  Here, each of the bumper side engaging portions 20 is formed one step lower than the surface of the flange 19 by the step portions 21 on both sides (a direction away from the bent wall 17 of the side panel 4 than the flange 19). A hole 22 formed between the front bumper 2 and the back surface of the front bumper 2 is formed at a position separated from the back surface of the front bumper 2. In the bumper side engaging portion 20, an engaging claw 23 is erected toward the bent wall 17 of the side panel 4. The step portion 21 connects the bumper side engaging portion 20 to the flange 19, and similarly to the hole 22 formed between the back surface of the front bumper 2 and the bumper side engaging portion 20, the bumper side engaging portion 20. It has a function of facilitating elastic deformation.

  Further, as shown in FIGS. 3, 9, and 10, the bumper holder 5 is integrally formed of resin as a lattice-like member that opens toward the outer side of the vehicle body (the front side of FIG. 3). As shown in FIG. 6, a plurality of (three in the present embodiment) engagement holding portions 24 are erected integrally at an appropriate interval in the longitudinal direction (the longitudinal direction of the vehicle body). An abutment prevention portion 25 is integrally provided on both sides. A vertical rib-shaped positioning portion 26 is integrally provided on the side of each contact prevention portion 25 at the top of the bumper holder 5, and the longitudinal direction of each engagement holding portion 24 at the top of the bumper holder 5. Similarly, a longitudinal rib-shaped support portion 27 is erected integrally with the intermediate portion toward an engagement hole 29a described later.

  Here, each of the engagement holding portions 24 is a rectangular plate-like vertical wall portion 28 that stands up substantially vertically from the upper surface wall of the bumper holder 5, and from the upper end of the vertical wall portion 28 toward the outside of the vehicle body. The holder side engaging portion 29 that extends integrally is formed, and in the center of the holder side engaging portion 29, a substantially rectangular engagement that engages with the engaging claw 23 of the bumper side engaging portion 20 of the front bumper 2. A hole 29a is formed. Therefore, the holder-side engaging portion 29 is formed in a thin frame shape and has low rigidity, and can be elastically deformed. The engagement hole 29a is formed in a size that allows the engagement claw 23 of the bumper side engagement portion 20 to be inserted. The edge on the opposite side of the vertical wall portion 28 of the engagement hole 29a is on the bumper side.

In addition, you may chamfer the front-end | tip lower edge of the holder side engaging part 29 so that the engaging claw 23 of the bumper side engaging part 20 can be easily inserted in the engaging hole 29a.

  The vertical wall portion 28 supports the holder-side engagement portion 20, and a rectangular recess 28 a is formed at the center of the back surface thereof, and the vertical wall portion 28 has vertical directions on both sides. The slit 30 is formed. Accordingly, the vertical wall portion 28 is configured such that the thickness of the central portion is reduced by the recess 28a and the rigidity is lowered, and the vertical wall portion 28 is configured to be easily elastically deformed together with the effect of the slit 30. As a result of forming the rectangular recess 28a in the center of the back surface of the vertical wall portion 28, a thick portion is formed around the recess 28a of the vertical wall portion 28 in a rectangular frame shape. Since the frame-shaped part and the frame-shaped part of the holder side engaging part 29 are connected, the connecting part of the vertical wall part 28 and the holder side engaging part 29 is firmly integrated. In addition, you may form the hollow 28a with a through-hole similarly to the engagement hole 29a.

  The upper end of the vertical wall portion 28 protrudes above the holder side engaging portion 29 (the bent wall 17 side of the side panel 4) to form a tool abutting portion 28b. The tool abutting portion 28b And a contact surface facing outward of the vehicle body.

  Further, as shown in FIG. 10, the contact prevention portion 25 is located between the flange 19 of the front bumper 2 and the bent wall 17 of the side panel 4 to prevent the front bumper 2 from contacting the side panel 4. It is formed so as to be thinner than other parts of the bumper holder 5 so as to be elastically deformable, and can be bent in accordance with the bending wall 17. The contact prevention portion 25 includes a rising portion 25a that stands up substantially vertically from the upper surface wall of the bumper holder 5, and a tongue-like spacer portion that extends substantially perpendicularly from the upper end of the rising portion 25a toward the outside of the vehicle body. 25b.

  As shown in FIG. 10, the spacer portion 25b is positioned between the flange 19 of the front bumper 2 and the bent wall 17 of the side panel 4 to determine the position of the front bumper 2 relative to the side panel 4, and between the two ( The function of improving the appearance by keeping the parting dimension) constant, and the function of preventing the front bumper 2 from contacting the side panel 4 and preventing the side panel 4 from peeling off due to vibration or the like are achieved.

  Further, as shown in FIGS. 5 and 6, the positioning portion 26 has a stopper portion 26a and a support surface 26b, and functions to position the flange 19 of the front bumper 2 as will be described later.

  Further, the support portion 27 has a contact surface 27a that contacts the back surface (lower surface) of the bumper-side engagement portion 20 of the front bumper 2, and the bumper-side engagement engaged with the holder-side engagement portion 29 as will be described later. It functions to prevent the joint portion 20 from moving in the disengagement direction (the direction in which the overlapped engagement portions 20 and 29 are separated from each other).

  Thus, both side portions of the front bumper 2 are held by being fitted into the bumper holder 5 from the outside so as to cover the stepped portion 18 of the side panel 4 as shown in FIGS. That is, each bumper side engaging portion 20 of the front bumper 2 moves inward of the vehicle body while being guided by the support portion 27 of the bumper holder 5, and the engaging claw 23 is engaged with the holder side as shown in FIGS. By engaging with the engagement hole 29 a of the joint portion 29, the side portion of the front bumper 2 is held by the bumper holder 5. At this time, as shown in FIG. 9, the contact surface 27 a of the support portion 27 of the bumper holder 5 contacts the back surface (lower surface) of the bumper side engagement portion 20, and the bumper side engagement portion 20 moves downward. Therefore, the engagement of the front bumper 2 that is easily elastically deformed because the engagement claw 23 is prevented from coming off from the engagement hole 29a, and is made of a relatively soft material, is ensured. To be made.

  Further, as shown in FIG. 10, the spacer portions 25 b of the respective contact preventing portions 25 provided on the bumper holder 5 are located between the flange 19 of the front bumper 2 and the bent wall 17 of the side panel 4. Is positioned with respect to the side panel 4, and the front bumper 2 is prevented from coming into contact with the side panel 4, thereby preventing the peeling of the side panel 4 due to vibration or the like and the accompanying rust. Further, the spacer 25b keeps the gap (parting size) between the front bumper 2 and the bent wall 17 of the side panel 4 constant, and the appearance of the portion is enhanced.

  Further, the support surface 26b of the positioning portion 26 is in contact with the back surface (lower surface) of the flange 19 of the front bumper 2 and the tongue-shaped spacer portion 25b of the contact prevention portion 25 is located at the height position (side panel). 4) (position in the vertical direction with respect to the bent wall 17). Further, the stopper portion 26 a of the positioning portion 26 abuts on the front end of the flange 19 of the front bumper 2 and restricts the position of the front bumper 2 in the left-right direction of the vehicle body. The support surface 26b of the positioning portion 26 holds the flange 19 of the front bumper 2 from above and below together with the spacer portion 25b of the contact prevention portion 25, but the positioning portion 26 is displaced in the longitudinal direction with respect to the contact prevention portion 25. Since it is disposed at the position, some error of the support surface 26 b of the positioning portion 26 is allowed by the elasticity of the flange 19 of the front bumper 2.

  Thus, when both side portions of the front bumper 2 are engaged and held by the bumper holder 5 as described above, the bent wall 17 of the side panel 4 and the holder side engaging portion of the bumper holder 5 as shown in FIG. A space S in which the holder side engaging portion 29 can move toward the bent wall 17 side is formed between them.

  By the way, the front bumper 2 having both sides engaged and held by the bumper holder 5 by the above configuration can be easily removed from the bumper holder 5 by the following method when necessary for repair or the like.

  First, as shown in FIG. 11, the first method is to insert a thin plate-shaped tool 31 into the space S between the front bumper 2 and the side panel 4, and the tip of the tool 31 is a tool contact portion of the bumper holder 5. When the tool abutting portion 28b is pressed to the back side (right side in FIG. 11) against the surface 28b, the vertical wall portion 28 of the bumper holder 5 at the chain line position in FIG. 11 is deformed as indicated by a solid line. Since the holder side engaging portion 29 extending integrally from the vertical wall portion 28 moves in the direction of the arrow a in the space S, the engagement of the bumper side engaging portion 20 of the engaging hole 29a of the holder side engaging portion 29 is engaged. The engagement with the joint claw 23 is released, and the front bumper 2 can be easily removed from the bumper holder 5 without damaging the front bumper 2 or deteriorating the appearance quality.

  Thus, in the present embodiment, the recess 28a is formed in the vertical wall portion 28 erected on the bumper holder 5 and the slits 30 are formed on both sides of the vertical wall portion 28. Therefore, when removing the front bumper 2, the bumper holder If the tip of the tool 31 is applied to and pressed against the tool contact portion 28b of 5, the vertical wall portion 28 is easily elastically deformed, and the holder side engaging portion 29 supported by the vertical wall portion 28 is in the space S. It moves easily and disengages from the engaging claw 23 of the bumper side engaging portion 20, so that the front bumper 2 can be removed more easily.

  Further, if the tool 31 is inserted straightly between the vehicle body panel 4 and the front bumper 2 toward the inside of the vehicle body, the tip of the tool 31 comes into contact with the tool contact portion 28b of the bumper holder 5, so that the tool 31 can be easily inserted. In addition, the gap (parting size) between the side panel 4 and the front bumper 2 can be reduced to enhance the appearance.

  Furthermore, in the present embodiment, the bumper side engaging portion 20 is disposed in a direction away from the bent wall 17 of the side panel 4 rather than the flange 19 of the front bumper 2, and therefore, the bent wall 17 of the side panel 4 and the holder side engaging portion 29. A large space S can be secured between the holder S and the holder side engaging portion 29 can be accommodated in the space S, and the holder side engaging portion 29 is moved in the space S when the front bumper 2 is removed. Thus, the engagement between the holder side engaging portion 29 and the bumper side engaging portion 20 can be reliably released.

  By the way, as described above, the bumper side engaging portion 20 is placed on the side panel 4 more than the flange 19 of the front bumper 2 in order to secure a large space S between the bent wall 17 of the side panel 4 and the holder side engaging portion 29. When arranged away from the bent wall 17, defects in appearance such as sink marks are likely to occur on the design surface of the front bumper 2, but the bumper side engaging portion 20 is arranged away from the back surface of the front bumper 2, and the front bumper 2 Since the hole 22 is formed between the back surface and the bumper side engaging portion 20, the occurrence of defects such as sink marks can be prevented.

  Next, another method for removing the front bumper 2 will be described with reference to FIG.

  In the method shown in FIG. 12, the front bumper 2 is pulled in the direction indicated by the arrow b to form a gap δ between the front bumper 2 and the side panel 4, and a thin plate-like tool 31 is moved into the space S from the gap δ. The tool 31 is pushed down in the direction of arrow c with the upper end edge 2a of the front bumper 2 as a fulcrum. Then, the holder side engaging portion 29 that was in the position of the chain line in FIG. 12 is deformed as indicated by the solid line and moves in the direction of the arrow a in the space S. And the engagement claw 23 of the bumper side engagement portion 20 are released, and the front bumper 2 is removed from the bumper holder 5 without causing damage to the front bumper 2 or deterioration in appearance quality, as in the first method. It can be easily removed.

  Thus, in the present embodiment, since the hole 22 is formed between the back surface of the front bumper 2 and the bumper side engaging portion 20, the bumper side engaging portion 20 is given elasticity, and the front bumper 2 is attached to the semi-bent wall 17. The gap δ between the side panel 4 and the front bumper 2 can be increased so that the disengagement operation can be performed more easily. Then, the holder-side engagement portion 29 is released from the bent wall 17 side (bumper-side engagement portion 20) of the side panel 4 with the tool 31 inserted from the gap δ between the side panel 4 and the front bumper 2. The bumper side engaging portion 20 and the holder side engaging portion 29 are easily disengaged, and the front bumper 2 can be removed from the bumper holder 5 more easily.

  In the above, the mounting structure and the removal method of the front bumper 2 have been described in particular. However, the rear bumper 3 shown in FIG. 1 can be easily removed by the same method as the front bumper 2 by adopting the same mounting structure as the front bumper 2. it can.
