As shown in FIG. 1, the bumper face attaching portion 21 is covered with the bumper face 22 by attaching the bumper face 22. For convenience of explanation, the vehicle body 19 indicates a portion excluding the bumper face 22 of the vehicle.

  As shown in FIG. 2, the side edges 25 on both sides in the vehicle width direction of the bumper face mounting portion 21 have a stepped shape in which the front end edge portions 26 are lowered inward in the vehicle width direction from the outer appearance portion 27 of the side panel 20. In addition, the front end edge portion 26 has a shape that is inclined linearly so as to be positioned on the lower side as viewed from the vehicle width direction outer side.

  Bumper spacers 30 are attached by screwing or the like near the front end edge portion 26 of both side portions 25 of the bumper face attachment portion 21 so as to follow the front end edge portion 26, respectively. The bumper spacer 30 is made of synthetic resin, and a base portion 31 that forms a predetermined gap with the front end edge portion 26 of the bumper face mounting portion 21, and an oblique direction that is rearward and downward from the upper portion of the base portion 31. And a lower temporary holding portion 33 protruding rearward and downward from the lower portion of the base portion 31 in an oblique direction.

  The base portion 31 has a shape that the outer side in the vehicle width direction substantially follows the appearance portion 27 on the front end edge portion 26 side of the side panel 20, and as shown in FIG. 3, on the front end edge portion 26 side of the base portion 31. A mounting claw portion 35 is formed.

  As shown in FIG. 2, the upper temporary holding portion 32 has a substantially V shape so that the width becomes narrower toward the protruding tip when viewed from the outside in the vehicle width direction, and the protruding tip as a whole outwards in the vehicle width direction. The guide part 38 provided with the inclined surface 37 which inclines so that the side may be located inside a vehicle width direction is provided. A locking recess 39 that is recessed inward in the vehicle width direction is formed in the middle of the guide portion 38. Here, the base portion 31 side of the locking recess 39 is an inclined surface 40 positioned on the outer side in the vehicle width direction as the base portion 31 side.

  In addition, the upper temporary holding portion 32 has a locking claw 41 protruding upward from the guide portion 38 at the upper portion of the guide portion 38.

  The bumper face 22 is attached to the vehicle body 19 via bumper spacers 30 on both sides in the vehicle width direction, but the lower edge 14 of the side portion 13 of the rear combination lamp 12 is located on the lower side as it is closer to the rear side. The bumper face 22 disposed below the rear combination lamp 12 is formed along the lower edge 14 of the side portion 13 of the rear combination lamp 12 with the arrow shown in FIG. As shown by X, it is attached to the vehicle body 19 with the diagonal direction from the rear to the front and above as the attachment direction. As a result, the protruding direction of the upper temporary holding portion 32 and the lower temporary holding portion 33 of the bumper spacer 30 protrudes in the direction opposite to the mounting direction when the bumper face 22 is attached to the bumper face mounting portion 21. Therefore, the inclined surface 37 of the guide portion 38 of the upper temporary holding portion 32, the inclined surface 40 of the locking recess 39, the inclined surface 43 of the guide portion 44 of the lower temporary holding portion 33, and the inclined surface 46 of the locking recess 45 are: It inclines so that the position in a vehicle width direction may become an outer side along the attachment direction of a bumper face.

  The bumper face 22 attached so as to cover the bumper face attaching portion 21 is made of synthetic resin, and the front end edge portions 51 of the side portions 50 on both sides in the vehicle width direction are bumper faces as shown in FIG. Like the front end edge portion 26 of the attachment portion 21, it has a shape that inclines in a straight line so that the front side is located on the lower side. As shown in FIG. 3, the front end edge portion 51 is formed with an attachment portion (locking portion) 52 that protrudes toward the inside of the vehicle, and an attachment hole 53 is formed in the attachment portion 52. ing.

  In addition, since the lower end edge 14 of the side portion 13 on both sides in the vehicle width direction of the rear combination lamp 12 is inclined so as to be located on the lower side, the bumper face 22 is adjusted accordingly. As shown in FIG. 4, the upper end edge 55 that curves inward in the vehicle width direction of the side portions 50 on both sides in the vehicle width direction is inclined so that the rear side is located on the lower side. Each upper end edge 55 is formed with a locking hole 56 penetrating in the vertical direction at a predetermined position on the front end edge 51 side.

  In the bumper structure of the present embodiment, when the bumper face 22 is attached to the bumper face attaching portion 21, as described above, the lower end edge portion 14 of the side portion 13 of the rear combination lamp 12 is positioned on the lower side toward the rear side. Because of the inclined shape, the bumper face 22 disposed below the rear combination lamp 12 extends along the lower end edge 14 of the side portion 13 of the rear combination lamp 12 along the arrow X shown in FIG. Thus, the vehicle is attached to the vehicle body 19 side with the oblique direction from the rear to the front and above as the attachment direction.

  At this time, first, as shown in FIG. 5, the front end side of the inclined surface 43 of the guide portion 44 of the lower temporary holding portion 33 of the both bumper spacers 30 attached to the bumper face attaching portion 21 on the vehicle body 19 side, that is, the vehicle width. The side portion 50 of the bumper face 22 is pushed in from the side located inward in the direction, and although not shown in the drawing, at the same time, the side portion 50 of the inclined portion 37 of the guide portion 38 of the upper temporary holding portion 32 is located inward in the vehicle width direction. The side part 50 of the bumper face 22 will be pushed in from the side to do. Here, the positions of both inclined surfaces 43 in the vehicle width direction are gradually located outside along the mounting direction of the bumper face 22, and the positions of both inclined surfaces 37 in the vehicle width direction are also the mounting direction of the bumper face 22. Therefore, the mounting portion 52 of the side portion 50 of the bumper face 22 is pushed along the mounting direction of the bumper face 22 and the inclined surfaces 37 and 43 of these guide portions 38 and 44 are pushed. The bumper face 22 is slightly deformed so that the mounting portion 52 is positioned on the outer side in the vehicle width direction. At this time, the upper edge 55 of the bumper face 22 is moved above the locking claw 41 of the upper temporary holding portion 32 of the bumper spacer 30 in order to avoid interference.

  Then, when the mounting portion 52 of the bumper face 22 reaches the position of both locking recesses 39 and 45 in which the position in the vehicle width direction is on the inner side than before, as shown in FIG. While entering into the recess 45, although not shown, it also enters into the locking recess 39. At this time, the locking claw 41 of the bumper spacer 30 and the locking hole 56 of the bumper face 22 are aligned. Therefore, when the bumper face 22 is slightly lowered in this state, as shown in FIG. 4, the bumper face 22 is locked in a state where the locking claw 41 is inserted into the locking hole 56 from below. At this time, since the locking hole 56 is provided in the bumper face 22, the locking of the locking claw 41 to the locking hole 56 is easily visible.

  In the above state, the bumper face 22 is in front of the mounting direction on the vehicle body 19 side in the mounting direction, and is locked in the locking hole 56 to the locking claw 41 of the bumper spacer 30 on the vehicle body 19 side. In addition, a temporary holding state is achieved in which the mounting recess 52 formed on the inner side of the side portion 50 is locked to the locking recesses 39 and 45 on the vehicle body 19 side. In this temporary holding state, the swinging of the bumper face 22 is restricted. Is done. Therefore, the locking claw 41 engages the bumper face 22 in a state where the locking claw 41 is inserted from below into the locking hole 56 of the bumper face 22 in front of the mounting direction on the vehicle body 19 side. Stop.

  Then, the locking claw 41 is moved slightly upward so as to remove the locking claw 41 from the locking hole 56 with respect to the side portion 50 on one side in the vehicle width direction of the bumper face 30 temporarily held on the vehicle body 19 side in this way. Then, when the front and upper oblique directions are further pushed in as the mounting direction, the position of the inclined surface 46 of the locking recess 45 in the vehicle width direction gradually increases along the mounting direction of the bumper face 22 as shown in FIG. Since the position in the vehicle width direction of the inclined surface 40 of the locking recess 39 is gradually located along the mounting direction of the bumper face 22, the mounting direction of the bumper face 22 is determined. And the mounting portion 52 of the side portion 50 of the bumper face 22 is placed on the inclined surfaces 40 and 46 of the locking recesses 39 and 45 so that the bumper face 22 extends the mounting portion 52 in the vehicle width. It will be somewhat deformed so as to be positioned in the direction outward. Then, when the side portion 50 is further pushed in with the front and upper oblique direction as the attachment direction, the attachment portion 52 comes out of the locking recesses 39 and 45 and is placed on the outer surface of the pedestal portion 31 and finally shown in FIG. In this manner, the bumper spacer 30 is fitted into the gap between the bumper face mounting portion 21 and the front edge 26 of the bumper face mounting portion 21, and is engaged with the mounting claw portion 35 of the bumper spacer 30 through the mounting hole 53. Next, the side part 50 on either side of the bumper face 22 in the vehicle width direction is similarly attached.

  In the state where the bumper face 22 is attached to the bumper face attachment portion 21 as described above, that is, the state where the bumper face 22 is attached to the final attachment position, the upper edge 55 of the bumper face 22 is as shown in FIG. The rear combination lamp 12 enters the lower side of the lower end edge portion 14, and as a result, the locking hole 56 is covered with the rear combination lamp 12.

  According to the bumper structure of the present embodiment described above, the locking claw 41 formed on the vehicle body 19 side is inserted into the locking hole 56 formed on the upper side of the side portion 50 of the bumper face 22 during temporary holding. Since it is a structure to latch, the latching of the latching claw 41 to the latching hole 56 is easy to visually recognize. Therefore, the workability of temporarily holding the bumper face 22 can be improved, and as a result, the work efficiency of the entire bumper face 22 can be improved.

  Further, the bumper face 22 is locked to the locking claw 41 on the vehicle body 19 side in the locking hole 56, and the locking recesses 39 and 45 on the vehicle body 19 side are attached to the mounting portion 52 formed inside the side portion 50. By locking, the bumper face 22 can be reliably locked without swinging. Therefore, since the posture of the bumper face 22 is stabilized in the temporary holding state, the subsequent work efficiency can be improved.

  In addition, in a state where the bumper face 22 is attached to the final attachment position on the vehicle body 19 side, the rear combination lamp 12 on the vehicle body 19 side covers the locking hole 56, so that the appearance performance is not impaired. .

  Further, since the bumper face 22 is attached to the vehicle body 19 side with the mounting direction being obliquely upward, the workability of the attachment work is not particularly good, so the effect of improving the workability of the temporary holding of the bumper face 22 is very high. For example, it is possible to satisfactorily cope with an installation work by one worker.

  In the above embodiment, the bumper structure of the present invention is applied to the rear bumper. However, the bumper structure can be applied to a front bumper.
