The shaft support portion 35 is supported by the base plate portion 31 by fixing the nut member 35a to the front surface 31a of the base plate portion 31 by welding or the like. The support portion 34a of the locking claw portion 34 is fixed to the left plate surface 36a of the support plate portion 36 by welding or the like.

  The locking claw 34 engages the portion on the locking protrusion 34b side with the locking hole 7c provided in the front surface 7b of the lower edge 7 of the opening (see FIG. 1). That is, the support base 30 inserts the locking surface portion 32b of the locking plate portion 32 into the opening 7a from above and covers the front upper corner of the opening lower edge 7, and also locks the locking claw portion 34 with the locking hole. By engaging with the opening lower edge 7c, the front lower surface 7b of the opening lower edge 7 is engaged and supported by the opening lower edge 7 while being sandwiched from above and below.

  In addition, a linear rod-shaped rotating lever 37 is protruded forward from the locking claw portion 34. The rotation lever 37 is an operation part for rotating the locking claw part 34 around the pivot support part 35 to engage and release the support base 30 with the opening lower edge 7. The rotation lever 37 is fixed to the locking claw portion 34 and the support plate portion 36 by welding or the like, and together with the locking claw portion 34 and the support plate portion 36, an integrated rotation supported by the shaft support portion 35 is provided.

  When the support base 30 is fixed to the lower edge 7 of the opening, the support base 30 inserts the locking surface 32b from above into the opening 7a and covers the front upper corner of the lower edge 7 of the opening. The rotating lever 37 is operated downward. As a result, in a left side view (see FIG. 9), the integral rotating body supported by the shaft support 35 rotates counterclockwise, and the locking projection 34b of the locking claw 34 moves upward, A state where the support base 30 sandwiches the front surface 7b of the lower edge 7 of the opening, that is, a state where the support base 30 is engaged and fixed, is obtained.

  On the other hand, when the fixing of the support base 30 to the opening lower edge 7 is released, the rotating lever 37 is operated upward. Thereby, in a left side view (see FIG. 9), the integral rotating body supported by the shaft support 35 rotates clockwise, and the locking projection 34 b of the locking claw 34 moves downward, The state in which the front base 7b of the opening lower edge 7 is held by the support base 30, that is, the state in which the support base 30 is engaged and fixed is released. In a state in which the engaged and fixed state is released, the support base 30 can be removed from the lower edge 7 of the opening. Thus, the support base 30 is detachably fixed to the opening lower edge 7 of the vehicle body 2.

  In the support base 30 which is detachably fixed to the vehicle body 2 as described above, the lower support 12 is provided at the upper front corner, that is, the corner formed by the base plate 31 and the locking plate 32. A support shaft support portion 38 that rotatably supports the lower rotation support portion 12c is provided. Similarly to the inter-support member support portion 13, the support member support portion 38 has the vehicle left-right direction as the rotation axis direction.

The support cylindrical portion 38a is a cylindrical portion having substantially the same diameter as the lower rotation support portion 12c, and is supported by welding or the like via an L-shaped support plate 38b along the front upper corner of the support base 30. 30 is fixed to the main body. The support shaft support portion 38 rotatably supports the lower rotation support portion 12c by a support shaft portion 38c penetrating the lower rotation support portion 12c and the support cylinder portions 38a on both sides thereof.

  In this manner, the lower end of the support 10 constituting the vehicle opening / closing jig 1 is rotatably supported by the support shaft support 38 on the support base 30 fixed to the opening lower edge 7 of the vehicle body 2. Is done. That is, the support 10 is rotatably supported by the vehicle body 2 via the support base 30. The position of the support shaft support portion 38 in the support base 30 is fixed. Therefore, the support position of the lower end portion of the support portion 10 by the support shaft support portion 38 is a position fixed to the vehicle body 2 regardless of the opening / closing operation of the luggage door 3 and the accompanying operation of the vehicle opening / closing jig 1. Becomes

  The configuration for rotatably supporting the lower end of the lower support 12 is not limited to the present embodiment. For such a configuration, any configuration may be used as long as the lower end of the lower support 12 is rotatably supported at a predetermined position in the same rotation axis direction as the inter-support shaft support 13. Further, in the present embodiment, the opening 7a for providing the lock mechanism of the luggage door 3 is used as an opening for fixing the support base 30 to the vehicle body 2, but the opening 7a is not limited to this. The opening for fixing the support base 30 may be another existing opening or an opening dedicated to mounting the support base 30.

And stands up (see FIG. 1). In other words, in the door support state, the lower support 12 extends slightly upward from the support shaft support 38 toward the front of the vehicle, and the upper support 11 slightly extends from the inter-support shaft support 13 in the door support state. , And extends upward.

  On the other hand, in a state where substantially the entire vehicle opening / closing jig 1 is housed in the luggage room 4 and the luggage door 3 is substantially closed, the upper support 11 and the lower support 12 are separated from each other in a vehicle side view. The vehicle is bent toward the front of the vehicle so as to be substantially overlapped with each other and folded (see FIG. 2). In this state, the upper support 11 and the lower support 12 extend downward from the support portions opposite to the inter-support shaft support portions 13 toward the front lower side of the vehicle.

  When the luggage door 3 is substantially closed, the grip arm 24 is exposed to the outside through a gap between the luggage door 3 and the lower edge 7 of the opening while the grip portion 24b faces downward. When the arm portion 24a of the gripping arm 24 contacts the lower edge 7 of the opening, the luggage door 3 is supported in a slightly opened state. Hereinafter, the state in which the vehicle opening / closing jig 1 is stored and folded in the luggage room 4 with the luggage door 3 substantially closed is referred to as a “folded state”.

  Next, the support mechanism 40 will be described. The support mechanism 40 has a holding plate 41 as a swing holding body and a holding rod 42 as a locking holding part. The support mechanism 40 restricts the rotation of the lower support 12 with respect to the support base 30 by the holding plate 41 and the holding rod 42, thereby supporting the luggage door 3 together with the support 10 in an open state.

  In the present embodiment, the support mechanism 40 has a position where the upper support 11 and the lower support 12 are pivotally connected to each other on the front side of the vehicle with respect to the rotational support position of the lower support 12 with respect to the support base 30. The luggage door 3 is supported together with the support 10 in the bent state of the support 10. That is, in the vehicle opening / closing jig 1 in a state in which the door is supported by the support 10 and the support mechanism 40, the support 10 is an inter-support shaft which is a rotational connection position of the upper support 11 and the lower support 12. The support member support shaft 15 of the support portion 13 is bent in the front-rear direction of the vehicle with respect to the support shaft support portion 38, which is the rotation support position of the lower support member 12, in the front-rear direction of the vehicle.

  The holding plate 41 is supported at a position on the support side of the luggage door 3, that is, at a position on the front side of the vehicle (left side in FIG. 9) with respect to the support shaft support portion 38, which is the rotation support position of the lower support 12 with respect to the support base 30. The body 12 is rotatably suspended and supported. The holding plate 41 has a plate body 43 which is a plate-shaped portion as a swing base, and has a locking projection 45, a guide plate 46, and a stopper provided integrally with the plate body 43. It has a plate portion 47.

  The plate main body 43 has a narrow portion 43a which is a relatively narrow and long portion, and a relatively wide portion 43b provided at one longitudinal end of the narrow portion 43a. , These parts constitute a plate-like part having an external shape of a substantially elongated “L” shape. In the plate main body 43, the narrow portion 43a is gradually narrowed from one end (the wide portion 43b side) to the other end in the longitudinal direction, and has a substantially elongated triangular shape.

  The holding plate 41 is supported rotatably (swingably) with respect to the lower support 12 by supporting the plate body 43 on a plate shaft support 50 provided on the lower support 12. That is, the holding plate 41 is rotatably supported by the lower support 12 via the plate shaft support 50. The narrow end portion of the narrow portion 43a of the plate main body 43 is supported by the plate shaft support portion 50 in a state where the narrow front end portion is supported by the shaft. The holding plate 41 is supported in a direction in which the plate surface of the plate main body 43 is perpendicular to the left-right direction, and in which the protruding side of the wide portion 43b of the plate main body 43 is the front side. In the holding plate 41, the plate surface on the left side of the plate body 43 is a support plate surface 43c on which the locking projection 45, the guide plate 46, and the stopper plate 47 are provided.

  The plate shaft supporting portion 50 is provided on a side closer to the support base side (the support shaft supporting portion 38 side) of the lower support main body portion 12a of the lower support 12 and on the front side in the door supporting state. The plate shaft support 50 has a vehicle left-right direction as a rotation axis direction. The plate shaft support 50 has a pair of parallel support pieces 52 provided on the lower support body 12a of the lower support 12 via a rectangular plate-like support plate 51. The support piece 52 is a rectangular plate-like portion protruding from the support plate 51, and the pair of support pieces 52 face each other in the left-right direction.

  As shown in FIG. 8, the plate shaft supporting portion 50 has the distal end portion 43 d of the narrow portion 43 a of the plate main body 43 positioned between the pair of support pieces 52, and is bridged between the pair of support pieces 52. The plate body 43 is rotatably supported by the plate support shaft 53. The plate support shaft 53 includes a bolt, a nut, and the like, penetrates the pair of support pieces 52 and the distal end 43 d of the plate main body 43, and supports the plate main body 43. For this reason, a through-hole 43 e that allows the plate support shaft 53 to penetrate is formed in the distal end 43 d of the plate main body 43. The plate support shaft 53 is provided to be rotatable relative to at least one of the plate body 43 and the support piece 52.

  With such a configuration, the plate shaft support 50 supports the holding plate 41 so as to be rotatable with respect to the lower support 12 with the axial direction of the plate support shaft 53 as the rotation axis direction. Therefore, when the holding plate 41 is not subjected to an external action such as contact with other members, the holding plate 41 rotates with respect to the lower support 12 with the rotation of the lower support 12 by the support shaft support 38. It rotates relatively and keeps its hanging state under its own weight. The configuration of the supporting portion of the holding plate 41 with respect to the lower support 12 is not limited to the present embodiment. As a configuration of such a supporting portion, any configuration may be used as long as the holding plate 41 is rotatably supported with respect to the lower support 12 with the left-right direction being the rotation axis direction.

  As shown in FIG. 10, the locking projection 45 is a portion that constitutes a holding rod locking portion 44 serving as a locking portion with respect to the holding rod 42, and in the holding plate 41, the support plate surface 43 c of the plate body 43. It is projected. The locking protrusion 45 is provided below the narrow portion 43a of the plate body 43. The locking projection 45 protrudes vertically from the support plate surface 43c so as to form a substantially triangular shape in a plate surface view (left side view) of the support plate surface 43c of the plate body 43.

  The locking projection 45 has a rear plate portion 45a, a front plate portion 45b, and a lower plate portion 45c as plate-like portions that form triangular sides in a side view. These plate portions have a common projecting dimension from the support plate surface 43c. The rear plate portion 45a is provided along the rear side of the plate body portion 43 in a side view. The front side plate portion 45b is connected to the upper end of the rear side plate portion 45a on the front side of the rear side plate portion 45a, and forms an acute angle corner together with the rear side plate portion 45a in a side view. The lower plate portion 45c is a portion connecting the lower ends of the rear plate portion 45a and the front plate portion 45b.

  The locking protrusion 45 has a protruding plate portion 45d which is a portion extending below the front plate portion 45b. The protruding piece plate portion 45d is a portion forming a flat plate portion integral with the front plate portion 45b, and the lower plate portion 45c is connected to the flat plate portion substantially vertically. A corner portion formed by the protruding piece plate portion 45d and the lower plate portion 45c becomes a holding rod locking portion 44. In other words, the holding rod locking portion 44 is a lower outer angle portion with respect to an inner angle portion formed by the front plate portion 45b and the lower plate portion 45c which form a triangular shape together with the rear plate portion 45a in a side view.

  The holding rod 42 projects from the support base 30 to the front side of the vehicle, and is locked by a holding rod locking part 44 provided on the holding plate 41, so that the holding plate 41 supports the lower support 12. Hold the luggage door 3 open. The holding rod 42 is provided on the base plate 31 constituting the support base 30 via a support stay 48.

  The support stay 48 is formed by a bent plate-like member having a substantially “L” shape, and includes a fixed plate portion 48 a along the front surface 31 a of the base plate portion 31 and a bent portion that is substantially perpendicular to the fixed plate portion 48 a. And a support plate portion 48b protruding forward from the front surface 31a of the base plate portion 31. The support plate portion 48b has its plate surface perpendicular to the left-right direction. The bent plate-shaped member constituting the support stay 48 is fixed to the base plate portion 31 by welding or the like in a state where the plate surface opposite to the bent side of the plate-shaped portion to be the fixed plate portion 48a is in contact with the front surface 31a. Is done. The holding rod 42 is fixed to the support stay 48 on the left plate surface 48c of the support plate portion 48b by welding or the like.

  The holding rod 42 is formed of an L-shaped bent rod-shaped member. One side of the L-shape is a fixed rod 42a fixed to the support stay 48, and the other side is a holding rod. The locking rod portion 42b engages with the locking portion 44. The holding rod 42 extends the axial direction of the fixing rod 42a substantially in the front-rear direction (slightly upwardly inclined direction), the axial direction of the locking rod 42b in the left-right direction, and the locking rod 42b. To the right.

  The holding rod 42 engages with the holding rod locking part 44 with the locking projection 45 placed on the locking rod part 42b, and supports the holding plate 41. The holding rod 42 supports the holding plate 41 in a state where the locking rod 42b is inserted from the left side into a corner portion formed by the lower plate part 45c and the protruding piece part 45d as the holding rod locking part 44. (See FIG. 5).

  The holding rod 42 supporting the holding plate 41 in this manner is provided with respect to each part of the holding plate 41 in the left-right direction (the axial direction of the locking rod portion 42b) in the following positional relationship. That is, the holding rod 42 positions the tip of the locking rod 42b on the left side of the support plate surface 43c so that the locking rod 42b does not interfere with the plate body 43 of the holding plate 41. . In addition, the holding rod 42 is configured such that the distal end of the locking rod 42 b is brought into contact with the locking projection 45 of the holding plate 41 so that the locking rod 42 b is in contact with the locking projection 45. 45e on the right side.

  As described above, the holding rod 42 includes the locking rod 42b as a rod-shaped locking main body having the rotation axis direction of the holding plate 41 as the axial direction. That is, the holding rod 42 is connected to the holding rod 42 b, which is a rod-shaped part whose axial direction (longitudinal direction) is the left-right direction that is the rotation axis direction of the plate shaft support 50 that supports the holding plate 41. It is provided as a locking portion for the stopping portion 44.

  The holding rod 42 is locked by the holding rod locking part 44 by bringing the outer peripheral surface 42c of the locking rod part 42b into contact with the holding rod locking part 44. Specifically, as shown in FIG. 10, the holding rod 42 is configured such that the outer peripheral surface 42c of the locking rod part 42b is formed by the lower surface 45f of the lower plate part 45c and the protruding piece plate part 45d constituting the holding rod locking part 44. In a state in which it is in contact with the rear surface 45g, it is locked by the holding rod locking portion 44.

  As described above, the locking rod portion 42b of the holding rod 42 is locked by the holding rod locking portion 44, so that the holding plate 42 is supported by the holding rod 42. Such a state corresponds to the door supporting state of the vehicle opening / closing jig 1. In the door support state, the lower support 12 extending forward and upward from the support shaft support 38 is supported by the holding plate 41 supported by the holding rod 42. That is, in the door supporting state, the lower support 12 is supported via the holding plate 41 by the holding rod 42 which is a portion extending from the support base 30 fixed to the vehicle body 2. Therefore, in the door supporting state, the holding plate 41 supports the support portion 10 in the bent upright state in a manner sandwiched between the lower support 12 and the holding rod 42.

  In the door support state, the support mechanism 40 restricts the pivoting operation of the support 10 receiving the load from the luggage door 3 in the folding direction by the inter-support shaft support 13. Here, the folding direction of the support portion 10 by the inter-support shaft supporting portion 13 is the turning direction of the upper support 11 and the lower support 12 regulated by the support mechanism 40 in the door supporting state. This is a direction in which the upper support 11 and the lower support 12 close from each other so as to reduce the angle formed therebetween.

  The configuration for supporting the support 10 via the holding plate 41 is not limited to the holding bar 42 having the locking bar 42b as the locking main body. That is, the configuration for supporting the support portion 10 via the holding plate 41 is provided on the support base 30 and locked by the holding rod locking portion 44 so that the lower support 12 is attached to the holding plate 41. The configuration is not limited as long as it is supported and the luggage door 3 is kept open.

  In addition, the holding rod 42 has the following positional relationship with the plate shaft support 50 that supports the holding plate 41. That is, as shown in FIG. 9, in a side view of the vehicle opening / closing jig 1, a circle centered on a rotation center O <b> 1 of a support shaft support portion 38 which is a rotation support portion of the support portion 10 with respect to the support base 30. With respect to the circumference, the holding rod 42 exists inside the circumference S1 passing through the rotation center O2 of the plate shaft support 50 which is the rotation fulcrum of the holding plate 41. Here, the rotation center O1 of the support shaft support 38 corresponds to the position of the center axis of the support shaft 38c, and the rotation center O2 of the plate support 50 corresponds to the position of the center axis of the plate support shaft 53. I do.

  In other words, in a side view of the opening / closing jig 1 for a vehicle, the radius of the circumference S1 among the circumferences centered on the rotation center O1 is L1, and the radius of the circumference S2 passing through the outermost position P1 of the holding rod 42. Is L2, the relationship of L1> L2 is satisfied. As described above, the position of the rotation fulcrum (the rotation center O2) of the holding plate 41 is located outside the holding rod 42 with respect to the rotation radius of the support shaft support 38 around the rotation center O1.

  As shown in FIG. 9, in the vehicular opening / closing jig 1 in the door-supported state, the rotation center O2 of the plate shaft support 50 is larger than the rotation of the support shaft 38 than the locking bar 42 b of the holding bar 42. It is located near the moving center O1. That is, in the door supporting state, the rotation center O2 of the plate shaft support 50 is located rearward of the locking rod 42b. Therefore, in the front-rear direction, there is a difference in the position of the dimension X1 between the front end position of the holding rod 42 and the position of the rotation center O2 of the plate shaft support 50 located behind the holding rod 42. The dimension X1 is, for example, about 30 to 40 mm.

  The positional relationship between the rotation fulcrum of the holding plate 41 and the holding rod 42 is such that the holding plate 41 is moved by its own weight during the operation of the vehicle opening / closing jig 1 from the folded state to the door supporting state. It is intended to move to an engagement position (opening holding position) with respect to.

  Next, the guide plate 46 and the stopper plate 47 of the holding plate 41 will be described. In the following description, with respect to the longitudinal direction of the holding plate 41, the rotation support side of the plate body 43, that is, the tip side (upper side in FIG. 10) of the narrow portion 43a is defined as the upper side, and the opposite side, that is, the wider side. The portion 43b side (the lower side in FIG. 10) is defined as the lower side.

  First, the guide plate 46 will be described. The guide plate portion 46 moves the holding rod 42 relative to the holding plate 41, and when the holding rod 42 is locked to the holding rod locking portion 44, the holding rod locking portion 44 of the locking rod portion 42b. Act as a guide portion for guiding the movement to the locking position with respect to.

  The holding rod 42 is fixed to the support base 30 fixed to the vehicle body 2 and is at a fixed position with respect to the vehicle body 2. On the other hand, the holding plate 41 moves while rotating relative to the lower support 12 with the movement of the plate support 50 due to the rotation of the lower support 12 in the opening and closing operation of the luggage door 3. With respect to the relative movement of the holding rod 42 with respect to the holding plate 41 moving in this manner, the guide plate 46 guides the holding rod 42 to the holding rod locking part 44.

  The guide plate portion 46 is a rectangular plate-shaped protruding portion protruding perpendicular to the support plate surface 43c of the plate main body 43. The guide plate portion 46 is a portion which receives the contact of the locking bar portion 42b of the holding bar 42, and has a projection dimension from the support plate surface 43c substantially equal to that of the locking projection portion 45.

  The guide plate 46 is provided at a position below the locking projection 45. The guide plate portion 46 is provided so as to be inclined such that the front side is the upper side and the rear side is the lower side. The guide plate portion 46 has a rear plate surface serving as a guide surface 46a that comes into contact with the locking rod portion 42b of the holding rod 42.

  The guide plate portion 46 is provided in the following positional relationship with respect to the locking projection 45 and the locking bar portion 42b of the holding bar 42. As shown in FIG. 10, in a side view of the opening / closing jig 1 for the vehicle, with respect to the circumference around the rotation center O <b> 2 of the plate shaft support 50 serving as the rotation fulcrum of the holding plate 41, The difference ΔY between the radius of the circumference C1 passing through the vertex T1 of the corner portion formed by the rear plate portion 45a and the lower plate portion 45c and the radius of the circumference C2 passing through the upper vertex T2 of the guide plate portion 46 is a holding rod. The size is set to be slightly smaller than the outer diameter of the locking bar portion 42b. In other words, the guide plate 46 is provided at a position where the gap defined as the difference ΔY is slightly smaller than the outer diameter of the locking rod 42 b of the holding rod 42 in relation to the locking projection 45. ing. Specifically, the difference ΔY is set, for example, to a size smaller by about 2 mm than the outer diameter of the locking rod 42b.

  The size of the gap between the locking projection 45 and the guide plate 46 is such that the holding plate 41 that rotates rearward during the operation of the vehicle opening / closing jig 1 that changes from the folded state to the door supporting state. This is to ensure that the locking rod portion 42b abuts on the guide surface 46a of the guide plate portion 46 to reliably obtain the guiding action by the guide plate portion 46. For example, when the clearance between the locking projection 45 and the guide plate 46 is larger than the outer diameter of the locking rod 42b, the relative position of the holding rod 42 with respect to the holding plate 41 that rotates rearward. During the movement, the locking bar portion 42b may pass through the locking projection 45 without engaging with the holding bar locking portion 44. Therefore, by setting the difference ΔY to be smaller than the outer diameter of the locking rod portion 42b, the locking rod portion 42b passes through the open holding position, that is, the engagement position with the holding rod locking portion 44. Is reliably prevented. The distance between the apex T1 and the apex T2 in a side view of the vehicle opening / closing jig 1 is determined by the distance between the apexes T1 and T2. Larger than the outer diameter.

  Next, the stopper plate 47 will be described. The stopper plate part 47 moves the holding rod 42 with respect to the holding plate 41, and after the locking rod part 42 b is out of the locking position with respect to the holding rod locking part 44, the locking rod part 42 b moves to the holding plate 41. Acts as a stopper for restricting movement outside the range.

  The stopper plate portion 47 is a rectangular plate-shaped protruding portion projecting perpendicularly to the support plate surface 43c of the plate body portion 43, similarly to the guide plate portion 46. The stopper plate portion 47 is a portion which receives the contact of the locking bar portion 42b of the holding bar 42, and has a projection dimension from the support plate surface 43c substantially equal to that of the locking projection portion 45.

  The stopper plate portion 47 is provided at a position in front of the protruding piece plate portion 45 d of the locking protrusion 45. The stopper plate portion 47 is provided so as to face the up-down direction substantially so as to face the protruding plate portion 45d. More specifically, the stopper plate portion 47 is provided above the wide portion 43b of the plate body portion 43 along the inclination of the front side of the narrow portion 43a in a left side view. The stopper plate portion 47 has a rear plate surface as a stopper surface 47a that comes into contact with the locking rod portion 42b of the holding rod 42.

  The support mechanism 40 having the above-described configuration allows the holding rod 42 to move relative to the holding plate 41 due to the relative movement of the holding rod 42 with respect to the holding plate 41 in accordance with the opening / closing operation of the luggage door 3. The locking to the stopping portion 44 and the release of the locking are alternately performed.

  The operation of the vehicle opening / closing jig 1 according to the present embodiment will be described with reference to FIGS. 11, 12, and 13. FIG. 11, 12 and 13 are explanatory views of the operation of the vehicle opening / closing jig 1.

  In the description of the operation of the vehicle opening / closing jig 1, the operation from the folding state to the door supporting state of the vehicle opening / closing jig 1 includes the operation of opening the luggage door 3 in a substantially closed state. "Opening operation". In addition, the operation from when the vehicle opening / closing jig 1 is changed from the door supporting state to the folding state is referred to as “closing operation” because such operation involves the operation of closing the luggage door 3 in the opened state. In the opening operation and the closing operation, the up / down operation (opening / closing operation) of the luggage door 3 is performed by an operation of the gripping arm 24 by an operator or a robot.

  First, the opening operation of the vehicle opening / closing jig 1 will be described. In the vehicle opening / closing jig 1 in a folded state before performing the opening operation, as shown in FIG. 11A, the support body 10 is folded forward and the holding plate 41 is moved forward with respect to the holding rod 42. Present at a remote location.

  In the opening operation of the vehicle opening / closing jig 1, the substantially closed state of the luggage door 3 (see FIG. 2) is rotated (lifted) in the opening direction so that the luggage door 3 and the door-side support portion 20 are moved upward. The support main body 11a is pulled up (see the arrow A1 in FIG. 11A). Thereby, the vehicle opening / closing jig 1 in the folded state is opened as shown in FIG. 11B.

  In the process of opening the vehicle opening / closing jig 1 from the folded state, the plate support 50 moves upward and rearward as the lower support 12 rotates in the rising direction (the right rotation direction in FIG. 11A). At the same time, the holding plate 41 also moves rearward and upward. Then, at a predetermined timing in the process of rotating the lower support 12, the holding plate 41 collides with the locking rod portion 42b of the holding rod 42 as shown in FIG. 12A (see arrow B1). The locking bar portion 42b here is indicated by 42b (p1). More specifically, the locking rod 42b of the holding rod 42 collides with the rear surface 45h of the rear plate 45a of the locking projection 45 of the holding plate 41. Thus, the rearward movement of the holding plate 41 is restricted by the holding rod 42 in contact with the rear surface 45h of the locking projection 45.

  After the locking rod portion 42b collides with the locking protrusion 45, the holding plate 41, which continuously rises due to the opening operation of the luggage door 3, is in a state in which backward movement is restricted for a predetermined period, that is, the locking protrusion The state where the locking bar portion 42b is in contact with the rear surface 45h of the portion 45 is maintained. In this period, as shown in FIG. 12A, the locking rod portion 42b in contact with the rear surface 45h moves downward along the rear surface 45h relative to the rising holding plate 41. (See arrow B2). The locking bar portion 42b here is indicated by 42b (p2). In each of FIGS. 12A and 12B, the relative movement of the locking rod 42b with respect to the holding plate 41 that moves with respect to the vehicle body 2 in the operation of the vehicle opening / closing jig 1 is shown.

  That is, as shown in FIG. 13A, the holding plate 41 contacts the locking rod 42b with the upper part of the rear surface 45h of the locking projection 45, and then maintains the contact state of the locking rod 42b. Then, as shown in FIG. 13B, the locking rod 42b is brought into contact with the lower portion of the rear surface 45h of the locking projection 45.

  When the luggage door 3 reaches a predetermined open position, the holding plate 41 rises, so that the locking bar 42b passes the rear surface 45h of the locking protrusion 45, and the restriction of the rearward movement of the holding plate 41 is released. . As a result, as shown in FIG. 12A, the holding plate 41 rotates rearward, collides with the locking rod 42b on the guide surface 46a of the guide plate 46, and moves backward again (rotation). Movement) is restricted (see arrow B3). The locking rod portion 42b here is indicated by 42b (p3).

  That is, as shown in FIG. 13B, the holding plate 41 further rises from a state in which the locking rod 42b is in contact with the lower part of the rear surface 45h of the locking projection 45, and the rearward of the locking projection 45. When the regulation of the pivoting movement is released, the body pivots rearward, and the locking rod portion 42b is brought into contact with the guide plate portion 46 as shown in FIG. 13C. The temporary stop position of the holding plate 41 caused by the holding plate 41 contacting the locking bar portion 42b with the guide plate portion 46 is referred to as a “temporary fixing position”.

  After the holding plate 41 has reached the temporary fixing position, the luggage door 3 is rotated in a slightly closing direction (downward), thereby causing the holding plate 41 to rotate rearward as shown in FIG. As a result, the locking rod portion 42b relatively moves from the state in which it comes into contact with the guide plate portion 46 to the locking position (open holding position) with respect to the holding rod locking portion 44 (see arrow B4). The locking rod portion 42b here is indicated by 42b (p4).

  That is, the holding plate 41 is lowered from a state in which the locking rod 42b is in contact with the guide plate 46 as shown in FIG. 13C, and the restriction of the guide plate 46 from rotating backward is released. As a result, as shown in FIG. 13D, the lock rod 42b is locked to the holding rod locking part 44 so that the locking rod 42b is locked to the holding rod locking part 44.

  As described above, the guide plate portion 46 once restricts the rotation of the holding plate 41 at the temporary fixing position by receiving the abutment of the locking rod portion 42b in the opening operation of the vehicle opening / closing jig 1, and holds the holding plate 41. With respect to the relative movement of the rod 42 with respect to the holding plate 41, the locking rod portion 42b is guided to the locking position by the holding rod locking portion 44. The state in which the locking bar portion 42b is locked to the holding bar locking portion 44 is the door supporting state of the vehicle opening / closing jig 1 shown in FIGS. 1 and 11B.

  In other words, as shown in FIG. 11C, when the holding plate 41 is raised, the locking bar 42b is moved relative to the holding plate 41 by the holding rod 42b. , And gets over the projecting plate portion 45d. As a result, as shown in FIG. 12C, the holding plate 41 rotates backward, collides with the locking rod 42b at the stopper surface 47a of the stopper plate 47, and temporarily moves backward ( (Rotation) is restricted (see arrow B5). The locking rod portion 42b here is indicated by 42b (p5).

  That is, as shown in FIG. 13D, the holding plate 41 is locked by rising from a state in which the locking rod 42b is locked to the holding rod locking part 44 (a state in the open holding position). The rod portion 42b is detached from the holding rod locking portion 44, and the locking rod portion 42b is brought into contact with the stopper plate portion 47 as shown in FIG.

  As described above, the stopper plate portion 47 is related to the relative movement of the locking bar portion 42b with respect to the holding plate 41 in the closing operation of the vehicle opening / closing jig 1, after the locking bar portion 42b comes off the locking position. This restricts the locking bar 42b from moving out of the range of the holding plate 41, that is, to a position outside the plate body 43.

  Then, by closing the luggage door 3 from the state in which the locking bar portion 42b is in contact with the stopper plate portion 47, the locking bar 41 is moved downward of the holding plate 41 as shown in FIG. The portion 42b relatively moves upward along the front plate portion 45b of the locking projection 45 (see arrow B6). The locking rod portion 42b here is indicated by 42b (p6).

  That is, the holding plate 41 is lowered from the state in which the locking rod portion 42b is in contact with the stopper plate portion 47 as shown in FIG. 13E, and the locking projection 45 as shown in FIG. The locking bar portion 42b is located on the front side of the front side plate portion 45b.
