  By the way, the vehicle door opening and closing drive device as described above may be transported in a unit including at least a frame portion, a pulley, an endless toothed belt, and a bracket before being attached to a vehicle. At this time, since the bracket is fixed to the endless toothed belt rotatably wound around the pulley, the bracket may move relative to the frame portion. Therefore, in the vehicle door opening and closing drive device as described above, there is room for improving the handling during transportation, in that the bracket may move relative to the frame portion.

  The present invention has been made in view of such circumstances, and an object thereof is to provide a vehicle door opening and closing device having a good handling property at the time of transportation.

  A vehicle door opening and closing apparatus for solving the above-mentioned problems is a vehicle door opening and closing apparatus for opening and closing a slide door of a vehicle, and is rotatably supported by the support member extending in the moving direction of the vehicle door and the support member. A plurality of pulleys, a drive belt wound around the plurality of pulleys, and a bracket connected to the drive belt, and the support member has a holding portion for detachably holding the bracket.

  According to the above configuration, since the holding portion of the support member holds the bracket, movement of the bracket relative to the support member can be suppressed when the vehicle door opening and closing device is transported. When the vehicle door opening and closing device is attached to the vehicle, the bracket may be removed from the holding portion. As a result, the handleability at the time of conveyance of the door opening and closing device for vehicles can be improved.

  In the vehicle door opening and closing apparatus, the support member extends inward in the width direction of the vehicle as it travels from the front end of the first support member to the front of the vehicle. It is preferable that the second support member is provided, and the holding portion is provided on the outer side in the width direction of the first support member.

  The vehicle door opening and closing device is generally assembled from the outside to the inside with respect to the vehicle body when the vehicle is assembled. In this respect, according to the above configuration, since the holding portion is provided on the outer side in the width direction of the vehicle of the support member, the operator can use the bracket held by the holding portion as a hand-held portion. Further, when the support member is assembled to the vehicle, the second support member is disposed inward in the width direction of the vehicle than the first support member. Therefore, by providing the holding portion on the first support member, when assembling the vehicle door opening / closing device to the vehicle, the operator does not have to put the hand holding the bracket to the inside in the width direction of the vehicle.

  In the door opening and closing apparatus for a vehicle, the support member is a pair of support walls extending in the longitudinal direction at intervals in a direction intersecting both the longitudinal direction of the support member and the width direction. Preferably, the drive belt is accommodated between the pair of support walls, the holding portion is separated by the pair of support walls, and the bracket is held by holding the bracket.

  According to the above configuration, the bracket can be held by holding the bracket in the holding portions provided on the pair of support walls. For this reason, the holding portion can be configured by diverting the shape of the pair of support walls. In addition, the bracket can be easily attached to and detached from the support member.

  According to the above configuration, when the holding portion holds the bracket, the concave portion of the holding portion and the convex portion of the bracket are engaged. As a result, movement of the bracket in the circumferential direction of the drive belt can be suppressed.

  In the vehicle door opening and closing device, it is preferable that one of the support walls of the pair of support walls has a rib that protrudes toward the other support wall.

  According to the above configuration, by providing the rib on one of the support walls, the bracket can be held more firmly between the pair of support walls. As a result, movement of the bracket in the axial direction of the drive belt can be suppressed.

  In the door opening and closing apparatus for a vehicle, the support member is a pair of support walls extending in the longitudinal direction at intervals in a direction intersecting both the longitudinal direction of the support member and the width direction. It is preferable that the drive belt be accommodated between the pair of support walls, and the holding portion hold the bracket by holding the bracket by the pair of support walls.

  According to the above configuration, the bracket can be held to the support member by holding the bracket by the pair of support walls. For this reason, the holding portion can be configured by diverting the shape of the pair of support walls. In addition, the bracket can be easily attached to and detached from the support member.

  In the vehicle door opening and closing device, the holding portion is a first restricting portion that restricts movement of the bracket in one of the longitudinal directions in a state in which the bracket is held between the pair of support walls; And a second restricting portion that restricts the movement of the bracket to both sides in the width direction in a state where the movement of the bracket to one of the longitudinal directions is restricted by the first restricting portion. Is preferred.

  According to the above configuration, in a state in which the bracket is held by the support wall, the bracket in the longitudinal direction of the support member from the side not regulated by the first regulation portion to the position regulated by the first regulation portion in the longitudinal direction of the support member By moving the bracket, the bracket can be easily held on the support member. In addition, when the operator uses the bracket as a hand-held portion and the vehicle door opening / closing device is assembled to the vehicle while the bracket is held, the widthwise direction of the vehicle is not caused by the second restricting portion. It is possible to freely adjust the position of the vehicle opening / closing device in Then, after disposing the vehicle door opening and closing device with respect to the vehicle, holding the bracket can be easily released by moving the bracket to the side where movement is not restricted by the first restricting portion in the longitudinal direction of the support member.

  According to the above configuration, the first restricting portion can be formed only by changing the thickness of the support wall. As a result, it is not necessary to separately provide a member corresponding to the first restricting portion on the support member, and an increase in the number of parts can be suppressed.

  In the vehicle door opening and closing apparatus, the support member suppresses movement of the bracket in the other longitudinal direction in a state in which movement of the bracket in the longitudinal direction is restricted by the first restricting portion. It is preferable to further have a projection.

  According to the said structure, it can suppress that holding | maintenance of a bracket is cancelled | released by the vibration during transport of a door operator, for example.

First Embodiment
Hereinafter, a door opening and closing mechanism configured including the first embodiment of the vehicle door opening and closing device (hereinafter, also referred to as “door opening and closing device”) will be described.

  In the following description, the width direction of the vehicle is "width direction X", the longitudinal direction of the vehicle is "longitudinal direction Y", and the vertical direction (vertical direction) of the vehicle is "vertical direction Z".

  As shown in FIG. 1, the door opening and closing mechanism 3 of the present embodiment is a mechanism for opening and closing a vehicle door 2 (sliding door) that closes an opening 1 a that opens in a side portion of the vehicle main body 1. That is, the door opening and closing mechanism 3 opens and closes the vehicle door 2 by moving the vehicle door 2 forward or backward.

  As shown in FIG. 2, the door opening and closing mechanism 3 includes the lower rail 4, the roller unit 5, and the door opening and closing device 100. The lower rail 4 is extended along the lower edge of the opening 1 a of the vehicle body 1. The roller unit 5 connects the door opening and closing device 100 and the vehicle door 2. The roller unit 5 also has a roller 5 a that engages with the lower rail 4. When the roller 5 a of the roller unit 5 rotates with respect to the lower rail 4, the roller unit 5 moves along the lower rail 4.

  As shown in FIG. 3, the door opening and closing device 100 is connected to a long frame 10, a drive belt 40 disposed along the frame 10, a drive unit 30 that rotationally drives the drive belt 40, and the drive belt 40. And a bracket 50.

  As shown in FIG. 3, the frame 10 is configured to include a first frame 11 disposed on the rear side of the vehicle body 1 and a second frame 12 disposed on the front side of the vehicle body 1. The first frame 11 is bent with respect to the second frame 12. In the present embodiment, the frame 10 corresponds to an example of the “support member”, the first frame 11 corresponds to an example of the “first support member”, and the second frame 12 corresponds to an example of the “second support member” Do.

  As shown in FIG. 2, when the door opening and closing device 100 is attached to the vehicle body 1, the longitudinal direction of the first frame 11 becomes the longitudinal direction Y, and the longitudinal direction of the second frame 12 moves forward. The direction is toward the inside of the main body 1. Further, in plan view of the door opening and closing apparatus 100 attached to the vehicle body 1, the side where the angle between the first frame 11 and the second frame 12 is 180 degrees or more is the vehicle outer side in the width direction X The side in which the angle between the first frame 11 and the second frame 12 is less than 180 degrees is the inside of the vehicle in the width direction X.

  As shown in FIG. 4, the frame 10 has a pair of support walls 13 (a first support wall 131 and a second support wall 132) and a longitudinal wall 14 extending in the longitudinal direction. The pair of support walls 13 and the vertical wall 14 have a substantially plate shape. The first support wall 131 and the second support wall 132 are integrated with the vertical wall 14 so as to sandwich the vertical wall 14 vertically. Therefore, the thickness direction of the vertical wall 14 and the thickness direction of the first support wall 131 intersect each other (orthogonal), and the thickness direction of the vertical wall 14 and the thickness direction of the second support wall 132 intersect each other (orthogonal) . Therefore, in the present embodiment, the cross-sectional shape in the longitudinal direction of the frame 10 is substantially H-shaped. Further, in the frame 10, an accommodation space 133 for accommodating the drive belt 40 is formed in a region surrounded by the vertical wall 14 and the pair of support walls 13. The frame 10 is preferably made of, for example, a resin material.

  As shown in FIGS. 3 and 4, two ribs 131 a are formed on the first support wall 131 of the first frame 11, and two recesses 132 a are formed on the second support wall 132 of the first frame 11. .

  The two ribs 131 a are provided from the vertical wall 14 to the end of the first support wall 131 outside the vehicle. The two ribs 131 a protrude from the first support wall 131 toward the second support wall 132.

  As shown in FIG. 5, the two recesses 132 a are formed with notches 132 b directed from the end of the second support wall 132 outside the vehicle toward the inside of the vehicle. The opening length L in the direction (longitudinal direction Y) orthogonal to the direction in which the notch 132b is formed changes as it progresses from the vehicle outer side to the vehicle inner side. That is, the opening length L of the notch 132b becomes gradually shorter as it goes inward of the vehicle, and further inward of the vehicle becomes a length corresponding to the diameter of the head 53b of the fastening member 53 described later. Further, the opening length L of the notch 132b is the longest at the end on the vehicle outer side.

  In the present embodiment, in the pair of support walls 13 of the frame 10, the portion in which the rib 131a and the recess 132a are formed constitutes an example of the “holding portion” that holds the bracket 50.

  As shown in FIG. 6, the drive unit 30 includes a motor 31, a drive pulley 32, a first driven pulley 33, a second driven pulley 34, a first tension pulley 35, and a second tension pulley 36. Prepare.

  The motor 31 and the drive pulley 32 are disposed inside the vehicle of the second frame 12. When the motor 31 is energized, the output shaft rotates in the forward direction and the reverse direction. The drive pulley 32 is rotated by the drive of the motor 31. Preferably, a reduction gear is provided between the drive pulley 32 and the motor 31. The first driven pulley 33 is disposed at the front end of the second frame 12, and the second driven pulley 34 is disposed at the rear end of the first frame 11. Further, the first tension pulley 35 is disposed on the vehicle inner side of the second frame 12 so as to be adjacent to the drive pulley 32, and the second tension pulley 36 is on the vehicle inner side of the connection portion of the first frame 11 and the second frame 12. Will be placed. In the present embodiment, the rotational axis direction of the drive pulley 32, the first driven pulley 33, and the second driven pulley 34 is the vertical direction Z.

  The drive belt 40 is an endless toothed belt in which both ends are connected and a large number of teeth (not shown) are formed on the inner surface. The drive belt 40 is wound around the drive pulley 32, the first driven pulley 33 and the second driven pulley 34. In this respect, in the present embodiment, the drive pulley 32, the first driven pulley 33, and the second driven pulley 34 correspond to "pulleys".

  Further, a constant tension is applied to the drive belt 40 by the first tension pulley 35 and the second tension pulley 36 in a state of being wound around the drive pulley 32, the first driven pulley 33 and the second driven pulley 34. . Specifically, the drive belt 40 is tensioned to such an extent that power can be transmitted from the drive pulley 32 to the drive belt 40 while leaving a bend to suppress the load when the drive belt 40 rotates. . Thus, the drive belt 40 can rotate in the direction corresponding to the rotation direction of the drive pulley 32.

  As shown in FIG. 7, the bracket 50 includes a first bracket 51, a second bracket 52, and a plurality of (two in the present embodiment) fastening members 53 for fastening the first bracket 51 and the second bracket 52; Have. The constituent material of the bracket 50 is preferably a material having a higher elastic modulus than the frame 10, and for example, a metal material is preferable.

  The first bracket 51 is substantially L-shaped. The first bracket 51 has a mounting structure 51 b for mounting the roller unit 5. A plurality of (two in the present embodiment) first fastening holes 51 a are formed through the first bracket 51 in the vertical direction Z. An internal thread is formed on the inner circumferential surface of the first fastening hole 51a.

  The second bracket 52 is substantially L-shaped to correspond to the first bracket 51. A plurality of (two in the present embodiment) second fastening holes 52 a are formed through the second bracket 52 in the vertical direction Z.

  The fastening member 53 is a general fastening screw having a screw portion 53a and a head portion 53b. The head 53b is hemispherical. The diameter of the head 53 b in a plan view corresponds to the opening length L of the recess 132 a formed in the second support wall 132.

  The first bracket 51 and the second bracket 52 sandwich the outer surface and the inner surface of the drive belt 40 at a position where the first fastening hole 51a and the second fastening hole 52a overlap. The first bracket 51 and the second bracket 52 are fastened by the fastening member 53 in a state in which the drive belt 40 is held. Thus, the bracket 50 is integral with the drive belt 40.

  The first bracket 51 is connected to the roller unit 5 via the mounting structure 51 b in a state where the door opening and closing device 100 is mounted to the vehicle body 1. Thus, the bracket 50 connected to both the drive belt 40 and the roller unit 5 transmits the driving force of the drive belt 40 to the roller unit 5.

  Next, with reference to FIG. 2 and FIG. 6, a state in which the door opening and closing apparatus 100 opens and closes the vehicle door 2 will be described.

  It is assumed that the drive pulley 32 rotates clockwise in plan view shown in FIGS. 2 and 6. Then, the drive belt 40 is rotated by the drive pulley 32 as a whole in the first rotation direction R1. Thus, the roller unit 5 connected to the bracket 50 moves forward, and the vehicle door 2 is closed. Further, in a plan view shown in FIGS. 2 and 6, it is assumed that the drive pulley 32 rotates counterclockwise. Then, the drive belt 40 as a whole rotates in a second rotation direction R2 which is a direction opposite to the first rotation direction R1. Thus, the roller unit 5 connected to the bracket 50 moves rearward, and the vehicle door 2 is opened.

  Next, with reference to FIG. 8 to FIG. 11, an operation and effect when transporting the door opening and closing device 100 of the present embodiment and when assembling the door opening and closing device 100 to the vehicle main body 1 will be described.

  The door opening and closing device 100 as in this embodiment may be assembled to the vehicle body 1 and the vehicle door 2 after being manufactured separately from the vehicle body 1 and the vehicle door 2. In this case, the door opening and closing device 100 may be transported alone.

  In this respect, the door opening and closing apparatus 100 according to the present embodiment can hold the bracket 50 on the frame 10. That is, as shown in FIG. 8, the bracket 50 is held by the frame 10 as shown in FIG. 9A by pushing the bracket 50 into the frame 10 in the direction indicated by the solid arrow.

  At this time, as shown in FIG. 10A, the head portion 53 b of the fastening member 53 of the bracket 50 engages with the recess 132 a of the second support wall 132. That is, when the head portion 53b of the fastening member 53 is pushed into the recess portion 132a, the head portion 53b is disposed at the back of the recess portion 132a while a portion of the recess portion 132a having a short opening length L is slightly elastically deformed. . In addition, after the head portion 53b is accommodated in the recess 132a, the fastening member 53 is less likely to come off the recess 132a due to the portion where the opening length L of the recess 132a is short.

  In this manner, when the recess 132a holds the head portion 53b of the fastening member 53, the movement of the bracket 50 in the front-rear direction Y and the width direction X can be suppressed. Furthermore, in the present embodiment, the head portion 53b of the fastening member 53 functions as a "convex portion". For this reason, it is not necessary to separately provide the bracket 50 with a member corresponding to the “convex portion” to be engaged with the concave portion 132 a.

  Further, as shown in FIG. 10B, the bracket 50 is sandwiched in the vertical direction Z by the pair of support walls 13 (first support wall 131, second support wall 132). Here, the distance between the tip of the rib 131 a protruding from the first support wall 131 and the second support wall 132 is slightly shorter than the distance between the upper surface and the lower surface of the bracket 50. That is, in a state where the bracket 50 is held between the pair of support walls 13 (the first support wall 131 and the second support wall 132), the rib 131a is slightly compressed. For this reason, the force of the pair of support walls 13 sandwiching the bracket 50 in the vertical direction Z is increased by the restoring force of the rib 131a.

  Thus, the movement of the bracket 50 in the vertical direction Z can be suppressed by holding the bracket 50 in the vertical direction Z by the pair of support walls 13. Furthermore, by providing the ribs 131a, the pair of support walls 13 can hold the bracket 50 more firmly.

  When the door opening and closing device 100 is assembled to the vehicle body 1 as shown in FIG. 11, the bracket 50 held by the frame 10 can be used as a hand-held portion. Here, the bracket 50 is provided on the vehicle outer side of the first frame 11. For this reason, it is not necessary for the worker to put a hand to the inside in the width direction X with respect to the vehicle body 1. Further, when connecting the bracket 50 and the roller unit 5, the engagement between the recess 132a and the head 53b may be released by pulling the bracket 50 to the outside of the vehicle.

  As described above, the frame 10 detachably holds the bracket 50 on the outside of the first frame 11, whereby the handling property when transporting the door opening and closing device 100 can be improved. That is, when the door opening and closing device 100 is transported, the bracket 50 can not move with respect to the frame 10, so that movement of the bracket 50 can be restricted or contact between the bracket 50 and the frame 10 can be restricted. There is no need to provide a configuration (eg, a cushioning material). Further, the workability at the time of assembling the door opening and closing device 100 to the vehicle main body 1 can be improved.

  The above embodiment may be modified as shown below.

  -A member corresponding to the "convex portion" may be separately provided on the bracket 50. For example, a protruding portion that engages with the recess 132 a may be welded to the bracket 50.

  -The structure which hold | maintains the bracket 50 with respect to the flame | frame 10 may not be restricted to the structure in this embodiment.

  For example, only one recess 132a and one rib 131a may be provided, or three or more may be provided. Further, the recess 132 a and the rib 131 a may be provided on either of the first support wall 131 and the second support wall 132.

  The bracket 50 may be provided with a “recess” and the frame 10 may be provided with a “convex”. In this case, the “recesses” are formed outward from the inner end in the width direction X.

  The bracket 50 may not be held by the pair of support walls 13. For example, the bracket 50 may be held by the frame 10 by forming a hole for inserting the bracket 50 in the vertical wall 14.

  -In addition to this, the structure for holding the bracket 50 with respect to the flame | frame 10 can be suitably changed as needed.

  The bracket 50 may be held by the second frame 12. In addition, it may be held inside the vehicle of the first frame 11 or the second frame 12. Even in this case, since the bracket 50 can be held with respect to the frame 10, the handling property of the door opening and closing device 100 during transportation can be improved.

Second Embodiment
Hereinafter, a second embodiment of the door opening and closing apparatus will be described with reference to FIGS. 12 and 13. The configuration of the door opening and closing apparatus of the second embodiment is different from the configuration of the door opening and closing apparatus of the first embodiment in the configuration of the “holding portion” provided in the frame 10 (first frame 11), The other points are common. Therefore, in the description of the configuration of the second embodiment, the same components as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof is omitted. Further, in the present embodiment, as in the first embodiment, the “holding portion” is provided in the first frame 11, and the longitudinal direction of the first frame 11 coincides with the front-rear direction Y. Therefore, in the following description, the “longitudinal direction” of the frame 10 according to the present invention may be referred to as “longitudinal direction Y” for convenience. In addition, in the following description, the front side of the vehicle in the front-rear direction Y is referred to as the front direction Y1, and the rear side of the vehicle in the front-rear direction Y is referred to as the rear direction Y2.

  12 (a) to 12 (c) are diagrams showing a process of holding the bracket 50 on the "holding portion" of the frame 10 of the present embodiment. FIG. 13 (a) is a side view of a state in which the “holding portion” holds the bracket 50 as viewed from the outer side in the width direction X from the outer side, and FIG. It is a figure which shows the B line arrow end view. In addition, in the support wall 13 of 2nd Embodiment, illustration of the site | part inside a vehicle on both sides of the vertical wall 14 is abbreviate | omitted for simplification.

  First, the configuration of the frame 10 (first frame 11) in which the "holding portion" of the present embodiment is formed will be described with reference to Figs. 12 (a) and 13 (b).

  As shown in FIG. 12A, the first support wall 131 and the second support wall 132 of the frame 10 are thicker than the thick portions 15a and 15b having a general thickness and the thick portions 15a and 15b. The thin thin portions 16a and 16b are formed respectively. In the thick portions 15a and 15b, restriction surfaces 151a and 151b intersecting (orthogonal) with the front-rear direction Y are formed at the boundary portions with the thin portions 16a and 16b. Further, in the respective thin portions 16a and 16b, notches 17a and 17b are formed inward from the outer end in the width direction X. In addition, the frame 10 is a sidewall 18a extending in the direction (vertical direction Z) approaching each other from the outer end in the width direction X of each thin portion 16a, 16b so as to be adjacent to each notch 17a, 17b. Each has 18b. The respective notches 17a and 17b are formed so that the first support wall 131 and the second support wall 132 do not overlap when viewed from the vertical direction Z at the portions where the side walls 18a and 18b are formed. . By the notches 17a and 17b, the formability at the time of manufacturing the frame 10 with a mold movable in the vertical direction Z is improved.

  As shown in the figure, in the present embodiment, the second bracket 52 (bracket 50) is formed by the portions of the pair of support walls 13 where the thin portions 16a and 16b are formed, the side walls 18a and 18b, and the vertical wall 14. A housing space 10 a for housing is formed. In addition, the frame 10 is positioned at a distance approximately equal to the dimension in the front-rear direction Y of the second bracket 52 from the control surfaces 151a and 151b of the thick portions 15a and 15b, and the frame 10 protrudes inward in the accommodation space 10a. It further comprises a strip 19. The housing space 10 a is slightly narrowed at the portion where the ridge portion 19 is formed.

  Here, with reference to FIG. 13 (b), the configuration of the frame 10 will be described in more detail.

  As shown in FIG. 13B, assuming that the distance between the thin portions 16a and 16b in the vertical direction Z is a distance d1, and the dimension of the second bracket 52 in the vertical direction Z is a dimension m1, the distance d1 is from the dimension m1. Is also set slightly longer. On the other hand, when the distance in the vertical direction Z of each thick portion 15a, 15b (shown by a two-dot chain line) is a distance d2, the distance d2 is set shorter than the dimension m1. Therefore, the pair of support walls 113 can hold the second bracket 52 at the portion where the thin portions 16a and 16b are formed, and the second bracket at the portion where the thick portions 15a and 15b are formed. It is comprised so that it is impossible to clamp 52.

  In addition, although the dimensional lines are not shown to avoid complication of the drawing, as shown in the drawing, the distance in the width direction X of the vertical wall 14 and the side walls 18a and 18b is the width direction X of the second bracket. It is set slightly longer than the size in. Further, the distance in the up-down direction Z between the tips of the side walls 18a and 18b is set shorter than the dimension m1 in the up-down direction Z of the second bracket.

  Thus, the frame 10 is configured to be able to receive the second bracket 52 in the receiving space 10a.

  Next, with reference to FIG.12 (b), (c) and FIG.13 (b), the process of holding the bracket 50 with respect to the flame | frame 10 in this embodiment is demonstrated.

  As shown in FIG. 12B, in order to hold the bracket 50 on the frame 10, first, thin portions 16a and 16b of the pair of support walls 13 are formed, and side walls 18a and 18b are formed. The second bracket 52 of the bracket 50 is held at the non-placed part. Next, as shown in FIG. 12C, the bracket 50 is slid in the backward direction Y2 until it abuts on the control surfaces 151a and 151b of the thick portions 15a and 15b. Then, movement of the bracket 50 in the backward direction Y2 is restricted by the thick portions 15a and 15b.

  Here, as shown in FIG. 13B, in the state where the movement of the bracket 50 in the backward direction Y2 is restricted, the bracket 50 is held in the width direction so as to be held between the side walls 18a and 18b and the vertical wall 14 Movement to both sides of X is restricted, and movement to both sides in the vertical direction Z is restricted so as to be held between the first support wall 131 and the second support wall 132.

  Thus, the "holding portion" of the present embodiment allows the bracket 50 to move in the forward direction Y1 and restricts the movement in the other direction to hold the bracket 50.

  In addition, as shown in FIG.12 (c), in the state in which the bracket 50 was hold | maintained, the protrusion part 19 has suppressed the movement of the bracket 50 to the front direction Y1.

  As described above, in the present embodiment, it can be said that the portions of the thick portions 15 a and 15 b where the control surfaces 151 a and 151 b are formed function as the “first restricting portion” according to the present invention. Further, it can be said that the side walls 18a, 18b and the vertical wall 14 function as the "second restricting portion" according to the present invention. Then, in the frame 10 of the present embodiment, portions of the thick portions 15a and 15b where the restriction surfaces 151a and 151b are formed, the side walls 18a and 18b, the vertical wall 14, and the pair of support walls 13 A "holding part" is formed. In the following description, the portions of the thick portions 15a and 15b where the control surfaces 151a and 151b are formed are also referred to as the first control portion S1, and the side walls 18a and 18b and the vertical wall 14 are combined to form the second control portion S2. Also say.

  Here, with reference to FIG.12 (a)-(c) and FIG.13 (a), (b), the effect by the "holding part" of 2nd Embodiment is shown. The following shows the effects and advantages exerted separately due to the difference from the configuration of the "holding portion" of the first embodiment, and is common to the effects and advantages obtained by providing the "holding portion" described in the first embodiment. The description of things is omitted.

  -As described above with reference to FIGS. 12 (a) to 12 (c), in the state where the bracket 50 is held between the pair of support walls 13, the bracket is set to the position restricted by the first restricting portion S1. The bracket 50 can be easily held to the frame 10 only by moving in the longitudinal direction (in the present embodiment, the backward direction Y2).

  In the state where the bracket 50 is held, the second restricting portion S2 restricts the movement of the bracket 50 with respect to the frame 10 on both sides in the width direction X. Therefore, when the operator uses the bracket 50 as a hand-held portion, for example, when assembling the door opening and closing device 100 inward from the outside in the width direction X with respect to the vehicle, the bracket 50 falls off with respect to the frame 10 The position of the door opening and closing device 100 in the width direction X can be freely adjusted without causing the door opening and closing.

  -After disposing the door opening and closing device 100 with respect to the vehicle, holding the bracket 50 can be easily released by moving the bracket 50 in the forward direction Y1.

  The first restricting portion S1 is formed at the boundary between the thick portions 15a and 15b of the support wall 13 and the thin portions 16a and 16b. As a result, it is not necessary to separately provide a member corresponding to the first restricting portion S1 on the frame 10, and an increase in the number of parts can be suppressed.

  -In the state in which the bracket 50 was hold | maintained, the protrusion part 19 has suppressed the movement of the bracket 50 to the front direction Y1. Thereby, for example, it can be suppressed that the holding of the bracket 50 is released due to the vibration during transportation of the door opening and closing device. In addition, it is preferable that the protrusion 19 narrows the accommodation space 10a to such an extent that a worker can release holding | maintenance of the bracket 50 smoothly.

  Hereinafter, the modification of 2nd Embodiment is shown. In addition, only the modification which concerns on the structure of the "holding part" of 2nd Embodiment is shown here, and the description of the modification common to 1st Embodiment is abbreviate | omitted. Needless to say, the modification common to the first embodiment can also be applied to the second embodiment.

  The thick portion and the thin portion do not necessarily have to be provided on both of the pair of support walls 13, and the thick portion and the thin portion are formed on any one of the pair of support walls 13. The boundary between the two may be the first restricting portion S1. Alternatively, the support wall 13 is separately provided with a stopper member (not shown) for restricting the movement of the bracket 50 in one of the longitudinal directions of the frame 10 by contacting the bracket 50 with the support wall 13. You may function as control part S1. As described above, the first restricting portion S1 may be any member that restricts the movement of the bracket 50 in one of the longitudinal directions of the frame 10, and the form thereof is not limited to the second embodiment.

  A restriction surface intersecting (orthogonal to) the width direction X may be provided at the boundary between the thick portion and the thin portion, and movement of the bracket 50 in the width direction X may be restricted by the restriction surface. The movement of the bracket 50 in the width direction X may be restricted by separately providing members corresponding to the side walls 18a and 18b to the support wall 13. As described above, the second restricting portion S2 only needs to restrict the movement of the bracket 50 to both sides in the width direction X, and the form thereof is not limited to the second embodiment.

  In the second embodiment, the protrusion 19 may not be provided. Even in such a case, it is possible to obtain the effects of the first restricting portion S1 and the second restricting portion S2 described above.
