PURPOSE:To reduce the cost of a metal mold by using the same fitting body regardless of the presence or absence of fitting parts by making the thickness of the fitting parts for the fitting body smaller in fitting the fitting parts to the fitting body. CONSTITUTION:A part fitting device has a fitting body 4 as a thermosetting or thermoplastic resin molding and a fitting part 6 to be attached to the fitting body 4. The thicknss of the fitting portion 5 of the fitting part 6 is made smaller. The same fitting body 4 can thus be used regardless of the presence or absence of fitting parts to the fitting body 4, and thereby the cost of metal molds can be improved by reduction.
