Abstract
A brake mechanism for a rotator has a brake arm rotatably supported, a brake pad, a spring exerting force to the brake arm in a direction in which the brake pad is brought into contact with the rotator, and a rotation restriction pin for restricting a range of the rotation of the brake arm. When the rotator rotates in a direction, in which force for causing the brake arm to be brought toward the pin is exerted to the brake arm, the automatic biting condition is satisfied at the rotation braking start point, subsequently the brake arm comes into contact with the pin, and the relieving condition is satisfied. On the other hand, when the rotator rotates in an opposite direction, in which force against the force exerted to the brake arm by the spring is exerted to the brake arm, the relieving condition is satisfied at the rotation braking start point, and then the relieving condition is satisfied also when the rotator stops rotating.
