Abstract:
Provided is a lightweight foam molded body (1) which can be manufactured at low cost, and allows an effective long-term reduction in the noise generated between a vehicle structure and the foam molding body. Also provided is a molding die (10) whereby it is possible to mold a great-looking foam molded body having a beautiful appearance. The foam molding body (1) has contact surfaces (5) making contact with a vehicle structure (4) and non-contact surfaces (6) making no contact with the vehicle structure (4). The contact surfaces (5) are rough surfaces, and the non-contact surfaces (6) are smooth surfaces which are smoother than the contact surfaces (5). The molding die (10) is designed to manufacture the foam molded body (1) by foam molding a synthetic resin within a cavity (13). Recessed portions (15), which are part of the formation surface forming the cavity (13), are each formed to be a rough surface, and the rest of the formation surface is formed to be a smooth surface which is smoother than the rough surface.
