PROBLEM TO BE SOLVED: To prevent delamination of laminated textiles when partially increasing strength or rigidness in a shell type frame.SOLUTION: A back pan 60 includes a textile 61 weaved by crossing a warp and a weft, and resin molded by impregnating and solidifying the textile 61. The textile 61 includes a first weave texture part 61X and second weave texture parts 61A, 61B, and 61C which are continuously weaved. The second weave texture parts 61A, 61B, and 61C have a larger volume of fibers included per unit area than the first weave texture part 61X. The second weave texture parts 61A, 61B, and 61C are arranged and molded in parts (shoulder part central part 60A, lumbar part 60B, and side standing wall part 60d) which require high strength or high rigidness in the back pan 60. |
