A multi-axial crank is pivotally supported on the frame body. A lower end of each handle is coupled to one of two crank axles of the multi-axial crank. A rotation of the multi-axial crank makes a back and forth movement of the lower ends of the handles, and the back and forth movement of the lower ends of the handles makes a rotation of the multi-axial crank.
