PURPOSE:To provide a buffer device which may exhibit a large buffering capacity even in a small space, by employing a telescopic cylinder. CONSTITUTION:A cylinder 3 is designed to be inserted into a cylinder 4, and the cylinder 4 is designed to be inserted into a cylinder 5. Oil 10 is filled in the cylinders 3, 4 and 5, and is designed to be fed through a valve 11 into an oil reservoir 9. When the cylinders 3, 4 and 5 are biased to be contracted by a piston 1 upon receiving impact, the oil 10 is fed into the oil reservoir 9 to show a buffering action. Further, upon receiving a small impact, a reversible buffering action may be effected by a spring 3. |
