Abstract
The present invention provides a crash stop which is capable of adjusting shock absorptivity by employing the same elastic material and where the mounting and demounting operations are easy. A metal pin has a recess in its intermediate portion. An elastic body has three blade portions. In a crash stop, the metal pin is press fitted into the pin inserting hole of the elastic body, and the portion between the support portion and the knob portion of the metal pin is covered with the elastic body. In the boundary between the intermediate portion of the metal pin and the elastic body, a cavity is formed. The support portion is fitted into the crash stop support hole of the base so that it can be freely pulled out and inserted. At this time, the upper end of the blade portion contacts the inner side surface of the crash stop inserting hole of the upper yoke and is contracted, and by the frictional force generated between the crash stop inserting hole and the upper end of the blade portion, the crash stop is locked. The abutting shock of the stopper arm of an actuator is absorbed with cooperation of the elastic body and the cavity.
