  It is desired that the moving member guided by the guide rail in the object moving device stably moves the moving member with respect to the guide rail in order to move the moving object stably. For this reason, the moving member has a connecting portion with the end of the cable where the driving force is transmitted so that a moment does not occur with respect to the moving member in order to suppress a change in the relative position with respect to the guide rail. It is desirable to be configured at the approximate center in the width direction.

  However, the object moving device is desirably reduced in size and weight as in the case of an opening / closing body opening / closing device for an automobile, and the guide rail is also desirably reduced in width. Here, the guide rail and the carrier plate adopt an engagement structure having a protrusion that moves the carrier plate in the length direction of the guide rail and restricts the movement in the width direction and the thickness direction. Is common. In this engagement structure, when the width of the guide rail is narrowed, the portion of the moving member that overlaps the guide rail is also narrowed, so that the end portions of the guide rail in the width direction are close to each other, and the connecting portion is ensured in strength. For this reason, a predetermined width must be maintained, and as a result, the above-mentioned protrusion and the above-mentioned connecting portion come close to each other. Therefore, the space where the above-mentioned elastic member is arranged also becomes narrow, and the portion formed by the guide rail of the above-described engagement structure and the elastic member are likely to come into contact with each other. In the conventional structure, when the elastic member is disposed in the vicinity of the engagement structure, the elastic member contacts the protrusion when the elastic member abuts on the lifting guide mechanism side contact portion and deforms, and the locking portion Since there is a concern of causing problems such as dropping off from the housing, there are problems in productivity, such as limiting the material of the elastic member and adopting a fitting structure with high holding power that is difficult to assemble.

  Then, the objective of this invention is providing the target object moving apparatus with which the malfunction of the elastic member produced when an elastic member is arrange | positioned in the vicinity of a protrusion part was suppressed.

  The object moving device of the present invention includes a moving member, a main body portion having a base end and a terminal end in the length direction, and a ridge portion protruding from the main body portion and extending along the length direction, A guide rail that guides the moving member, a drum member, a drive source that is connected to the drum member and rotates the drum member, and one end is connected to the moving member, and winding and feeding are performed by rotation of the drum member A cable to be turned, a direction changing member for changing a direction in which the cable extends between the moving member and the driving source, and the moving member toward the proximal end side of the guide rail in contact with the moving member A movement restricting portion that restricts the movement of the object, and an object moving device that moves the moving member by driving the drive source, wherein one of the movement restricting portion and the moving member is in contact with the other Against A cable to which one end of the cable is connected provided at a position corresponding to the approximate center in the width direction of the guide rail when the moving member is guided by the guide rail. A connecting portion and a moving member side fitting portion that fits the protruding portion, and the impact relaxation portion is deformed by the contact when the moving member and the movement restricting portion are in contact with each other. The object moving device has a deformed part accommodating part that accommodates a deformed part of the elastic member generated by the contact, and the impact mitigating part is the deformed part. When there is no part accommodating portion, the elastic member and the protruding portion are brought into contact with each other by the contact, and are arranged at a position between the cable connecting portion and the moving member side fitting portion.

The elastic member 91 includes a fixing portion 91b housed inside the carrier plate (moving member 1), an elastic deformation portion 91a positioned outside the carrier plate (moving member 1), a fixing portion 91b, and an elastic deformation portion 91a. And an intermediate portion connecting the two. The elastic deformation portion 91a is disposed so as to face the outside of the carrier plate (moving member 1) in the moving direction of the carrier plate (moving member 1), and has a curved surface 91c that protrudes outward, and the carrier plate (moving). And an inner surface disposed on the member 1) side. In the elastic member 91, the edge of the inner surface and the edge of the curved surface 91c are connected on the same side by two planes extending in the direction in which the guide rail 2 extends, and face the outside of the carrier plate (moving member 1). It has a plate-like shape that is convex. The elastic member 91 includes a pair of bending portions 91c and 91d and a pair of engagement side portions 91e and 91f formed between the pair of bending portions 91c and 91d so as to be engageable with the holding portion 92. ing. The engagement side portions 91e and 91f are formed with a groove G along the axis X2 direction (thickness direction D3) of the elastic member 91, and the elastic member 91 is formed in a columnar shape in which the portions of the engagement side portions 91e and 91f are constricted. Is formed. On one end side (the lower side in FIGS. 8 and 9) of the groove G in the axis X2 direction, an engagement recess 91g that engages with an engagement protrusion 92c of a holding portion 92 described later is further formed. Further, the pair of curved portions 91c and 91d is formed with a groove G2 in a direction perpendicular to the direction of the axis X2 of the elastic member 91.

  On the other hand, as shown in FIGS. 4 and 5, the holding portion 92 has a pair of engaging portions 92a and 92b protruding toward each other so as to be engaged with the engaging side portions 91e and 91f. doing. As shown in FIG. 6, an inclined surface is formed from the pair of engaging portions 92a and 92b so that the elastic member 91 can be inserted in the thickness direction D3, and is formed in the groove G of the engaging side portions 91e and 91f. It has an engaging projection 92c that engages with the formed engaging recess 91g. Accordingly, when the elastic member 91 is inserted into the holding portion 92 in the thickness direction D3, the elastic member 91 is prevented from coming off in the thickness direction D3. In addition, the holding portion 92 has a space portion in which the intermediate portion can move when the elastic deformation portion 91a is deformed. In the present embodiment, the holding portion 92, the fixing portion 91b, and the deformation portion accommodating portion AC side. It has an inner wall surface provided with a gap forming portion (a step portion in FIG. 5) that can form a gap therebetween.

  The object moving device D of the present embodiment has a deformed portion accommodating portion AC that accommodates a deformed portion of the elastic member 91 generated by the contact between the moving member 1 and the movement restricting portion 8. As shown in FIG. 10 and FIG. 11 schematically shown, the deformed portion accommodating portion AC is not contacted by deformation when the elastic member 91 is deformed when the moving member 1 and the movement restricting portion 8 are in contact. It is comprised so that the part which protruded from the outer edge (refer the dashed-two dotted line in FIG. 11) of the elastic member 91 in this natural state can be accommodated.

  In the present embodiment, as shown in FIG. 12 and FIG. 13 (both are diagrams showing reference examples), when the impact relaxation portion 9 does not exist, the elastic member 91 and the elastic member 91 are brought into contact with each other. It arrange | positions in the position between the cable connection part 13 and the moving member side fitting part 14 (refer FIG. 10 and FIG. 11) that the protrusion part 22b contact | abuts (refer FIG. 13). In addition, the impact relaxation part 9 is the space | interval in the width direction D2 of at least one cable connection part 13 provided in the approximate center by the width direction D2 of the guide rail 2, and the moving member side fitting part 14. As long as it is provided. For example, in FIG. 1, the impact relaxation part 9 may be provided between the cable connection part 13b and the moving member side fitting part 14a.

  As shown in FIGS. 12 and 13, the elastic member 91 comes into contact with the ridge 22 due to the deformation due to the contact in a state where there is no deformation site accommodating part AC. However, as shown in FIG. 10 and FIG. 11, since the deformed portion accommodating portion AC is provided, the width of the guide rail 2 is shortened, and the outer edge and the protruding portion 22 in the natural state of the elastic member 91 are reduced. Even when the positions are close to each other, the deformed portion accommodating portion AC provides a space in which a part of the deformed portion of the elastic member 91 can escape so as not to face the protruding portion 22. Therefore, it can suppress that the deformation | transformation site | part of the elastic member 91 contact | abuts the protrusion part 22. FIG. Thereby, the elastic member 91 can be prevented from coming off due to the elastic member 91 coming into contact with the protruding portion 22. Moreover, since it can suppress that the deformation | transformation site | part of the elastic member 91 contact | abuts the protrusion part 22 by deformation | transformation site | part accommodating part AC, since the width | variety of the guide rail 2 can be made thinner than before, the object moving apparatus D can be reduced in size and weight. Further, as shown in FIGS. 12 and 13, when there is no deformed portion accommodating portion AC, the deformed elastic member 91 abuts on the ridge portion 22 and there is no further escape space for the elastic deformable portion 91 a. A strong stress is applied to the elastic deformation portion 91a, causing the elastic deformation portion 91a to be damaged. On the other hand, in the present embodiment, the deformation site accommodating portion AC has a refuge for the elastic deformation portion 91a, so that the elastic deformation portion 91a can be prevented from being damaged.

  In the present embodiment, the deformed portion accommodating portion AC is provided in the holding portion 92. However, when the elastic deformable portion 91a is deformed, the deformed portion accommodating portion AC may be deformed if it can be moved so as not to come into contact with the protruding portion 22. The part accommodating part AC may be provided other than the holding part 92, for example, on the side where the elastic member 91 is not provided among the moving member 1 and the movement restricting part 8.

  In the present embodiment, as shown in FIGS. 10 and 11, a support portion S that supports the elastic deformation portion 91 a is configured on the holding portion 92. The support portion S is separated from the elastic deformation portion 91a before the elastic deformation portion 91a contacts the other of the movement restricting portion 8 and the moving member 1 where the impact relaxation portion 9 is not provided. The elastic deformation portion 91a is supported when 91a and the other are in contact and elastically deformed. As described above, since the deformed portion accommodating portion AC is formed and the support portion S that supports the elastic deformable portion 91a is formed at the time of deformation, when the moving member 1 and the movement restricting portion 8 abut, The elastic member 91 is prevented from being damaged while securing the escape area of the deforming portion 91a, and the support portion S supports the elastic deforming portion 91a after the deformation. The contact of the deformable portion 91a can be prevented. In the present embodiment, the support portion S includes a first support portion S1 that supports the elastic deformation portion 91a that deforms in the length direction D1, and a second support portion S2 that supports the elastic deformation portion 91a that deforms in the width direction D2. It has. In the natural state of the elastic deformation portion 91a, the first support portion S1 and the elastic deformation portion 91a are separated so that the elastic deformation portion 91a can escape in the length direction D1 during elastic deformation, and the second support portion S2 The elastic deformation portion 91a is separated from the elastic deformation portion 91a so as to escape in the width direction D2 during elastic deformation. The support part S (first and second support parts S1 and S2) can be a support wall part that comes into contact when the elastic deformation part 91a is deformed. In addition, the support part S should just be provided so that deformation | transformation site | part accommodating part AC may be formed between the elastic deformation part 91a and the support part S. FIG. In FIG. 10 and FIG. 11, the support portion S is a first support portion S1 formed as a flat surface substantially perpendicular to the length direction D1, and a second support portion formed as a flat surface substantially perpendicular to the width direction D2. However, the shape of the support portion S is not particularly limited. For example, the support portion S may be formed as a curved surface formed so as to be able to support the elastic deformation portion 91a that is deformed in the length direction D1 and the width direction D2. Further, the support S may be inclined from a surface perpendicular to the length direction D1 or a surface perpendicular to the width direction D2. Since the second support portions S2 are provided on both sides in the width direction D2 and the elastically deformed elastic portions 91a are in contact with each other, the displacement in the width direction D2 during the collision of the elastically deformable portions 91a can be suppressed. It is possible to stabilize the carrier plate at the time. Further, when the first support portion S1 is provided with a step to form a space between the first support portion S1 and the elastic deformation portion 91a, the elastic deformation portion 91a is supported in a steady state, and the elastic deformation portion 91a is deformed. Alternatively, a part of the elastic deformation portion 91a may be accommodated.

  Further, as shown in FIG. 14, the pair of engaging portions 92a and 92b of the holding portion 92 has a length in the thickness direction D3 of one engaging portion 92a provided on the protruding portion 22 side. The engaging portion 92b may be formed to be shorter than the length in the thickness direction D3. In this case, for example, as shown in FIG. 14, the edge of the one engaging portion 92 a on the side of the main body portion 21 of the guide rail 2 is closer to the elastic member 91 side than the protruding portion 22 side of the guide rail 2. Thus, an extending portion E that protrudes toward the main body portion 21 of the guide rail 2 is formed. Thereby, compared with the case where there is no extension part E, the deformation | transformation toward the protrusion part 22 of the elastic member 91 can be suppressed more.
