Abstract: Mainly, local wall thinning is prevented. The invention relates to a vacuum forming method for fabricating a resin-molded article. The vacuum forming method includes pressing a thermoplastic resin sheet 201 softened by heating into a vacuum forming mold 202 using a core mold 203 to stretch and deform thermoplastic resin sheet 201 at the same time, and bringing the thermoplastic resin sheet 201 into intimate contact with the vacuum forming mold 202 by vacuum suction to shape the thermoplastic resin sheet 201. In the process of closing the vacuum forming mold 202 and the core mold 203, at least part of the thermoplastic resin sheet 201 is preshaped using air pressure in such a way that the at least part of the thermoplastic resin sheet 201 is locally stretched and deformed at the same time and thus brought into intimate contact with the core mold 203.

Abstract: A soft insert component having a rigid body portion in the vicinity of a marginal part of one surface side is insert molded in integration to a foamed molding. The foamed molding with the soft insert component includes a triple layered structure having a skin material, a core material, and a foamed layer. The skin material includes an insert component fixing portion onto which the soft insert component can be fixed. The core material includes a rigid body-supporting portion able to support the rigid body portion while resisting against a compression force applied to the soft insert component during foam molding, and the foamed layer is formed between the core material and a skin layer formed of the skin material and the soft insert component.
