要になる等の問題があつた。-Prior Art- As is well known, a bumper skin A made of a hard resin such as polypropylene is used by being attached to a rigid armature B with a box-shaped cross section extending in the vehicle width direction. Conventionally, the upper part of the armature B is fixed to the armature B in a structure as shown in FIGS. 5 and 6. That is, as shown in FIG. 5, the mounting wall a1 formed at the lower part of the bumper skin A is connected to the lower side b1 of the highly rigid metal armature B by the retainer C and the mounting bolt D.
is fixed to the upper flange b of armature B.
2 is bent substantially horizontally toward the vehicle body so as to be parallel to the upper wall a2 of the bumper skin A. and,
The upper wall end a3 and the upper flange b2 are firmly fixed at multiple positions in the vehicle width direction by mounting bolts E passing through them and armatures B laminated on the upper wall end a3 (for example, in actual use). Kaisho 53-26044
(see publication). However, in the same conventional structure, when assembling the bumper, the retainer C is placed on the surface of the upper wall end a3 where there is no reference for positioning, and the bolt holes of the retainer C are aligned with the mounting holes of the upper wall end a3. It is necessary to pass the mounting bolt E,
The assembly work was difficult. In addition, in the structure described above, the upper wall end a3 between the mounting bolts E is
is only held by the frictional force of retainer C, so if there is a temperature change, armature B
Due to the difference between the coefficient of thermal expansion of
The front surface a4 of the bumper skin A is wavy, detracting from the product value of the bumper. In the above structure, a sight shield F is attached to the vehicle body to hide the retainer C, but in the conventional structure, the sight shield F is attached to the vehicle body to hide the retainer C.
is located on the upper wall end a3, so the sight shield F becomes large and there is less freedom in designing the exterior of the vehicle.In the event of a light collision, the upper wall end a3 has a uniform thickness, There were problems such as an external force acting directly on the retainer C due to the deformation of the wall, making it necessary to replace the deformed retainer C.

As shown in the first figure, partial vertical walls 5 bent downward, that is, toward the armature, are formed on b, and these vertical walls 5 are connected to vertical flanges 4a that stand up vertically from the upper surface of the armature 4. Fixed. That is, these vertical walls 5 are arranged in the vehicle width direction at intervals with elongated holes 5a formed in the vehicle width direction on their surfaces, and these vertical walls 5 and the upper wall end portion 1b A protrusion 6 extending across the entire bumper skin 1 in the vehicle width direction is integrally formed at the connection portion with the bumper skin 1 . This protrusion 6 protrudes above the upper surface of the bumper skin 1 while being positioned directly above the vertical wall 5, and is retained by a retainer 7 as will be described later.

The vertical portion 7a forming the bolt hole 8 is connected to the vertical wall 5.
and then attach the armature 4 with the mounting bolt 9.
is fixed to the vertical flange 4a of. Moreover, it is integrally molded on the upper part of the vertical part 7a. The "U"-shaped bent portion 7b is hooked onto the protrusion 6 of the bumper skin 1 in order to prevent the aforementioned protrusion 6 from moving in the longitudinal direction of the vehicle body.

バンパ表皮１を成形できる。 Since the bumper according to the embodiment has the above-described structure, the bumper skin 1 can be molded using a mold as shown in the fourth figure. That is, FIG. 4 is a horizontal sectional view taken along a plane including the cavity k1 that molds the vertical wall 5 mentioned above, and the cavity k2 that molds the entire bumper skin 1 is formed by the male mold X and the female mold inside the bumper skin 1. Formed by Y. Also,
On the surface of the male mold It is supported so that it can move along the Z direction. Therefore, the bumper skin 1 was formed using the same molding die.
For injection molding, after the resin has solidified, while holding the bumper skin 1 in the female mold Y, push the core x in the directions of arrows J 1 and J 2 , and each Since the core x moves along the mounting groove Z, when the core x reaches the intermediate spacing position after the vertical wall 5, the core x is removed from the bumper skin 1 and the male mold X is removed from the bumper skin. 1, the bumper skin 1 having a plurality of partial vertical walls 5 can be molded using the same mold.

高くなる。 Furthermore, in order to assemble the bumper of the above embodiment, when the bent portion 7b of the retainer 7 is hooked onto the protrusion 6,
Since the positional relationship of the retainer 7 with respect to the bumper skin 1 is specified, the upper part of the bumper skin 1 can be assembled with the mounting bolts 9 by only slightly adjusting the retainer 7 with respect to the bumper skin 1. The bent portion 7 of the retainer 7 in the assembled state
b has a good appearance and does not require the sight shield 10, but even if a sight shield 10 is provided, a small sight shield 10 as shown in the imaginary line will suffice, so there is less freedom in terms of appearance design. It gets expensive.

等の利点がある。 Furthermore, when the bumper is in an assembled state, the bent portion 7b of the retainer 7 prevents the protrusion 6 from moving in the longitudinal direction of the vehicle body, so the upper wall end 1b may move in the longitudinal direction of the vehicle body due to temperature changes. Bumper skin 1
This can prevent the entire surface from becoming wavy. On the other hand, if the bumper skin 1 is involved in a light collision,
Since the bumper skin 1 breaks as shown by the imaginary line from the part near the protrusion 6 where the cross-sectional change is large, the retainer 7
Since no excessive force is applied to the retainer 7 and the retainer 7 is not deformed, there is an advantage that there is no need to replace the retainer 7.

等の効果がある。-Effects of the invention- As is clear from the above explanation, in the present invention, since the bent portion of the retainer is locked to the protrusion, movement of the protrusion in the longitudinal direction of the vehicle body is prevented, and temperature changes This can prevent the protrusions from moving in the longitudinal direction of the vehicle body and causing the front surface of the bumper skin to become wavy. In addition, in the case of the bumper of the present invention, in the case of a light collision, the bumper skin will break from the part closer to the protrusion where the cross-sectional change is large, so no excessive force will be applied to the retainer, and deformation of the retainer can be prevented.
This has the advantage that unnecessary replacement of the retainer is not required.
