ABSTRACT:
An elevator governor capable of setting first overspeeds different between a rising time and a descending time by a simple configuration and at a low cost without the need for electric power supply from the outside. For this purpose, a weight that is moved in a predetermined direction by receiving a centrifugal force according to a travel speed at the rising time and the descending time of a car, an elastic body urged by movement of the weight having received the centrifugal force, and an actuating device actuates a stop switch when the weight having received the centrifugal force moves to a predetermined position against an urging force of the elastic body are provided, and also a switching device driven by the rising/descending operation of the car is provided. By the switching device, the length of the elastic body at the time when the actuating devices actuates the stop switch is switched to a length different according to the rising/descending direction of the car.
