<p>A sheave shaft is rotatably supported by a pedestal fixed to a car. The pedestal is provided with a speed governor sheave around which a speed governor rope stretched vertically within a hoistway is wound. The speed governor sheave is provided with a flyweight, which is displaced from a normal position to a trip position due to a centrifugal force resulting from rotation of the speed governor sheave. The sheave shaft is provided with an operational member displaceable in an axial direction of the sheave shaft. The normal position of the flyweight is adjusted through displacement of the operational member with respect to the sheave shaft. A cam member, which is inclined with respect to a direction in which the car is moved, is provided within the hoistway. The car is provided with an operational force transmitting member for displacing the operational member. The operational force transmitting member has an engaging portion engaged with the operational member in the axial direction of the sheave shaft, and a driven portion coupled to the engaging portion to be guided along the cam member through a movement of the car.</p> |
