ABSTRACT:
A brake apparatus applies a braking force from a stationary member to a moving member adapted to move relative to the stationary member. Magnets are arranged on the stationary member along the linear motion or rotational direction of the moving member and magnets are arranged on the moving member so that the stationary side magnets face the moving side magnets. When magnetic attractive/repulsive forces between the magnets on the moving and stationary members act in a direction to accelerate the moving member, the magnets on either one side are allowed to escape in the same direction. When magnetic attractive/repulsive forces act in a direction to decelerate the moving member, the magnets are restrained from movement in the same direction. This brake avoids any temperature rise due to local heat generation during braking.
