Abstract

PURPOSE: To lock the brake inoperative unless required by providing a return device, which provides a rotational force in a direction opposite to the direction of braking action and a force in a direction opposite to the direction toward the brake section at the time of the braking operation.
CONSTITUTION: A coil return spring 19, which provides a torsional force and an urging force, that is, a force tending to cause rotation of a brake shoe 17 in a direction of opening the brake and a force tending to force the brake shoe 17 in a direction opposite to the direction toward a brake wheel 12, is mounted on the outer periphery of a cylindrical section of the brake shoe 17. The force of the return spring 19 may be very small compared to the rotational force exerted to the brake hole 17 due to friction between a centrifugal piece 15 at a dangerous rotational speed and a cylindrical inner peripheral surface of the brake shoe 17. by the provision of this return spring 19, a safety brake device 7 will not be operated unless a dangerous rotational speed is reached by a shaft 8 which is to be braked.
