  In view of the above facts, the present invention provides a bumper assembly structure that can easily position a bumper member such as a bumper cover and is inexpensive, and a bumper positioning structure manufacturing method in such an assembly structure. Is the purpose.

  The bumper assembly structure according to the first aspect of the present invention can be assembled to the support body by approaching the support body provided on the vehicle body side and the support body along a predetermined assembly direction. Cut from a contact portion extending from one of the bumper members toward the other side of the bumper, and a flat base provided on the other of the bumper members corresponding to the contact portion. A restriction that is formed by being raised and that restricts displacement of the contact part in a predetermined restriction direction that intersects with the assembly direction when the contact part comes into contact with the support member when the bumper member approaches. And a regulating means having a portion.

  In the bumper assembly structure according to the first aspect of the present invention, when the bumper member approaches the support body provided on the vehicle body side along the predetermined assembly direction, one of the support body and the bumper member is provided. The abutting portion extending from the second member approaches relatively to the restricting means provided on one of the other. When the abutting portion approaches the restricting means in this way, it abuts on the restricting portion formed at the base of the restricting means. In this way, the contact portion that has come into contact with the restricting portion is restricted by the restricting portion from being displaced in a predetermined restricting direction that intersects the assembly direction. The relative displacement of the bumper member is restricted, and the bumper member is positioned along this restriction direction.

  According to a second aspect of the present invention, there is provided the bumper assembly structure according to the first aspect of the present invention, wherein the base portion extends along a predetermined facing direction intersecting both the assembly direction and the regulating direction. And a retraction hole penetrating in the opposite direction and allowing a part of the contact portion to enter. It was formed in the said base.

  In the bumper assembly structure according to the second aspect of the present invention, when the bumper member is brought close to the support body, the contact portion enters between the base portion and the facing portion. By the way, for example, when the bumper member is attached to the support body or the bumper member is removed from the support body, when the engaging portion or the like formed on the facing portion interferes with the contacting portion, the contacting portion Tries to deform away from the opposing part. Here, a retraction hole penetrating in the opposite direction is formed in the base portion, and the contact portion can enter the retraction hole. For this reason, when the engaging part etc. which were formed in the opposing part and the opposing part interfered with the contact part, it can bend so that a contact part may enter into a retracting hole. Thereby, the big damage | wound etc. of the contact part by interference of the opposing part and the engaging part etc. which were formed in the opposing part can be prevented.

  According to a third aspect of the present invention, in the bumper assembly structure according to the second aspect, the part of the contact portion corresponding to the retraction hole can be elastically deformed toward the retraction hole. It is characterized by that.

Here, when the pressing force from the claw piece is received, the contact portion bends and enters the retraction hole. For this reason, the claw piece does not excessively interfere with the surface of the abutting portion on the side of the facing portion. Thereby, the damage of the contact part by interference of a nail | claw piece etc. can be prevented or effectively reduced.

  Moreover, when removing a bumper member from a support body, you have to let a nail | claw piece pull out from an engagement hole. In such a case, if the abutting portion is tilted so that the abutting portion enters the retraction hole, the abutting portion is separated from the facing portion, and thereby the claw piece comes out from the engaging hole. Thereby, a bumper member can be removed from a support body, without the surface by the side of the opposing part of a contact part interfering excessively with a nail | claw piece.

  According to a fourth aspect of the present invention, there is provided a bumper positioning structure manufacturing method according to a second aspect of the present invention, in which a predetermined bumper member that can be assembled to the support body by approaching the support body provided on the vehicle body side along a predetermined assembly direction.

The opening width of the notch 68 is substantially equal to the inner width dimension of the retraction hole 66 along the left-right direction of the vehicle 10, and the notch 68 is connected to the retraction hole 66. A vertical wall portion 70 that is continuous with the base portion 52 is formed from the bottom of the notch 68. The vertical wall portion 70 extends upward from the bottom of the cutout portion 68 in the vertical direction of the vehicle 10, and the upper end portion thereof is located above the mounting piece 62.

  An upper wall portion 72 as a facing portion is bent from the upper end portion of the vertical wall portion 70 toward the rear in the front-rear direction of the vehicle 10. The distance between the upper wall portion 72 and the mounting piece 62 along the vertical direction of the vehicle 10 is set to be equal to or greater than the thickness dimension of the contact piece 20 at the side end portion 28, and as shown in FIG. The front end side of the side end portion 28 (the front side of the side end portion 28 along the front-rear direction of the vehicle 10) can enter between the upper wall portion 72 and the mounting piece 62.

  A hole 80 is formed in the upper wall 72. A claw piece 82 extends from a portion of the inner peripheral portion of the hole 80 located on the side opposite to the vertical wall portion 70 toward the retreat hole 66. As shown in FIG. 7, the claw piece 82 is formed corresponding to the through hole 36, and when the contact piece 20 enters the predetermined position between the upper wall portion 72 and the mounting piece 62, the claw piece The displacement of the contact piece 20 in the direction opposite to the moving direction of the contact piece 20 when the contact piece 20 enters the through hole 36 and the contact piece 20 is inserted between the upper wall portion 72 and the mounting piece 62.

Therefore, in a state where the side end portion 28 is placed on the placement piece 62, one side end portion 28 can abut against one regulating piece 78, and in this contact state, the other side end portion 28 is in contact with the other side end portion 28. It comes into contact with the regulating piece 78.

<Operation and effect of the present embodiment>
In the present embodiment, when the rear bumper cover 18 is assembled to the back panel 14, first, the rear bumper cover 18 is temporarily placed on the back panel 14. In this temporary placement, the rear bumper cover 18 is approached from the rear side of the back panel 14 along the longitudinal direction of the vehicle 10 (the state shown in FIGS. 4 and 5). In this manner, when the rear bumper cover 18 is displaced from the predetermined assembly position of the rear bumper cover 18 with respect to the back panel 14 along the left-right direction of the vehicle 10 when the rear bumper cover 18 approaches the back panel 14, The distal end side of the side end portion 28 (the side opposite to the base portion 22 of the side end portion 28) contacts the guide piece 64.

  When the leading end side of the side end portion 28 contacts the guide piece 64, the position of the rear bumper cover 18 is shifted in the direction opposite to the contact direction of the side end portion 28 with respect to the guide piece 64 along the width direction of the vehicle 10. . Thus, the rear bumper along the left-right direction of the vehicle 10 in a state where the center position of the mounting piece 62 along the left-right direction of the vehicle 10 and the center position of the contact piece 20 along the same direction substantially coincide with each other. By appropriately correcting the position of the cover 18, the contact piece 20 along the left-right direction of the vehicle 10 and thus the rear bumper cover 18 are positioned.

  Further, when the thin-walled portion 26 enters between the upper wall portion 72 and the mounting piece 62 in this way, the front end portion 30 of the tongue piece portion 34 and the upper surface of the tongue piece portion 34 are clawed as shown in FIG. The piece 82 contacts. Here, the thin part 26 including the tongue piece part 34 can be easily deformed by being thinner than other parts. For this reason, when the tongue piece part 34 with which the claw piece 82 abuts is subjected to a pressing reaction force from the claw piece 82 when the thin portion 26 is inserted between the upper wall part 72 and the mounting piece 62, the claw piece The tongue piece 34 bends on the opposite side to 82.

  Further, here, a retraction hole 66 is formed in the mounting piece 62 corresponding to the upper wall portion 72. For this reason, when the tongue piece 34 is bent as described above, the bent tongue piece 34 enters the retraction hole 66. That is, since the retracting hole 66 is formed in the mounting piece 62, the tongue piece portion 34 can be bent without receiving interference from the mounting piece 62. Thus, since the tongue piece portion 34 can be easily bent, the tongue piece portion 34, and by extension, the contact piece 20 is damaged by the claw piece 82, and further, the contact piece 20 is shaved. Can be prevented or suppressed extremely effectively.

  As described above, as shown in FIG. 8, the abutment piece 20 along the left-right direction of the vehicle 10, and thus the rear bumper cover 18 is positioned, and the front end 30 of the thin portion 28 abuts the vertical wall portion 70. When the rear bumper cover 18 is moved to the position shown in FIG. 7, the claw piece 82 and the through hole 36 face each other so that the claw piece 82 enters the through hole 36 and interference from the claw piece 82 is eliminated. The tongue piece 34 is restored to its original shape by its own elasticity. Thus, the temporary placement of the rear bumper cover 18 with respect to the back panel 14 is completed, and thereafter, a predetermined portion of the rear bumper cover 18 is fastened and fixed to a predetermined portion of the back panel 14 by fastening means such as bolts. Is attached to the back panel 14.

  Thus, in the present embodiment, the rear bumper cover 18 is moved closer to the back panel 14 while abutting the side end portion 28 of the contact piece 20 against the restriction piece 78, so that the contact along the left-right direction of the vehicle 10 is achieved. The contact piece 20 can be easily positioned.

  Moreover, the restriction piece 78 is formed by being cut and raised from the placement piece 62. Therefore, since the regulating piece 78 can be formed from a single metal flat plate during the press molding process such as punching or bending, the bumper bracket 50 having the regulating piece 78 can be formed at a low cost.

  On the other hand, when removing the rear bumper cover 18 from the back panel 14 for maintenance of the vehicle 10 or the like, bolts or the like for fixing the rear bumper cover 18 to the back panel 14 are removed, and the rear bumper cover 18 is lifted upward. As shown in FIG. 9, when the rear bumper cover 18 is lifted, the thin portion 28 on the mounting piece 62 bends around the vicinity of the through hole 36. However, since the retracting hole 66 is formed below the tongue piece 34, the tongue piece 34 enters the retracting hole 66 without being bent even when the rear bumper cover 18 is lifted.

  As the tongue piece 34 rotates downward so as to enter the retraction hole 66, the claw piece 82 comes out of the through hole 36. Therefore, in this state, the rear bumper cover 18 can be easily pulled out and removed without receiving excessive interference from the claw piece 82. Moreover, since there is no excessive interference from the claw piece 82, when the rear bumper cover 18 is pulled out, the tongue piece portion 34 and the contact piece 20 are damaged by the claw piece 82, and further, the contact piece It can prevent or suppress very effectively that 20 is shaved.
