PROBLEM TO BE SOLVED: To achieve impact damping during high-speed stroke ending when relative movement occurs between a fixed side and a movable side and prevent the unreasonable acceleration of reversing operation during reverse movement. SOLUTION: A spring member 4 has one end locked to a spring guide 7 in slide contact with the fixed side 2, while an energizing body 8 is arranged between the spring guide 7 and the fixed side 2 and adapted to be deformed during the slide of the spring guide 7. The energizing body 8 has a capacity room R formed between the fixed side 2 and itself for increasing/reducing its capacity during the slide of the spring guide 7. The capacity room R is communicated with the outside via a restriction flow path 7a formed in the spring guide 7 or between the spring guide 7 and the fixed side 2. COPYRIGHT: (C)2004,JPO |
