PROBLEM TO BE SOLVED: To provide a seat for vehicles which are obtained by forming all of parts constituting the seat of the same materials and makes the respective parts recyclable all together without disassembling and discriminating the parts by each of materials like heretofore. SOLUTION: The seat consists of a sheet pad 1, sheet cover 2 and shield 3 which are made of synthetic resins of the same material. The expansion rates of the seat pad 1 are partially varied in such a manner that the hardness of the areas requiring rigidity increases. Olefinic synthetic resins like, for example, polypropylene resins, are usable as the synthetic resins of the same material. COPYRIGHT: (C)2003,JPO
