ルクが発生しないよう工夫されている。 In the brake device B shown in FIG. 4, the braking member 31a of the brake lever 31 brakes the rotating body 1 by coming into pressure contact with the rotating body 1 by the urging force of the spring 32. The brake lever 31 in FIG. 4 is provided with a substantially U-shaped elastic deformation permitting portion 31b, and when braking the rotation of the rotating body 1 in the direction of arrow A (brake biting direction), an excessive braking torque is generated. It has been devised to prevent this from occurring.

点があつた。<Problems to be solved by the invention> In general, the braking torque in the biting direction of the brake is not stable, and excessive braking torque is sometimes applied. The brake device shown in FIG. 4 was devised to compensate for this drawback, but since the elastic deformation allowing portion 31b is simply formed in a U-shape, the braking member 31a does not touch the rotating body 1. As soon as they come into contact with each other, they begin to deform, and the spring constant becomes high, so the above-mentioned drawbacks cannot be fully compensated for.
