second groove M2 toward the terminal hole 41, the foreign matter or moisture will fall into the terminal hole 41 due to the ridge 230 and the groove M1X. The situation can be prevented.
In this configuration, the height of the peak 230 is approximately the same height as the top of the first groove M1, and the battery 100 can also be placed on the peak 230, which is advantageous for holding the battery 100. Note that the groove M1X may have the same shape as the first groove M1, or may be a groove different from the first groove M1. Moreover, although the case where there is one groove M1X is illustrated, two or more grooves M1X may be provided.

FIG. 9 is a diagram showing a side cross section of the first groove portion 221A together with the surrounding structure.
As shown in FIG. 9, each of the first grooves M1 is formed in a concave shape whose groove width becomes narrower toward the bottom, and the pitches (intervals) of adjacent first grooves M1 are approximately the same. The depth d1 and the interval W1 of the first groove M1 are formed to a size that allows foreign matter that is expected to adhere to the battery 100 to enter. In this configuration, the depth d1 of the first groove M1 is approximately the same value, for example, 2 mm. Further, the interval W1 between the first grooves M1 is approximately the same value, which is twice or more the depth d1 of the first grooves M1, and is, for example, 4.5 mm. In other words, the relationship is that depth d1 of the first groove M1<distance W1 of the first groove M1.

The tops T1 of the mountains are located between the adjacent first grooves M1, and the bottom surface 103 of the battery 100 is placed on each top T1. In this configuration, the mountain top T1 is formed as a flat surface. Note that the width TW of the flat surface is smaller than the depth d1 of the first groove M1, for example, 1.5 mm (TW<d1). By making the top portion T1 of the mountain a flat surface, the contact area with the bottom surface 103 of the battery 100 can be increased, which is advantageous for holding the battery 100.

The peaks T1 located between the adjacent first grooves M1 function as reinforcing ribs that reinforce the bottom plate 40. Therefore, it is advantageous for improving the strength of the bottom plate 40. Note that the mountain top T1 corresponds to a "non-groove portion in which a groove is not formed" in the present disclosure. The top portion T1 of the mountain is not limited to a flat surface, and may be changed to an appropriate shape.

Note that, similarly to the first groove M1, the depth and width of the second groove M2 are set so that foreign matter that is expected to adhere to the battery 100 can enter therein. For example, the depth and width of the first groove M1 and the second groove M2 may be the same or may be different.
In this configuration, as shown in FIG. 7, the second grooves M2 are provided one by one at intervals on the left and right, but the configuration is not limited to this. For example, a plurality of second grooves M2 may be provided in parallel to each other. Furthermore, the tops of the ridges corresponding between the second grooves M2 may be made flat.

As described above, the protrusions 213 having a hexagonal cross section that protrude downward are formed on the back surface of the bottom plate 40, and these protrusions 213 function as reinforcing ribs that reinforce the bottom plate 40. That is, the reinforcing ribs on the front surface (facing surface) of the bottom plate 40 are simple linear ribs, whereas the reinforcing ribs on the back surface of the bottom plate 40 are polygonal ribs different from the simple linear shape. If the reinforcing ribs on the back side of the bottom plate 40 are made into linear ribs, in the areas where the reinforcing ribs on the front side and the reinforcing ribs on the back side coincide, a locally thick part will be formed in a straight line shape, and the strength of the surrounding area will be reduced. There is a risk that the balance may become uneven or that there may be areas where stress concentration is likely to occur. In this configuration, the reinforcing ribs on the back surface of the bottom plate 40 are ribs that are not linear, thereby suppressing unevenness in the strength of the bottom plate 40.

In this configuration, the battery case 32, the terminal hole 41, the plurality of recesses 201, the plurality of connecting parts 211, the groove 221, the peak 230, and the groove M1X are integrally molded using a resin material. . In this case, by using a known resin molding method, the shape of each part can be manufactured easily and with high precision in a short time. However, the method is not limited to integral molding, and any part may be manufactured as a separate part, or may be manufactured by cutting or the like. For example, any one of the terminal hole portion 41, the plurality of recesses 201, the plurality of connecting portions 211, the groove portion 221, the peak portion 230, and the groove M1X may be manufactured by hole machining or cutting. Moreover, the case is not limited to the case where a resin material is used, and all or a part thereof may be manufactured using parts other than a resin material, for example, a carbon material or a metal material.

As explained above, the battery case 32 of the present embodiment has the terminal hole 41 and the groove 221 on the opposing surface facing the battery 100, and the terminal hole 41 extends from the center CP of the opposing surface. It is provided at a position offset to the rear, which is the first direction α. Further, the groove portion 221 has a first groove portion 221A extending in the left-right direction perpendicular to the first direction α among the directions along the surface of the opposing surface. This makes it possible to prevent foreign matter such as sand attached to the bottom surface 103 of the battery 100 from entering the groove 221 and to prevent the foreign matter from moving toward the terminal hole 41 side. Therefore, it is possible to avoid a situation in which the holding of the battery 100 and the terminal connections are affected by foreign matter attached to the battery 100.

Note that even if the first groove portion 221A extends in a direction slightly different from the direction orthogonal to the first direction α, it becomes difficult to move foreign matter toward the terminal hole portion 41 side. Therefore, it is preferable that the first groove portion 221A extends in a direction substantially orthogonal to the first direction α. Here, the direction substantially orthogonal to the first direction α includes the same direction as the orthogonal direction, as well as all directions in which foreign matter is difficult to move toward the terminal hole 41 side. This "direction substantially perpendicular to the first direction α" corresponds to the "second direction" of the present disclosure.

Further, the first groove portion 221A has a plurality of first grooves M1 that are parallel to each other. According to this configuration, the range of the first groove M1 is expanded, making it easier to capture foreign matter. Furthermore, even if a foreign object that has entered one of the first grooves M1 comes out of that first groove M1, it will enter the adjacent first groove M1, making it difficult for the foreign object to move out of the first groove portion 221A. Note that the first grooves M1 are preferably substantially parallel. Note that "substantially parallel" in the present disclosure includes not only parallel but also all directions effective for capturing foreign objects.

Further, the plurality of first grooves M1 are provided over half or more of the opposing surface. According to this configuration, foreign matter from the battery 100 can be easily captured by any of the first grooves M1. Although it is desirable that the plurality of first grooves M1 be provided over half or more of the opposing surface, they may be provided over less than half of the opposing surface.

Moreover, the plurality of first grooves M1 extend over substantially the entire length of the opposing surface in a direction perpendicular to the first direction α. According to this configuration, the first groove M1 can be made as long as possible, making it easier to catch foreign objects from the battery 100, and making it easier to retain the foreign objects in the first groove M1. Note that it is preferable that the plurality of first grooves M1 extend over substantially the entire length of the opposing surface in a direction substantially orthogonal to the first direction α. In this case, the "substantially orthogonal direction" includes directions other than orthogonal directions within a range effective for capturing foreign objects, etc., and corresponds to the "second direction" of the present disclosure.

Further, a mountain top portion T1 corresponding to a non-groove portion where no groove is formed is provided between the plurality of first grooves M1. According to this configuration, the non-groove portion facilitates reinforcing the region of the opposing surface and suppressing movement of foreign matter between the adjacent first grooves M1.
Further, the non-groove portion has a flat surface at the top. According to this configuration, the battery 100 can be easily placed in the non-groove portion, the contact area with the battery 100 is increased, and it is advantageous for holding the battery 100.

Furthermore, the plurality of first grooves M1 are equally spaced. Therefore, the number of first grooves M1 per unit area can be made uniform, making it easier to evenly capture foreign substances. In addition, although it is preferable that the plurality of first grooves M1 are approximately equally spaced, it is not necessary to limit the first grooves to be equally spaced. Note that "approximately equal intervals" in the present disclosure includes not only equal intervals but also a range in which the number of first grooves M1 per unit area can be considered to be equivalent.

Further, the plurality of first grooves M1 have the same depth d1. Therefore, by setting the depth d1 of the first groove M1 to a depth sufficient to allow foreign matter to enter, it is possible to appropriately avoid a situation where the foreign matter affects the holding of the battery 100 and the terminal connections. Note that the plurality of first grooves M1 need only have approximately the same depth within a range that is effective for trapping foreign matter.

Further, the interval W1 between the first grooves M1 is larger than the depth d1 of the first grooves M1. According to this configuration, the depth d1 of the first groove M1 can be suppressed while foreign matter can be easily inserted into the first groove M1. In this configuration, by setting the interval W1 between the first grooves M1 to be at least twice the depth d1 of the first groove M1, the depth d1 of the first groove M1 can be further suppressed while foreign matter is kept in the first groove M1. Easier to put in. Note that the interval W1 between the first grooves M1 may be less than twice the depth d1 of the first grooves M1, or may be made smaller than the depth d1 of the first grooves M1 if it is effective for capturing foreign matter. You can.

Furthermore, the groove portion 221 has a second groove portion 221B corresponding to another groove portion that intersects with the first groove portion 221A and extends in the first direction α. According to this configuration, foreign matter such as sand attached to the bottom surface 103 etc. of the battery 100 can be allowed to enter the second groove portion 221B, and the movement of foreign matter in the first groove M1 can be restricted at the position of the second groove portion 221B. can do. Note that the direction, number, and shape of the second groove portion 221B may be changed as appropriate. For example, the direction in which the second groove portion 221B extends may be changed within the range of the direction intersecting the first groove portion 221A. , the number of second grooves 221B may be increased, or the second grooves 221B may be omitted.

Further, the second groove portion 221B is provided so as not to be connected to the terminal hole portion 41. According to this configuration, it is possible to suppress foreign objects and the like from falling into the terminal hole 41 through the second groove 221B.
Moreover, since the opposing surface has communication holes 201H, 202H, and 203H that communicate the inside and outside of the battery case 32, moisture and the like that have entered the battery case 32 can be discharged through the communication holes 201H, 202H, and 203H.

Further, the battery case 32 has a protrusion 213 on the back surface of the opposing surface that protrudes in a shape different from the shape of the groove 221. Therefore, the protrusion 213 can reinforce the facing surface. In addition, it becomes easier to avoid a situation where a locally thick portion is formed into a straight line between the groove portion 221 and the protrusion portion 213, and it becomes easier to suppress unevenness in strength of the opposing surfaces.
Furthermore, since the protrusion 213 has a polygonal cross section and a protruding shape, the reinforcing effect of the protrusion 213 can be easily enhanced. Further, since the protrusions 213 have a plurality of polygonal cross sections that are adjacent to each other and share at least one side, the reinforcing effect can be further enhanced. Note that the shape and number of the protrusions 213 may be changed as appropriate within a range that provides a reinforcing effect.

The present invention is not limited to the configuration of the above-described embodiments, and various changes can be made without departing from the gist thereof.
For example, as shown in FIG. 10, a flat portion 221C may be provided instead of the second groove portion 221B. The flat portion 221C is a flat portion extending at the same height in the direction intersecting the first groove M1. The height of the flat portion 221C is below the top of the first groove M1 and higher than the deepest portion of the first groove M1, but it is not limited to this height. The flat portion 221C of this configuration is provided at the same position as the second groove portion 221B. The flat portion 221C functions as a reinforcing rib that reinforces the bottom plate 40 and as a connecting member that connects each first groove M1 of the first groove portion 221A, and is therefore advantageous in improving the strength of the bottom plate 40. Further, the flat portion 221C also functions as a partition wall that partitions each first groove M1 of the first groove portion 221A. Therefore, it is possible to restrict the movement of foreign matter within the first groove M1.

Further, the flat portion 221C is provided so as not to be connected to the terminal hole 41. Therefore, foreign objects and the like can be prevented from falling into the terminal hole 41 through the flat portion 221C.
Note that the direction, number, and shape of the flat portion 221C may be changed as appropriate. For example, the direction in which the flat portion 221C extends within the range of the direction intersecting the first groove portion 221A may be changed, or the direction, number, and shape of the flat portion 221C may be changed. The number of portions 221C may be increased, or the flat portion 221C may be omitted.

Further, in this embodiment, a manual type case in which the second terminal 54 passes through the terminal hole 41 in conjunction with the operation of the holding handle 62 has been exemplified, but the configuration is not limited to this. For example, either the second terminal 54 or the first terminal 108 may be fixed at a position where it is connected to the other terminal when the battery 100 is housed. In this case, either the first terminal 108 or the second terminal 54 will pass through the terminal hole 41.
Further, an actuator for moving the first terminal 108 on the battery 100 side toward the second terminal 54 on the battery case 32 side and/or an actuator for moving the second terminal 54 toward the first terminal 108 may be provided. You can also do this.

Moreover, although the case where the battery 100 and the battery case 32 have a substantially rectangular parallelepiped shape has been exemplified, they may have a rectangular parallelepiped shape without curved surfaces, or may have a shape other than a rectangular parallelepiped. In that case, at least a part of the side surface of the battery 100 is made into a curved shape, and at least a part of the battery case 32 is made into a curved shape so that the battery 100 can be stored. This makes it easier to avoid situations where the

Further, although the battery case 32 is configured to accommodate and hold the battery 100, the present invention is not limited to this, and the battery case 32 may place and hold the battery 100 with at least a portion of it exposed. A configuration may also be used.
