In a wall body structure of an automobile vehicle body, an outer skin (24) and an inner skin (25) of a wall body (16) of an FRP automobile cabin (11) are provided with a plurality of continuous fiber layers that are layered with different fiber oriented angles of continuous fibers with respect to the longitudinal direction of the outer and inner skins. In the outer skin (24), the fiber oriented angle of a pair of surface layers is greater than the fiber oriented angle of an inner layer. Thus, the outer skin (24) has lower strength but higher ductility than the inner skin (25), and the inner skin (25) has higher strength but lower ductility. As a result, when localized collision load is applied to the outer skin (24), the outer skin (24) is readily deformed, transmitting the collision load to the inner skin (25) in a distributed manner. Accordingly, the localized collision load can be efficiently absorbed by the outer skin (24) and the inner skin (25) cooperating together, whereby destruction of the wall body (16) can be suppressed. |
