  The present invention is applied to interior parts for vehicles such as door trims, luggage side trims, and instrument panels, and armrest parts and other ornaments attached to the interior parts. It is also possible to apply to parts. As the base material, a relatively hard synthetic resin material such as hard polyvinyl chloride, polypropylene, polyethylene, or ABS is preferably used, but it may be made of other materials such as metal. As the surface layer material, various thermoplastic resins such as soft polyvinyl chloride, styrene, olefin, and polyester are preferably used. Not only a resin material but also a woven fabric, a nonwoven fabric, a knitted fabric, or the like, or a laminated material in which a resin sheet is bonded to them may be used.

  For the elastically deformable cushion layer, foamed materials such as soft polyurethane foam and other elastic materials are used. However, a large number of elastically deformable minute protrusions and elastically deformable rib shapes (thin plate shapes) are used. Various embodiments are possible, such as providing protrusions. The microprotrusions are preferably configured to be elastically deformed in one direction, for example, and are arranged according to a predetermined arrangement pattern such as a lattice shape so that the deformation directions (falling directions) thereof are different. Such protrusions can be provided integrally on the back surface of the surface layer material, for example, but can also be provided as a separate member from the surface layer material, for example, a plate-like shape disposed so as to be in close contact with the surface layer material or the substrate. It is also possible to employ a cushion material in which a large number of protrusions are provided on the part. When the cushion material is integrally fixed to the base material, the cushion material may be divided in the same manner as the base material and fixed separately to the first member and the second member of the base material.
