The connection member includes an upper end portion rotatably connected to the interconnection section. The connection member includes a shaft section and the upper rear leg includes a shaft holding portion for holding the shaft section. The shaft holding portion includes a shaft holding surface for holding a lower end portion of the shaft section, a dislodgement prevention portion, and a guide portion inclined downward forward to guide the shaft section to the shaft holding surface.
