It is comprised of a resin bumper skin 3 with a substantially U-shaped cross section that is attached to cover the iJ-, and depending on the type of bumper, a shock absorber is disposed between the two. In this type, a mounting 7 flange 4 is provided upright along the upper edge of the Bambalein 7 os 1, and bolt mounting holes 5 are bored at predetermined intervals in this mounting 7 flange 4. A weld nut 6 is welded to the front part of the bolt mounting hole 5, and a plurality of locking holes 9 are drilled in the bottom wall 1 of the bumper rein 7 os 1. A mounting wall 11 extending in the vehicle width direction is integrally provided on the back side of the upper wall 10 of 3. Nine bolt insertion holes 12 are formed in this mounting wall 11 at positions corresponding to the bolt mounting holes 5. In addition, the lower wall 1 of the bumper skin 3
3 has an insertion hole 14 for the clip 8 corresponding to the locking hole 9.

が面倒であると共に、作業性の悪いものとなっていた。However, during demolding, the upper edge of the inner mold 1B gets caught on the mounting wall 11, making it difficult to pull it out backwards. Therefore, it was not possible to simplify mold barrel construction, and the resin materials that could be used were also limited. Furthermore, when installing the bumper skin 3'ft, as shown in FIG. Since the wall 13 has to be bent while assembling the bumper, it is troublesome and the workability is poor.

なる。In the first embodiment shown in FIGS. 6 and 7, the resin bumper skin 3 made of polypropylene or the like has a bumper skin main body 19 approximately U-shaped in cross section, as in the past. A mounting wall 11 is formed along the vehicle width direction on the back surface of the rear side of the @10 as a mounting part for fixing it to the Pamperrain 7aus 1. In this embodiment, the base of the mounting structure 11 is It is formed into a thin wall by grooves provided on the surface side, and the thin wall portion is configured as a thin hinge 20. Therefore, the mounting wall 11 rotates about the thin hinge 20' with respect to the bumper skin main body 19,
As shown in FIG. 6, when it is rotated rearward, it can be bent until it substantially touches the bumper skin main body 19.
尚、バンパ表皮本体１９の下壁１３には、従来と同様、
クリップ８の挿通孔１４が穿設されている。Incidentally, the lower wall 13 of the bumper skin body 19 has the following parts as before.
An insertion hole 14 for the clip 8 is bored.

り固定する。The thin hinge 20 is integrally provided by protruding a part of the mounting wall Venus that forms this part when molding the Bamba skin 3, and after resin injection, the Pamba skin main body 1
When pulling out the inner mold forming the inner surface of 9, it can be easily removed by bending the mounting wall 11 backward from the thin hinge 20. In addition, when attaching the Pamba skin 3 to the Bamba reinforcement 1,
As shown in FIG. 6, by rotating the mounting wall 111 rearward to make it approximately horizontal, the bumper skin 3 can be easily attached to a predetermined position from the front side of the bumper reinforcement 1, and then, After the mounting wall 11 is returned to the vertical direction, it is brought into close contact with the mounting 7 flange 4 and fixed with bolts 15 as shown in FIG. Note that the lower wall 13 of the bumper skin 3 and the bottom 417 of the bumper reinforcement 1 are fixed with clips 8.
第８図は本発明の第二実施例を示したものであり、バン

のである。FIG. 8 shows a second embodiment of the present invention, in which the far end of the upper wall 10 of a bumper skin main body 19 is formed as a mounting wall 11. That is, in this example, pampa epidermis 3
At the time of molding, grooves are formed on the upper surface side along the vicinity of the rear wall of the earthen wall 10, and the thin wall portion is configured as a thin hinge 20.
従って、この実施例では、成形時には取付壁１１が上壁
１０の一部として水平状に形成されるので、金型を抜く

It becomes possible to further simplify the structure. In addition, when attaching the bumper skin 3 to the bumper reinforcement 1, cover it from the front side of the bumper reinforcement 1 in the state at the time of molding, and attach the mounting wall 11 to the thin hinge 2 at a predetermined position.
The bumper reinforcement 1 can be bent inward around 0 and brought into close contact with the mounting flange 4 of the bumper reinforcement 1, and both can be fixed with bolts 15.
以上説明したように、本発明に係る樹脂バンパ構造によ

を奏する。As explained above, according to the resin bumper structure according to the present invention, demolding work after molding the bumper skin becomes easy.
In addition to improving work efficiency, it is possible to simplify the mold structure, and it is also possible to use resin materials that could not be used conventionally due to the difficulty of demolding. Furthermore, it is possible to improve workability when standing up the resin bumper.
