求される等の問題点があつた。(Prior art) As an automobile interior material in which metal brackets are fixed to a thermoplastic synthetic resin substrate, mounting holes are formed in the mounting legs of the brackets in bosses protruding from the synthetic resin substrate. It is already known that a bracket is fixed to a synthetic resin substrate by having a retaining head in which the tip of the boss is fitted and melted and crushed. (For example, Utsukai 57-
(Publication No. 78912) (Problem to be solved by the invention) However, since such automobile interior materials experience severe running vibrations, the lower surface of the retaining head is brought into close contact with the mounting leg of the metal bracket. Unless the welding horn is pressed strongly until the welding point is reached, rattling will occur. For this reason, when forming the retaining head, the welding horn must be lowered until it comes into contact with the metal brackets, resulting in a harsh contact sound, and it is also difficult to obtain an appropriate fixing state. In order to achieve this, there were problems such as the need for dimensional accuracy in the descending amount of the synthetic resin substrate, metal brackets, or welding horn.

A metal bracket that is fixed to a synthetic resin substrate by fitting a mounting hole provided in the metal bracket into a protruding boss and having a retaining head made by melting and crushing the tip of the boss. In an automobile interior material in which brackets are fixed to a synthetic resin substrate, the edges of the mounting holes of the brackets are made to stand up as tapered short cylindrical portions, and the retaining head has a recessed portion at the center of the top. It is characterized by having an umbrella shape in which a part of the periphery is formed at a hem portion along the upper half of the tapered short cylindrical portion.

供できるものである。(Function) If this type of automotive interior material is installed inside the vehicle body like conventional automotive interior materials of this type, the boss part protruding from the synthetic resin substrate will be melted and crushed to prevent it from coming off. A part of the head is wrapped around the upper half of the tapered short tube that rises above the edge of the mounting hole of the bracket, so that the lower surface of the head for preventing it from coming off is Even though it is not in direct contact with the mounting legs of the brackets, it has sufficient mounting strength and does not wobble due to repeated running vibrations.
The head for preventing slipping out has a recess formed in the center of its top, and the hem part, which is a part of the periphery, is located in the upper half of the tapered short tube part, and the hem end does not reach the mounting leg. When forming the stopper head with the welding horn, an accurate fixation can be obtained without lowering the welding horn until the lower end touches the mounting leg, and there is no contact noise. Since dimensional accuracy is not required for the descending amount of the synthetic resin substrate, metal brackets, or welding horn, an appropriate fixing state can be obtained, so it can be provided at a low cost.

なくて安価に量産できる利点もある。(Effect of the invention) In this structure, the retaining head 10, which is formed by melting and crushing the tip of the boss portion 3 protruding from the synthetic resin substrate 1, has a part of the periphery of the boss portion. It is formed on the hem 10a attached to the upper half of the tapered short cylindrical portion 9 provided at the edge of the mounting hole of the bracket 4 into which the bracket 3 is fitted, so that it does not wobble even after repeated running vibrations. A strong fixing state that does not cause sticking can be obtained, and by forming a recess in the center of the top of the retaining head 10, processing with a welding horn is easy, and the lower surface of the retaining head 10 can be attached to the brackets 4. Since there is no need to press the welding horn until it comes into contact with the mounting leg 7 of the bracket, there is no abnormal noise caused by contact between the welding horn and the brackets 4 during assembly work, which not only improves the working environment but also improves the working environment. There is also the advantage that mass production is possible at low cost since precision is not required in the dimensions of each part of the substrate 1 and brackets 4, the amount of descent of the welding horn, etc.

従つて、本考案は従来のこの種金属製ブラケツ
