Abstract
In an emergency brake mechanism of the present invention, a rotation input shaft is increased in rotation speed by a planetary set-up gear to centrifuge weights. Through the action of the centrifugal force of the weights, linings of the brake shoes are brought into press-contact with a fixed portion to reduce rotation of the rotation input shaft, such that a large braking power is produced for a compact emergency brake mechanism.
