PROBLEM TO BE SOLVED: To prevent a skin material from forming a wrinkle at a bending part when putting stitches in the skin material by a sewing machine. SOLUTION: The skin material 50 comprises a surface layer 50A having flexibility and a lining 50B having a cushioning property and is provided with a thin-walled part 58 on a part continuing to a part corresponding to the bending part 56. The thin-walled part 58 is formed so that thickness of the lining 50B is gradually made thinner toward the bending part 56 and smallest at the bending part 56. COPYRIGHT: (C)2011,JPO&INPIT
