PROBLEM TO BE SOLVED: To provide a hydraulic pressure buffering device that can vary an attenuation force due to a frictional force according to an amplitude.SOLUTION: A hydraulic pressure buffering device comprises: an inner cylinder 12 for storing oil; a piston rod 20 and a pressure absorption part 40 moving in the inner cylinder 12 in an axial direction; a free piston 55 and a friction member 57 provided on an inner periphery of the inner cylinder 1 slidably in the axial direction; and a first spring 51 and a second spring 52 connected to the free piston 55 and the friction member 57, and the piston rod 20 (the pressure absorbing part 40), and shrunk together with axial movement of a member for moving the piston rod 20, so as to move the free piston 55 and the friction member 57. |
