PROBLEM TO BE SOLVED: To provide a guide device for elevator which is small-sized, and which can exert both a function of an active guide and a function of an attenuation device effectively.SOLUTION: A guide device for elevator is provided at upper/lower/left/right sides of an elevator car, and it includes a guide roller supported by a guide rail on a structure side in contact. It includes: a lever mounted on a base fixed to the car in a manner rotatable by a first rotary shaft; an attenuation device provided at one end side of the first rotary shaft of the lever; a second rotary shaft provided on the other end side of the first rotary shaft of the lever and for mounting the guide roller rotatably; and an active guide provided at the other end side of the first rotary shaft of the lever farther than the second rotary shaft, and for rotating the lever by being imparted a thrust in a direction for suppressing vibration generated in the car.SELECTED DRAWING: Figure 1 |
