Room 5. The first refrigerating compartment 2 is provided with double-opening refrigerating compartment doors 21 (21a) and 21 (21b), which are divided left and right (an example of the door). A pull-out type refrigerator compartment door 31 is provided in the second refrigerator compartment 3. The first freezing compartment 4 and the second freezing compartment 5 are provided with pull-out type freezing compartment doors 41, 51, 52, respectively. Each of these doors is kept closed by a magnet (not shown). Here, the left-right direction X refers to a left-right direction (a horizontal direction orthogonal to the vertical direction Z) when the refrigerator 1 is viewed from the front with the refrigerator 1 placed on the installation surface. In the present specification, in the refrigerator 1, a surface on which each door is provided is referred to as a front surface of the refrigerator 1, and a surface of the refrigerator 1 opposite to the front surface is referred to as a back surface. The front-rear direction Y is a direction between the front and the back of the refrigerator 1.

In this way, the refrigerator 1 is divided into an upper section, a middle section, and a lower section, and each storage space is provided. Further, in the first refrigerating compartment 2 arranged at the upper part of the refrigerator 1, refrigerating compartment doors 21 (21a), 21 are provided so that the first refrigerating compartment 2 can freely rotate around a rotation axis in the vertical direction Z. (21b).

In addition, in front of the refrigerator compartment doors 21 (21a) and 21 (21b) of the refrigerator 1, door opening instruction sections 22 (22a) and 22 (22b) for instructing the refrigerator compartment doors 21a and 21b to automatically open are provided, respectively. The door opening instruction sections 22 a and 22 b are electrically connected to the input system of the control section 20 provided in the refrigerator 1, so that when a user performs an operation for door opening instructions of the refrigerating compartment doors 21 a and 21 b (specifically, the hand is approached or contacted When the door opening instruction sections 22a and 22b are operated), a door opening instruction signal indicating the door opening instruction of the refrigerator compartment doors 21a and 21b is transmitted to the control section 20. The door opening instruction portions 22a and 22b are electrostatic sensors in this example. The present invention is not limited to this, and the door opening instruction sections 22a and 22b may appropriately adopt a conventionally known structure. The control unit 20 automatically controls the door opening device 100 based on the door opening instruction signals from the door opening instruction units 22a and 22b to automatically open the refrigerator compartment doors 21 (21a) and 21 (21b).

[Door opening device] <First Embodiment>

Next, the door opening device 100 of the first embodiment will be described with reference to FIGS. 1 to 5.

FIG. 2 is a schematic perspective view of a state where the refrigerator compartment doors 21 (21a), 21 (21b) and the door opening device 100 are taken out from the refrigerator 1 shown in FIG. 1 as viewed obliquely from above. FIG. 3 is a schematic perspective view of a state in which the upper cover 100 a of the door opening device 100 shown in FIG. 2 is taken out obliquely from the upper side and the refrigerator compartment door 21 a on one side is opened by the door opening device 100. FIG. 4 is a schematic perspective view showing a state in which the pushing-out member 111 is located at the standby position Sa in the door opening device 100 according to the first embodiment as viewed obliquely from below. FIG. 5 is a schematic perspective view of the state in which the pushing-out member 111 in the door opening device 100 of the first embodiment is moved from the standby position Sa to the pushing-out direction R1 as viewed obliquely from below. In addition, the moving mechanism 110 that moves the left and right pushing members 111 and 111 has substantially the same structure except that the left and right pushing members 111 are opposite to each other. Therefore, in FIGS. 4 and 5 and FIGS. 6 to 10 to be described later, the left pushing The structural part of the moving mechanism 110 in which the member 111 moves is shown as a representative.

As shown in FIG. 1, the door opening device 100 is provided on the upper surface of the refrigerator body 11 (specifically, the first refrigerating compartment 2). As shown in FIGS. 2 and 3, the door opening device 100 moves the two pushing members 111 and 111 to close the two refrigerator compartment doors 21 (21 a) and 21 (21 b) in the closed state by the pushing members 111 and 111, respectively. Push out and open. The door opening device 100 includes a moving mechanism 110 that moves the pushing members 111 and 111, a driving device 120 that drives the moving mechanism 110, and a support member 140.

The moving mechanism 110 moves the pushing members 111 and 111 so that the refrigerating compartment doors 21 (21a) and 21 (21b) can be pushed out. Specifically, the moving mechanism 110 is a structure that moves the pushing members 111 and 111 in the circumferential directions R and R. In this example, the moving mechanism 110 includes two rotating circular plates 112 and 112, a drive transmission mechanism 130, a position detection unit 113, and two cams 114 and 114. The circular plates 112 and 112 are rotated in a horizontal direction. The push-out members 111 and 111 are provided on the outer peripheral edge portion of the lower surface of the rotary discs 112 and 112 so as to protrude downward. The rotary discs 112 and 112 are supported by the support member 140 so as to be rotatable about a rotation axis in the vertical direction Z. The driving transmission mechanism 130 transmits a rotational driving force from the driving device 120 to the rotating circular plates 112 and 112. The position detection unit 113 (specifically, an encoder) detects the standby position Sa and the reverse position Sb of the pushing members 111 and 111. The cams 114 and 114 are provided on the upper part of the refrigerator compartment doors 21 (21a) and 21 (21b) so that the curved contact surfaces 114a and 114a face the moving mechanism 110 side. The pushing members 111 and 111 slide on the abutting surfaces 114a and 114a of the cams 114 and 114 by rotating the rotating discs 112 and 112, and push the cams 114 and 114 to open the refrigerator compartment doors 21 (21a) and 21 ( 21b).

The pushing-out members 111 and 111 are cylindrical members (specifically, pins) whose axial directions are along the up-down direction Z, and are fixed to the lower surfaces of the rotating discs 112 and 112. The driving device 120 includes a driving motor 121 that functions as a driving unit. The drive motor 121 is electrically connected to an output system of the control unit 20.

The drive transmission mechanism 130 is configured by a gear train. The drive transmission mechanism 130 includes a drive-side gear 131 (specifically, a worm gear), driven-side gears 132 and 132, and an intermediate gear group 133. drive The moving-side gear 131 is fixed to a rotation shaft 121 a of the drive motor 121. The driven-side gears 132 and 132 are provided on the outer peripheral surfaces of the rotating discs 112 and 112. The intermediate gear group 133 includes a first intermediate gear 133a, a second intermediate gear 133b, a third intermediate gear 133c, and fourth intermediate gears 133d and 133d. The first intermediate gear 133a meshes with the drive-side gear 131 and meshes with the second intermediate gear 133b. The second intermediate gear 133b meshes with the first intermediate gear 133a and meshes with the third intermediate gear 133c. The third intermediate gear 133c meshes with the second intermediate gear 133b and meshes with the fourth intermediate gears 133d, 133d. The fourth intermediate gears 133d and 133d mesh with the third intermediate gear 133c and mesh with the driven-side gears 132 and 132. Thereby, the rotational driving force from the drive motor 121 can be transmitted to the rotary discs 112 and 112 via the drive transmission mechanism 130. In addition, the rotating discs 112 and 112 are rotated in the same direction by interlocking with each other through the driving transmission mechanism 130 by the rotation of the driving motor 121.

The position detection unit 113 detects a detected piece (not shown) of the rotating circular plate 112. The position detection unit 113 is electrically connected to the input system of the control unit 20, and sends a standby position signal indicating the standby position Sa of the pushing members 111 and 111 and a reverse position signal indicating the reverse positions Sb and Sb of the pushing members 111 and 111 to the control. Department 20. The control unit 20 detects the standby position signal from the position detection unit 113 and controls the stopping operation of the ejection members 111 and 111 at the standby position Sa by the drive motor 121 and the rotation operation of the rotating discs 112 and 112 in the ejection directions R1 and R1. . In addition, the control unit 20 detects a reverse position signal from the position detection unit 113 and controls the reverse movement of the pushing members 111 and 111 by the drive motor 121 at the reverse positions Sb and Sb, and the rotation of the circular plates 112 and 112 with the pushing direction R1. , R1 rotates in opposite directions R2 and R2 in opposite directions.

The support member 140 constitutes the cabinet 15 of the door opening device 100. Openings 151 and 151 (see FIGS. 4 and 5) into and out of the pushing members 111 and 111 are provided at the front end of the box 15. Further, the case 15 is provided with a through-hole 15a (an arc-shaped slit hole in this example) that communicates with the openings 151 and 151 and allows the pushing members 111 and 111 to move in the circumferential direction R and R (refer to the figure) 4. Figure 5). The control unit 20 stops the pushing members 111 and 111 at the standby position Sa. Here, as the standby position Sa, for example, the opening 151, 151 is a position further inside (inside the cabinet 15) and a position further outside (outer of the cabinet 15) than the openings 151 and 151. In this example, the standby position Sa is a position outside the openings 151 and 151.

When opening the refrigerator compartment door 21b on the right side, the control unit 20 controls the drive motor 121 to rotate the right rotating disc 112 from the standby position Sa of the pushing member 111 on the right side to the pushing direction R1 to the reverse position Sb. The pushing member 111 is moved. As a result, the pushing member 111 slides the cam 114 on the right side while pushing the cam 114 to open the refrigerator compartment door 21 b on the right side. Then, the control unit 20 reversely rotates the right rotating disc 112 at the reverse position Sb in the reverse direction R2 to stop it at the standby position Sa. Accordingly, the pushing-out member 111 on the right returns to the standby position Sa. At this time, since the left rotating disc 112 rotates in the same direction as the right rotating disc 112, the left pushing member 111 is pulled in from the standby position Sa to the left opening 151, and then returns to the standby position Sa. That is, the pushing member 111 on the left side is pulled into the left opening 151 when the pushing member 111 on the right side pushes out the cam 114 on the right side. Therefore, the pushing member 111 on the left side does not abut against the cam 114 on the left side, and the refrigerator compartment door 21a on the left side is not opened. The opening operation of the refrigerator compartment door 21a on the left side is also only changed from the left and right, and is the same as the opening operation of the refrigerator compartment door 21b on the right side, and the description is omitted here. When the door opening instruction signal from the left door opening instruction unit 22a is sent, the control unit 20 starts a series of door opening operations on the left refrigerator door 21a. When the door opening instruction signal from the right door opening instruction unit 22b is sent, , A series of door opening operations to the refrigerator compartment door 21b on the right are started.

Here, the two pushing members 111 and 111 and the openings 151 and 151 have substantially the same function, and therefore, the pushing member 111 and the opening 151 on one side (here, the left side) will be described below as a representative.

Incidentally, in the door opening device 100, between the opening 151 into which the pushing member 111 is pulled and the pushing member 111 when exposed from the opening 151 to the outside, if an intruding object (not shown) such as a human finger penetrates and pushes out In the pull-in path of the member 111, there is a problem that an intruded object is caught between the opening 151 and the pushing member 111 when the pushing member 111 is pulled into the opening 151. Here, push The pull-in path of the output member 111 may be a movement trajectory of the entire push-out member 111 when the push-out member 111 is pulled into the opening 151.

In this regard, in the present embodiment, the door opening device 100 is provided with a pinch prevention member 160 between the opening 151 into which the pushing member 111 is pulled in and the pushing member 111 when exposed from the opening 151 to the outside, and this pinching The preventing member 160 is used to prevent the intrusion of the intruder between the opening 151 and the pushing member 111 when the pushing member 111 is pulled into the opening 151.

According to the present embodiment, since the pinch preventing member 160 is provided between the opening 151 into which the pushing member 111 is pulled in and the pushing member 111 exposed from the opening 151 to the outside, even if an intruding object such as a finger enters the pushing member, In the drawing-in path of 111, when the pushing-out member 111 is pulled into the opening 151, it is possible to effectively prevent the intrusive object from being caught between the opening 151 and the pushing-out member 111 by the pinch prevention member 160.

In the present embodiment, the sandwiching prevention member 160 includes an inclined member 161. The inclined member 161 is inclined so that the height h1 (refer to FIG. 4) decreases as it moves away from the opening 151. According to this, even if an intruder enters the drawing-in path of the pushing-out member 111, when the pushing-out member 111 is pulled into the opening 151, the intruding object can be moved along the inclined top surface 161a of the inclined member 161 more than the drawing-in path Since it is discharged outside in the height direction, it is possible to reliably prevent the intrusion of the intruder. The inclined top surface 161a has a flat shape in this example, but may be a convex or concave curved shape.

The inclined member 161 is formed on at least one of the two outer sides of the drawing-in path of the pushing-out member 111 (two outer sides in this example). The inclined member 161 is formed along the drawing-in path (the circumferential direction R in this example) of the pushing-out member 111. Although the inclined member 161 is not shown, it may be provided integrally with or in contact with or in contact with the peripheral edge portion of the opening 151 (the cover member 162 described later is removed in this example). When the inclined member 161 is provided close to the peripheral edge portion of the opening 151 (without contact), for example, the distance between the inclined member 161 and the peripheral edge portion of the opening 151 may be set such that an intruder such as a finger does not The distance that can be entered (for example, about 3 mm or less). Thereby, it is possible to reliably prevent an intruder such as a finger from entering between the inclined member 161 and the opening 151.

Incidentally, from the viewpoint of shortening the time from the opening instruction of the refrigerating compartment door 21 to the pushing-out member 111 pushing out the refrigerating compartment door 21, the door opening device 100 is located at the standby position Sa of the pushing-out member 111 outside the opening 151 In the state (state shown in FIG. 4), when the pushing-out member 111 moves not only from the standby position Sa to the pushing-out direction R1 but also to the reverse direction R2 and is pulled into the opening 151 from the standby position Sa, There is a case where an intruding object is caught between the opening 151 and the pushing member 111 when being pulled into the opening 151 from the standby position Sa. In particular, when the door is pushed out by the pushing member 111 on one door side as in the present embodiment, the pushing member 111 on the other door side is pulled into the opening 151. When the door is opened, the door-opening member 111 is pulled into the opening 151 while the other door-side pushing member 111 is exposed. Therefore, there is a possibility that a user's finger or the like may be caught.

In this regard, in this embodiment, the pinch prevention member 160 includes a cover member 162 (a tunnel-shaped cover member in this example). The cover member 162 is formed to cover at least a part (the whole or a part) of the pull-in path of the pushing-out member 111. According to this, when the pushing member 111 is pulled into the opening 151 from the standby position Sa, it is possible to prevent an intruding object such as a finger from entering between the opening 151 and the pushing member 111, thereby reliably preventing the intrusion of the intruding object.

The cover member 162 is formed along the drawing-in path of the pushing-out member 111. The cover member 162 is provided integrally with or in contact with or close to the peripheral edge portion of the opening 151 (in this example, integrally). Although the illustration is omitted, when the cover member 162 is provided close to (not in contact with) the peripheral edge portion of the opening 151, for example, the distance between the cover member 162 and the peripheral edge portion of the opening 151 can be set as an intruder such as a finger A distance that does not enter (for example, about 3 mm or less). With this, it is possible to reliably prevent intruding objects such as fingers from entering between the cover member 162 and the opening 151. In addition, the inclined member 161 is integral with or in contact with or close to the end of the cover member 162 on the opposite side to the opening 151 (in this example, integrally). Way setting. Although the illustration is omitted, when the inclined member 161 is provided so as to approach (not contact) an end on the opposite side of the opening 151 of the cover member 162, for example, the distance between the inclined member 161 and the cover member 162 can be set The distance (for example, about 3 mm or less) where an intruder such as a finger does not enter. With this, it is possible to reliably prevent intruding objects such as fingers from entering between the inclined member 161 and the cover member 162.

Here, the inclined member 161 and / or the cover member 162 function as a protection member 16 that protects an intruder from the pushing member 111 when the pushing member 111 is pulled into the opening 151. Therefore, in this embodiment, the protection member 16 can reliably protect the intruder from the pushing member 111 when the pushing member 111 is pulled into the opening 151.

<Second Embodiment>

Next, the door opening device 100 according to the second embodiment will be described with reference to FIGS. 6 and 7.

6 and 7 are schematic perspective views showing a modified example of the cover member 162 in the door opening device 100 according to the second embodiment as viewed obliquely from below.

As shown in FIG. 6, in the door opening device 100 according to the second embodiment, the cover member 162 includes an opening portion 162 a that opens the lower side in the direction of gravity. Accordingly, even if foreign matter such as garbage enters the cover member 162, the foreign matter can be surely dropped downward from the open portion 162a. In this case, when a lubricant such as grease is applied to the pushing member 111 from the viewpoint of improving the sliding property with the cam 114, it is possible to suppress adhesion of foreign matter such as garbage to the pushing member 111, and it is particularly effective. Further, the amount of material forming the cover member 162 can be reduced, and thus the cost can be kept low.

The open portion 162 a is formed along the drawing-in path of the pushing-out member 111. As shown in FIG. 6, the opening portion 162 a may be opened as a whole, and the width d1 may be a process in which an intruder such as a finger does not enter. Distance (for example, about 3 mm or less). According to this, it is possible to reliably prevent an intruder such as a finger from entering the open portion 162a.

Incidentally, when the cover member 162 is provided with the opening portion 162a, depending on the width d1 of the opening portion 162a, an intruder such as a finger may enter the opening portion 162a. In this regard, as shown in FIG. 7, in the door opening device 100 according to the second embodiment, the cover member 162 is provided with a closing portion 162 b which closes at least a part (the whole or a part of the opening portion 162 a in this example) It is the whole except the through hole 162c described later). According to this, it is possible to prevent intruded objects such as fingers from entering the occlusion portion 162b.

Incidentally, if the blocking member 162b is provided in the cover member 162, it is easy to deposit foreign matter such as garbage on the blocking member 162b. In this regard, in the present embodiment, the blocking portion 162b is provided with a through hole 162c. Accordingly, even if foreign matter such as garbage falls into the blocking portion 162b, the foreign matter can be dropped downward from the through hole 162c.

There may be one or a plurality of through holes 162c. The through hole 162c may have a circular shape, an elliptical shape, a polygonal shape, or a long shape. When the through-hole 162c has a long shape, it is formed so as to follow the drawing-in path of the pushing-out member 111. According to this, it is possible to reliably drop foreign matter such as garbage along the drawing-in path of the pushing-out member 111. In this example, the shape of the through hole 162c extends along the direction (specifically, the circumferential direction R) of the pull-in path of the pushing member 111, and a plurality of side-by-side is provided in the width direction n (specifically, the radial direction). Slit shape.

In addition, although not shown, the inner surface of the closing portion 162b may be replaced with the through-hole 162c or in addition to the through-hole 162c toward the side opposite to the opening 151 in the direction of the drawing-in path of the pushing-out member 111 (the pushing-out direction R1). ) Inclines toward the lower side in the direction of gravity. According to this, even if foreign matter such as garbage falls into the blocking portion 162b, the foreign matter can be surely discharged downward by rolling along the inclined surface (not shown).

<Third Embodiment>

Next, the door opening device 100 according to the third embodiment will be described with reference to FIGS. 8 to 10.

FIG. 8 is a schematic perspective view showing a state where a part of the moving member 163 in the door opening device 100 according to the third embodiment is viewed obliquely from below.

In the door opening device 100 according to the third embodiment, the sandwiching preventing member 160 includes a moving member 163 (specifically, a rail-shaped long member). The moving member 163 is formed in at least a part (the whole or a part) of the drawing-in path of the pushing-out member 111. In addition, the moving member 163 moves (integrate) with the movement of the pushing member 111. According to this, at least a part (the whole or a part) of the space between the pushing member 111 and the opening 151 when the pulling-in path of the pushing member 111 is exposed from the opening 151 to the outside can be filled. Alternatively, when the sandwiching prevention member 160 includes the inclined portion 161 and / or the cover member 162 (hereinafter, sometimes referred to simply as the protection member 16), the pull-in path of the pushing-out member 111 is filled and exposed from the protection member 16 to the outside At least a part (whole or part) of the space between the pushing-out member 111 and the protective member 16 at this time. Thereby, it is possible to effectively prevent an intruded object from being caught between the pushing member 111 and the opening 151 or the protection member 16. Here, it is preferable that the height h2 of the end portion of at least the pushing member 111 side of the moving member 163 be equal to or higher than the height of the pushing member 111. Moreover, it is preferable that the width d2 of an end portion of at least the pushing member 111 side of the moving member 163 be equal to or greater than the width (the dimension in the width direction) of the pushing member 111. In this example, the moving member 163 is formed into an arc shape along the drawing-in path of the pushing member 111 and is inserted into the opening 151. The moving member 163 is fixed to the outer peripheral edge portion of the surface on the lower side of the rotating circular plate 112 along the direction of the drawing-in path of the pushing-out member 111 (the circumferential direction R in this example).

The moving member 163 is provided integrally or in contact with or close to the side surface of the pushing-out member 111 (closer in this example). When the moving member 163 is provided close to the side surface of the pushing member 111 (not in contact), for example, the distance between the moving member 163 and the side of the pushing member 111 can be set to a distance to which an intruder such as a finger cannot enter. (For example, about 3mm or less). borrow Accordingly, it is possible to reliably prevent an intruder such as a finger from entering between the moving member 163 and the pushing member 111.

9 and 10 are schematic perspective views showing a modified example of the moving member 163 in the door opening device 100 according to the third embodiment as viewed obliquely from below.

Incidentally, if an intruder enters the drawing path of the moving member 163, there is a possibility that the intruding object is caught between the opening 151 and the moving member 163 when the moving member 163 is pulled into the opening 151. This is particularly noticeable when the end portion 163a on the pull-in side of the moving member 163 is exposed from the opening 151 when the pushing member 111 is moved. Alternatively, when the sandwiching prevention member 160 includes the protective member 16 (the inclined member 161 and / or the cover member 162), if an intruder enters the drawing path of the moving member 163, the moving member 163 is protected. When the member 16 is pulled in, there is a possibility that an intruder may be caught between the protection member 16 and the moving member 163. This is particularly noticeable when the end portion 163 a on the pull-in side of the moving member 163 is moved outward from the protective member 16 when the pushing member 111 is moved. Here, the pull-in path of the moving member 163 may be a movement track of the entire moving member 163 when the moving member 163 is pulled into the opening 151 or the protective member 16.

In this regard, in the door opening device 100 according to the third embodiment, as shown in FIG. 9, regarding the height of the moving member 163, the whole of the moving member 163 or a part of the pull-in side (a part of the pull-in side in this example). h3 becomes higher toward the side opposite to the drawing-in side of the moving member 163 (the pushing-out direction R1 in this example). According to this, even if an intruder enters the drawing path of the moving member 163, when the moving member 163 is pulled into the opening 151 or the protective member 16, the intruding object can be pulled toward the moving member 163 along the height h3. The inclined top surface 163b, which becomes higher on the opposite side, is discharged to the outside in a height direction higher than the drawing-in path of the moving member 163, whereby the intrusion of the intruder can be reliably prevented. This case is particularly effective when the end portion 163 a on the pull-in side of the moving member 163 is moved from the opening 151 or the protection member 16 when the pushing member 111 is moved. and, The amount of material forming the moving member 163 can be reduced, and thus the cost can be suppressed low. The inclined top surface 163b has a flat shape in this example, but may be a convex or concave curved shape.

In the door opening device 100 according to the third embodiment, it is preferable that the protective member 16 further includes an inclined member 161 instead of or in addition to this structure. According to this, even if an intruder enters the drawing path of the moving member 163, when the moving member 163 is pulled into the protective member 16, the intruding object can be moved toward the moving member 163 along the inclined top surface 161a of the inclined member 161. The pull-in path is discharged outward in the height direction, thereby preventing the intrusion of the intruder.

When the end portion 163a on the pull-in side of the moving member 163 is moved from the opening 151 or the protective member 16 when the pushing member 111 is moved, the pulling of the moving member 163 when the pushing member 111 is moved The distance between the end portion 163a on the entrance side and the opening 151 or the protective member 16 can be a distance (for example, about 3 mm or less) to which the intruding object such as a finger cannot enter. Thereby, it is possible to reliably prevent an intruder such as a finger from entering between the end portion 163 a on the pull-in side of the moving member 163 and the opening 151 or the protection member 16.

In addition, although the protective member 16 may be provided, when the end portion 163a of the pull-in side of the moving member 163 is located in the opening 151 when the pushing member 111 is moved at the maximum, the protective member 16 may not be provided. In the case where the protective member 16 is provided, the inclined member 161 may be provided. However, in a case where the end portion 163a on the pull-in side of the moving member 163 is located in the protective member 16 when the pushing member 111 is moved at the maximum, There may be no inclined member 161.

In the present embodiment, as shown in FIG. 10, regarding the moving member 163, the width d3 of the whole or a part of the moving member 163 (the entirety in this example) is more toward the side opposite to the drawing side of the moving member 163 ( In this example, the pushing direction R1) becomes larger. According to this, even if an intruder enters the drawing path of the moving member 163, when the moving member 163 is pulled into the opening 151 or the protective member 16, the intruding object can be pulled in toward the moving member 163 along the width d3. Inclined side surfaces 163d and 163d that are larger on the opposite side and move outward in a wider width direction than the pull-in path of the moving member 163 With this, it is possible to reliably prevent the intrusion of the intruder. This case is particularly effective when the end portion 163 a on the pull-in side of the moving member 163 is moved from the opening 151 or the protection member 16 when the pushing member 111 is moved. Moreover, the amount of material forming the moving member 163 can be reduced, and thus the cost can be kept low. The inclined side surfaces 163d and 163d have a flat shape in this example, but they may also have a convex or concave curved shape.

Incidentally, even if a person touches the moving member 163, it is generally considered to be a contact from the front side. From this viewpoint, the moving member 163 may be inclined at least on the front side among the two inclined side surfaces 163d and 163d in the width d3.

In this example, regarding the moving member 163, the width d3 becomes smaller toward the pull-in side, and becomes smaller toward the base end side in the axial direction of the push-out member 111. According to this, it is possible to more easily discharge the intruding object along the inclined side surfaces 163d and 163d to the outside in a width direction wider than the drawing-in path of the moving member 163, thereby more reliably preventing the intruding object from being caught.
