A movable desk includes a cam, an elevation member, a brake portion, and a guide portion. The cam rotates in accordance with a rotation of the top panel. The elevation member, including one end swingably connected to the cam, is moved downward when the top panel is rotated to the in-use position, while being moved upward when the top panel is rotated to the storage position. The brake portion is swingably connected to the elevation member and contacts a floor surface when the top panel is in the in-use position thereby fixing at least one leg portion with respect to the floor surface. The guide portion abuts the brake portion thereby to bring the brake portion into contact with a predetermined position of the floor surface.
