Abstract: PROBLEM TO BE SOLVED: To provide a crash stop capable of adjusting a shock absorbability by using the same elastic material and also whose attaching and detaching work is easy. SOLUTION: A metallic pin 41 has a recessed part 41f at an intermediate part 41a. An elastic body 42 has three impellers 43 (43a-43c). A crash stop 40 is a stop in which the metallic pin 41 is force-fitted into the pin inserting hole of the elastic body 42 and the part between the supporting part 41d and the knob part 41e of the metallic pin 41 is covered with the elastic body 42. A void 45 is formed at the boundary between the intermediate part 41a of the metallic pin 41 and the elastic body 42. Here, the supporting part 41d is made to be insertingly engaged with the crash stop supporting hole 10d provided in a base 10a freely pullingly and insertingly and tip ends 44 (44a-44c) of the impellers are made to be brought into internal contact with a crash stop inserting port 6c of an upper yoke 6 by being narrowed and the crash stop 40 is fixed buy this frictional force. Abutting shocks of stoppers (23a-23b) of an actuator are absorbed by the cooperative work of the elastic body 42 and the void 45.
