PURPOSE: To simplify structure by defining a first chamber of a body and a guide means of a second end of the thrust rod inside the body by a tubular membrane jointly with a bush, a thrust rod and a piston. CONSTITUTION: In a compression stroke, a thrust rod 8 moves to the right to slide a piston 4 to the right in a bush 2 against a compression spring 5. In this process, liquid moves from a chamber B to a chamber A through a small diameter hole 4c of the piston 4 to generate braking action proportional to the moving speed. A free part of a membrane 7, that is, a part formed of parts 7b, 7c is deformed, and the part 7b is folded in S-shape as the end 8a of the thrust rod 8 moves to the right. When force is no longer applied, the tubular membrane 7 is loosened to return into its original shape. |
