成形における反り防止構造。[Claims for Utility Model Registration] (1) A resin material is insert-molded into a plate material with a plurality of through holes, and a boss portion provided in the resin material is inserted into the through holes to insert the resin material into the plate material. In a structure in which a material is attached and supported, the inside dimension in the length direction of the through holes other than one of the through holes opened in the plate material is relative to the diameter dimension of the boss portion of the resin material. A warpage prevention structure in insert molding, which is characterized by a large size. (2) One through hole is formed in a perfect circular shape, the other through holes are formed as long holes along the length direction of the resin material, and the boss portion is formed with a diameter dimension corresponding to the one through hole. A warpage prevention structure in insert molding according to claim 1 of the registered utility model.
