A cloth having a larger area than that of the bottom of the main body is pierced with the pile to lock the same to the opposite sides of said main body, and the cloth is positively retained on the opposite sides of the main body by the stopper arm portions of the fasteners, so that the bottom of the main body is covered with the cloth.
