Abstract: A hood (1) is provided such that opening states of right and left sides can be independently adjusted. The hood (1) comprises a hood body (2), a front cover member (4) connected to the front edge of the hood body (2) to cover the front of a seat and a right side cover member (5) and a left side cover member (6) connected to the right and left side edges of the front cover member (4) to cover the right and left sides of the seat, respectively. The right and left side cover members (5) and (6) are folded so as to be overlapped on the front cover member (4). In addition, a laminated body (3) of the front cover member (4) and the right and left side cover members (5) and (6) are folded so as to be overlapped on the upper surface of the hood body (2).
