To attach the side molding M ₁ made of the side surface of the synthetic resin, the synthetic resin clip is used. In order to attach the side molding to the side surface of the automobile body, a plurality of clips are integrally attached to the set positions of the side molding in a manufacturing process of the side molding, and the side molding in this state is transported to an automobile assembly line. doing. Therefore, if the position of the clip shifts during the mounting of the clip or during the transportation of the side molding, the clip cannot be mounted on the vehicle body as it is, so that the position of the clip must be corrected, which requires extra man-hours and time. there were.

The above-mentioned clips have various structures, one of which is shown in FIG. 10 and FIG. The clip C ₁ ′ is a push-in type, and includes a clip main body 1 having a square planar shape and a locking body 2 provided integrally therewith. Clip body 1
The first step portion 3 is provided on one of two opposing sides of a surface on which the locking body 2 is provided (hereinafter, referred to as a “locking body forming surface”), and the other side is provided with a first step portion 3. A horizontal projection 4 is provided integrally at the center. A pair of locking arms 5 are provided on both sides of the horizontal projection 4 in the clip body 1.
Is provided. The pair of locking arms 5 stand up from the surface opposite to the locking body forming surface of the clip main body 1, and are elastically attached to the clip main body 1 with their distal ends facing the locking body forming surface of the clip main body 1. It is integrally formed so as to be deformable. The distal ends of the pair of locking arms 5 are free ends, and a second step 6 is formed at the free ends. On the other hand, side molding M ₁ has a pair of flanges 8 on the back side of the curved portion 7 is formed integrally in the longitudinal direction, have a substantially C-shaped cross section, between a pair of flanges 8 An opening 9 is formed. The inner periphery of the side molding M _1, the core metal 11 is provided for reinforcing the ends of the core metal 11 provided on the inner side of each flange portion 8 is covered with a resin which forms a side molding M ₁ Have been done. Therefore, the inner end surface 8a of the flange portion 8 is formed of resin. The clip C ₁ ′ is integrally attached to the set position of the side molding M ₁
To this end, the adhesive S was applied to the inner surface of the core metal 11 at the mounting position, and in this state, the clip C ₁ ′ was pushed in from the opening 9 of the side molding M ₁ . Thus, while the locking arm 5 is elastically deformed, the clip body 1 is fitted into the space portion 12 of the side molding M _1, first and second
Each of the stepped portions 3, 6 is formed on the inner end face 8 of each of the flange portions 8.
The clip C ₁ ′ is integrally attached to the side molding M ₁ by press-fitting engagement with the portion a. When the clip body 1 is fitted into the space portion 12 of the side molding M _1, the surface opposite the locking member formation surface of the clip body 1 is bonded to the core metal 11 via an adhesive S, the horizontal projection 4 , Flange 8
Abuts on the inner end surface 8a of the first member. As described above, the clip C ₁ is formed by elastically deforming the locking arm 5 and elastically engaging the second step 6 provided at the tip thereof with the inner end face 8 a of the flange 8. Although the fixing strength of 'is increased, the clip main body 1 is bonded and fixed to the core metal 11 using an adhesive because sufficient fixing strength cannot be obtained by this method.

FIGS. 12 and 13 show another clip C ₂ ′.
The clip C ₂ ′ is of a type that is rotated and attached integrally to the side molding M ₂ . This clip C ₂ ′ is a curved portion 21 of the side molding M _2.
And a locking body 23 provided integrally with the clip body 22. The surface of the clip body 22 on which the locking body 23 is provided is flat, and a pair of rotation restricting projections 24 are provided on this surface symmetrically with respect to the center of rotation of the clip body 22. I have. Configuration of side molding M ₂ is a substantially identical to the side molding M _1, provided in the longitudinal direction a pair of flange portions 25 on the back side of the curved portion 21, between the pair of flange portions 25 Opening 26
Are formed. The clip body 22 is rotated so as to be fitted into the space portion 28 of the side molding M _2, each corner which faces along the diagonal in the clip body 22 is notched in an arc shape. The clip C _{2 'to} attach integrally to the side molding M _2, leave applying an adhesive S to the inner surface of the core metal 27 of the clip mounting portion, the clip C ₂ in this _state' and 12 two placed at the position indicated by dash-dotted space 2 of the side molding M ₂
The clip C ₂ ′ is rotated in a predetermined direction. As a result, the pair of rotation restricting projections 24 abut against the respective inner end surfaces 25a of the pair of flange portions 25 and cannot rotate, thereby positioning the clip C ₂ ′ in the rotational direction. Clip C to the side moldings _{M 2
2} 'is fixed by the adhesive S applied to the metal core 27, and the rotation restricting projection 24 has only a function of determining the rotation position of the clip when the clip is attached, and does not contribute to fixing the clip at all. . Therefore, an adhesive is indispensable for fixing the clip.

As described above, in the past, an adhesive was used to integrally attach the clip to the side molding and prevent its displacement. As described above, when the adhesive is used, the clip may be displaced until the adhesive is completely dried (it takes about two to three minutes). Further, the adhesive scattered during the bonding operation may adhere to the surface (decorative surface) of the side molding, and may cause the side molding to be defective. Further, there is also a problem that the adhesive strength varies due to the non-uniform application amount of the adhesive, and the clip is displaced. In order to solve the above-mentioned problem caused by the use of the adhesive, if the clip body is forcibly fitted into the space of the side molding in a tightly fitted state (a state in which no gap is formed between the two), Therefore, there is no displacement of the fixing position of the clip with respect to the side molding. However, when the clip body is closely fitted in the space of the side molding, the core metal made of aluminum is deformed and swells, and the deformed portion is recognized from the outside, and the appearance of the side molding is significantly impaired. Another problem arises.
