ABSTRACT:
A braking device for an elevator winding machine generates a braking force by contacting a rotary body driven by a rotary shaft of the winding machine with a brake section supported through the intermediary of an elastic body. The elastic body has a nonlinear elastic characteristic so that a starting shock to the passengers in the elevator car is prevented and the braking torque detecting accuracy is improved.
