To activate the detection switch 31. When the speed further increases, the safety lever 32 is kicked and rotated, and the stopper 3 is rotated.
5 is released, the safety rod 33 moves to the right,
The lift lever 37 is rotated clockwise. As a result, the lift rod 38 is pulled up to operate the safety device, and at the same time, the other safety device is also operated via the connecting rod 37a to mechanically stop the car 1.

There has been a problem that accurate speed detection may be difficult due to an installation error of the guide rail 3 or the like. As another conventional example, the pulley 22 of the governor is directly connected to the guide rail 3.
However, there is a problem that the rotation of the pulley 22 may be inaccurate because it is directly affected by the step of the joint of the guide rail 3 or the like.
