（特開昭55−31610号）。 Conventionally, this molding M (see Figures 2 and 3) has one longitudinal edge m ₁ bent into a hook shape.
It is attached by locking it with a U-shaped receiving groove S provided at the base of the flange part F, and by locking the other edge m ₂ bent into an approximately inverted L shape with a latching plate 1. (Utility Model Publication No. 57-130743). The latching plate 1 is attached to a rib R protruding inside the bumper body.
In addition to fitting and fixing the letter-shaped bracket 2, it is threaded and supported on the axis of a screw 3 screwed into the rising part of the bracket 2, and by adjusting the screw 3, the L-shaped edge _m2 of the molding M is pulled. Fixedly attached. However, with this molding mounting structure, there is a risk that the screw 3 may loosen due to vibration during driving, causing rattling, or that the screw 3 may loosen and the molding M may come off, and the assembly work is also complicated. In addition, there is a drawback that the number of parts is large, leading to high costs. In addition, in the bumper B, sink marks may occur partially due to heat shrinkage after resin molding, and the mounting surface of the molding M may be deformed to form a dent. If the receiving groove S side is installed in continuous contact with the flange part F over the entire length in the longitudinal direction, as in the mounting structure of M, the molding M will bend at the concave part due to the tension applied from the latching plate 1 side, so that it will not straighten. Situations where it is not possible to install the product while maintaining its properties are likely to occur. In contrast, in the past, an engagement groove was provided along the longitudinal direction in the shoulder of the resin bumper, and a downwardly protruding lip was provided on the end side of the center part of the upper wall located on the other side, and these engagement grooves were provided on the other side. A bumper molding with a substantially C-shaped cross section is attached to the upper surface side of the resin bumper by hooking it to the groove and lip and engaging the metal bumper molding elastically, and a resin bumper molding that hooks one side of the bumper molding is attached to the upper surface side of the resin bumper. It is also known to protrudely mold a clip on the shoulder and elastically engage the bumper molding with this clip (Japanese Patent Laid-Open No. 55-31610).

で変形が生じ易い。 This molding attachment structure is preferable to the above-mentioned structure in which the retaining plate is attached with screws because the lip or clip for retaining the bumper molding is integrally molded on the body of the bumper. However, in this bumper molding mounting structure, the end of the bumper and at least one side of the bumper molding are in continuous contact along the entire length in the longitudinal direction, so as mentioned above, the bumper molding is deformed by heat shrinkage after resin molding. If this occurs, the molding will be installed in accordance with the deformation of the bumper, resulting in a situation where the molding cannot be installed while maintaining straightness. Further, even when the bumper molding is hung with a clip, deformation is likely to occur at the clip latching position because the other end is in direct and continuous contact with the bumper.

A plurality of protrusions are provided at regular intervals in the longitudinal direction by protruding inward from one edge of the main body, which is formed into a substantially hook shape, and the protrusions are brought into contact with the inner surface of a receiving groove provided at the base of the flange portion. One edge piece of the dewing main body is fitted into the receiving groove and locked, and the U-shaped holding part is fitted and fixed to the rib protruding from the main body of the resin bumper via the base of the flange part, and the flange part A plurality of spring clips each having a locking portion extending upward along the back surface of the molding body are attached at positions corresponding to respective projections protruding from one edge of the molding body, and the locking portion of each spring clip is attached to a position corresponding to each protrusion protruding from one edge of the molding body. It is constructed by fitting the molding body into the inside of the other edge formed in the shape of a hook, and pulling and fixing the molding body to the vehicle body side.

で抜き外れないよう嵌着できる。 When attaching the bumper molding M, a spring clip C made of a highly elastic metal plate such as a spring steel plate is used (see FIG. 5).
The spring clip C includes a substantially U-shaped clamping part 20 which is fitted and fixed to a rib R protruding from the main body of the bumper B via the base of the flange part F, and a clamping part 20.
It is formed from an intermediate portion 21 extending upward from 0 and a locking portion 22 whose tip is folded back. Middle part 21
It is preferable that the spring clip C is bent and formed so as to extend along the flange portion F of the bumper B so as to match the shape of the back surface of the flange portion F. This allows the spring clip C to be stably attached. Further, it is preferable to cut and form a plurality of inverted claws 23 on the clamping portion 20, so that when fitted to the ribs R of the bumper B, the inverted claws 23 can be fitted so as not to bite into the ribs R and come off.

を全く生ずることなく取付けることができる。 When using this spring clip C, the main body of the molding M is placed on the flange part F of the bumper B, and after one edge 10 of the molding M is engaged with the receiving groove S provided at the base of the flange part F, the upper end side The molding can be attached and supported by hooking the other edge 12 of the molding main body M located at. The spring clip C is fitted and fixed in advance to the rib R of the bumper B with the U-shaped holding part 20 in a position corresponding to the protrusions 11, 11... provided on one edge 10 of the molding main body M. A plurality of them are installed at desired intervals in the longitudinal direction. When the molding M has one edge 10 engaged with the receiving groove S, the tip side of the spring clip C is located outward, so
The other edge 12 cannot be immediately engaged with the upper edge of the spring clip C (see FIG. 6a). When the other edge 12 comes into contact with the upper edge of the spring clip C and then presses it, the guide edge 13 shifts the locking part 22 of the spring clip C slightly backward and receives it inside, and then the locking part 22 springs back to its original state. It can be engaged with the spring clip C (see Figure 6b). In this meshed state, the spring clip C tensions the other edge 12 of the molding M, so that the molding M can be securely covered and fixed to the flange portion F. In addition, on one edge 10 of the molding M, the protrusions 11, 11... fit into the receiving groove S and partially contact the inner surface of the groove, and the other end is also provided with spring clips C, C... attached at corresponding positions. Since it is partially latched, even if bumper B is deformed due to partial sink marks, etc., it can be installed with straightness without being affected, and it can be installed without causing any looseness to molding M. be able to.

The molding that comes in contact with the bumper is partially latched onto the flange of the bumper using spring clips installed at corresponding positions, so even if the bumper is deformed due to local sink marks, it will not be affected and will remain straight. It can be installed while maintaining its properties, and it can be installed securely without rattling or coming off.
