<p>There is provided an elevator governor that is capable of setting first overspeeds different between the rising time and the 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 the travel speed at the rising time and the descending time of a car, an elastic body that is urged by the movement of the weight having received the centrifugal force, and an actuating means for actuating a stop switch when the weight having received the centrifugal force moves to a predetermined position against the urging force of the elastic body are provided, and also a switching means that is driven by the rising/descending operation of the car is provided. By this switching means, the length of the elastic body at the time when the actuating means actuates the stop switch is switched to a length different according to the rising/descending direction of the car.</p> |
