摘要：
In a cushion body structure of a car seat, which is made by fastening a skin material to a cushion material by using a planar fastening material, an impregnation layer made of a foamed body is not produced. In the cushion body structure, a planar fastening body (4) is integrally molded with a cushion material by shielding and clamping walls (22, 23) for preventing entry of a foaming solution in a molding die (20) of the cushion material (2,3), so that an opening is provided between the periphery of the planar fastening body and the side (3) of the cushion material, and a non-impregnation layer (7) is formed in the periphery.
