On a sole plate, the foot is placed detachably, and a tilting mechanism is provided between the sole plate and the base. Ends of a first link and a second link are coupled to the front part of the sole plate and the base, respectively, while other ends are coupled to a first nut. Ends of a third link and a fourth link are coupled to the rear part of the sole plate and the base, respectively, while other ends are coupled to a second nut. A screw rod is inserted in the first and second nuts, and a link drive is provided in the middle of the screw rod. The link drive is coupled to the base, and rotates the screw rod about the axial line.
