PROBLEM TO BE SOLVED: To provide a buffer constituted to increase resistance applied to a piston when the piston reaches a prescribed position in a cylinder in a compressing motion.SOLUTION: A buffer includes a cylinder 3 accommodating a hydraulic oil, a piston 4 disposed in the cylinder, and a rod 5 retaining the piston, and further includes a friction member 42 disposed at one end side of the cylinder with respect to the piston and slidable on an inner peripheral face of the cylinder, and elastic means 43 disposed between the friction member and one end of the cylinder. A reaction body 48 is constituted by connecting one end of the elastic means and one end of the cylinder, and connecting the other end of the elastic means and the friction member.SELECTED DRAWING: Figure 3 |
