One end of a blade in a longitudinal direction thereof includes a first support rotatably supported by the first frame, and a second support rotatably supported by the second frame. The first support and the second support are disposed along a widthwise direction of the blade. Another end of the blade in the longitudinal direction thereof includes a third support rotatably supported by the first frame, and a fourth support rotatably supported by the second frame. The third support and the fourth support are disposed along the widthwise direction of the blade.
