Abstract

To provide a movement regulating device of an elevator car allowing for easily adjusting a mount position when a switch metal plate is mounted.SOLUTION: A movement regulating device 11 of an elevator car comprises: a fixed member 3 mounted on one of a hoistway and a car 2; a movable member 4 which is provided on the other one of the hoistway and the car 2, is formed with a rotary shaft on an end thereof, is rotatable between a car movement regulated position and a car movement allowable position, and is engaged with the fixed member 3 at the car movement regulated position; a switch 6 for detecting a state that the movable member is in the car movement regulated position; an attachment metal plate 7 holding the switch 6; and a detection object part which is provided on the rotary shaft side of the movable member 4, and is brought into contact with the switch 6 so as to cause the state that the movable member 4 is in the car movement regulated position to be detected. The movement regulating device of the elevator car further comprises a stopper part 10 which is provided projecting from the rotary shaft side along the longitudinal direction of the movable member 4, and is rotatable together with the movable member 4, and when the movable member 4 rotates toward the car movement regulated position, the stopper part abuts against the attachment metal plate 7 and also regulates the movable member 4 from further rotating toward the car movement regulated position side.SELECTED DRAWING: Figure 3
