Abstract
A swinging motion reducing apparatus includes a flywheel 20, a gimbal 11, a gimbal supporting section 12, a damper 13 and a lock mechanism 14. The gimbal 11 rotatably supports the flywheel 20. The gimbal supporting section 12 supports the gimbal 11 through a gimbal shaft 15 such that the gimbal 11 can swing. The damper 13 brakes a swinging motion of the gimbal 11. The lock mechanism 14 locks a swinging motion of the gimbal 11.
