CONSTITUTION: Foaming plastic stock 38 is poured between an upper mold 32, which has a surface corresponding to the rear surface of a seat part member 18, and a lower mold 36, in which a molding groove 34 corresponding to the seat part 18 is provided, so as to produce the eat part member 18 by being released from the upper mold 32 and the lower mold 36 after the expansion of the foaming plastic stock 38. In this case, as an anchoring means, a hook 40 is installed on the rear surface, for example, of tire upper mold 32 so as to anchor a cloth 16 to the hook 40. When the foaming plastic stock 38 is expanded, the cloth 16 adheres to the foamed plastic. After being released from the upper and the lower molds 32 and 36, the foamed plastic, to which the cloth is bonded, is trimmed along its outer peripheral edge so as to obtain the seat part member 18.
