【Example】

 In the illustrated embodiment, 10 is a rectangular substrate and 20 is a stud, and the substrate and the stud are integrally formed of an appropriate plastic, for example, polyacetal resin. A front end portion 10 'of the substrate 10 is a vertically thickened repellent (bulb) -shaped cross-section receiving portion 11 whose end face is a convex curved surface 11'. When fixed to the vehicle body panel of an automobile and the lower surface of the front window glass or the rear window glass is received by the end surface of the convex curved surface, the size of the substrate 10 is about 26 mm in the long side between the front end 10 'and the rear end 10 ". The width or short piece is about 22 mm, and the four corners are rounded (R) with no corners, and the top surface is recessed with an indicator 12 such as an arrow indicating the direction of the receiving portion 11. It is set up.

The stud 20 has a rigid leg 21 extending substantially vertically and downward from the rear portion of the lower surface of the substrate, and a fold-up extending obliquely upward from the lower end of the rigid leg 21 toward the front end 10 ′ of the substrate. The elastic arm 22 is provided with an engaging portion 23 which is thickened at its tip and has an inclined surface which is obliquely upward with respect to the lower surface of the substrate. The distance between the lower surface of the substrate and the upward slope 23 'of the engaging portion 23 corresponds to the thickness of the panel. The rigid leg piece 21 is composed of an upper half portion 21a that is wide and thick in the direction of the short piece of the substrate, and a lower half portion 21b that has the same thickness and narrows downward, and from the lower end of the lower half portion 21b. The lower half portion 22a of the elastic arm 22 extending obliquely upward is widened upward similarly to the lower half portion 21b, and the upper half portion 22b has the same width as the upper half portion 21a of the rigid leg piece. Since the elastic arm 22 has the narrowest lower end and is connected to the lower end of the rigid leg in a folded manner, the upper part of the connecting part 24 may slightly bend toward the rigid leg. You can The slanting surface 23 'of the engaging portion 23 is provided with engaging grooves 25a, 25b vertically, in this embodiment, in two stages. Further, the rigid leg piece 21 has a sawtooth-shaped check claw 26 on the rear surface facing the rear end 10 "of the board. The distance between the lower surface of the board and the flat upper surface 26 'of the check claw 26 is also a panel. Corresponding to the thickness of.

To fix the substrate 10 to the vehicle body panel P of an automobile and to position and receive the lower edge of the window glass G by the convex curved surface 11 ′ of the receiving portion 11 at the front end 10 ′ of the substrate 10, A square hole that is slightly wider than the rigid leg and the upper half 21a, 22b of the elastic arm, and the length between the front and rear edges allows the elastic arm 22 to bend slightly toward the rigid leg 21 and pass through. Open H. Then, a non-woven strip 13 is attached to the convex curved surface 11 'at the front end of the substrate by adhering it so that the convex curved surface 11' contacts the lower edge of the glass G through the non-woven strip 13. .. It is preferable that protrusions 14 and 14 are provided at both ends of the convex curved surface 11 ′ in a square shape, and the non-woven fabric strip 13 is positioned and attached between the protrusions 14 and 14. Further, in order to prevent water from entering the inside through the hole H of the panel, a packing 14 having an outer shape slightly larger than that of the hole H is fitted to the base of the rigid leg piece 21 so as to be along the lower surface of the board. Put.

When the rigid leg 21 and the elastic arm 22 are pushed into the hole perpendicular to the panel P with the rear surface of the rigid leg 21 along the rear edge h ″ of the hole H, the elastic arm of the hole H moves. When pushed by the front edge h ', it gradually bends largely toward the rigid leg piece 21. When the lower surface of the substrate 10 abuts on the upper surface of the panel, the check claw 26 on the rear surface of the rigid leg piece has a hole. The trailing edge h ″ of H passes downward, and the elastic arm 22 passes through the leading edge h ′ of the hole downward and returns slightly to restore the original state. 23 'comes into contact with the front edge of the hole from below, and when the thickness of the panel P is, for example, 1.8 mm, the lower engaging groove 25b on the inclined surface 23' engages with the front edge of the hole from below. When the thickness of the panel is, for example, 2.2 mm, the upper engaging groove 25a engages with the front edge of the hole from below, and the elastic arm 22 remains. A restoring force is applied to the front edge of the hole H to fix the substrate 10 on the panel. Thus when the tanning positioning by receiving the window convex surface 11 of the front end of the substrate 10 a lower edge of the glass G ', back edge h "after the holes for the external force F ₁ based on the weight of the window glass G up stiffness of the rigid legs 21, and strongly opposed by the engaging force between the front edge h 'of the upper engaging portion 23 and the hole of the resilient arms 22. Further, the external force F ₁ and the right angle substrate 10 The external force F ₂ applied to the front end is strongly opposed by the engaging force of the check claw 26 and the trailing edge h ″ of the hole. Further, with respect to the force for pulling out the rigid leg pieces, they are opposed by the engaging force between the engaging portion 23 and the front edge h ′ of the hole and the engaging force between the check claw 26 and the rear edge h ″ of the hole. Therefore, once the substrate 10 is fixed on the panel as described above, the substrate immovably positions the work at its front end.

The rigid leg piece 21 is formed to have a thickness, but if this is done, a complex cooling time will occur between the rigid leg piece 21 and the other thin parts, and it will be deformed by the strain generated inside and will not be the intended product. Disappear. For this reason, the rigid leg pieces 21 are provided with slits 27 reaching from the both sides to the vicinity of the center of the rigid leg pieces 21 so as to have an H-shaped cross section with a uniform thickness to prevent deformation during molding. Further, the lower half portion 21b of the rigid leg is tilted slightly forward with respect to the upper half portion 21 which is perpendicular to the lower surface of the substrate. This is to improve the insertability into the hole H of the panel. is there.
