  As described above, the ottoman 4 rotates within a rotation angle range of 10 to 20 degrees. When the ottoman 4 rotates upwardly within this rotation angle range, a motor (not shown) in the actuator 11 moves in the reverse direction. , And the rotational force is transmitted to the movable cylinder portion 11C. In FIG. 7B, the movable cylinder portion 11C slides in the direction of the arrow B2. At this time, since the slider 11D and the movable cylinder part 11C are not fixed, the force acting on the slider 11D from the movable cylinder part 11C does not work, and only the movable cylinder part 11C tries to slide in the arrow B2 direction. The weight of the ottoman 4 and the user's leg acts on the slider 11D as a counterclockwise moment about the pin 10. When this moment acts on the slider 11D, the slider 11D has the projection 11F in contact with one side of the long hole 11E of the movable cylinder part 11C, that is, the arrow B2 together with the movable cylinder part 11C while following the movable cylinder part 11C. Slide in the direction. When the ottoman 4 is rotated using the weights of the ottoman 4 and the user's legs in this manner, the stretch with respect to the user's legs is compared with the case where the ottoman 4 is mechanically rotated directly by the motor in the actuator 11.
