BACKGROUND OF THE INVENTION Several methods have been proposed to obtain molded products containing reinforcing bodies. One of the methods is to use an injection molding machine to install a reinforcing body in a mold in advance and perform injection molding to obtain an integrated molded product. With this method, the reinforcing body may be deformed by the fluid pressure during injection molding, a portion of the reinforcing body may be covered with the injected resin, resulting in poor appearance, or the mold may be cooled to allow the resin to cool and solidify. Since the reinforcing body attached to the mold is also at a low temperature, it has various drawbacks such as poor adhesion between the reinforcing body and the injected resin.

DETAILED DISCLOSURE OF THE INVENTION The reinforcing body of the present invention is effective against externally or internally generated forces such as impact, tension, bending, compression, thermal distortion, etc. The material is not particularly specified, but examples include: metal, wood, paper, cloth, synthetic resin, glass fiber,
Single materials such as carbon fibers, synthetic resin fibers, and metal fibers or combinations of these materials are used. It is desirable that the reinforcing body has a shape that matches a predetermined portion of the final molded product shape so that the reinforcing body can fully exhibit its reinforcing effect.
