摘要： The hydraulic damping device includes: a cylinder storing fluid; a piston configured to form a channel through which the fluid flows along with relative movement of a rod relative to the cylinder in a specific direction; a valve having elasticity, the valve being configured to open and close the channel in the piston; a movement permitting part configured to permit the valve to move between a contact position and a spaced position, the contact position being a position where the valve contacts the piston, the spaced position being a position where the valve is spaced from the piston; a restricting part configured to restrict bending of the valve at the spaced position; and an imparting part having elasticity, the imparting part being configured to impart, to the valve, a load that is uneven in a circumferential direction of the valve and directed toward the piston.

摘要： A hydraulic pressure cushioning device includes: a cylinder; a rod movably provided in the cylinder; a first piston valve section that is provided on the rod. The first piston valve section includes: a first piston member and a second piston member that form a channel; and a single first damping valve with which a first flow of the fluid from the first side to the second side in the channel and a second flow of the fluid from the second side to the first side in the channel are controlled; a bypass path which differs from the channel; and a free piston provided on the rod in such a manner that a flow of the fluid is switched between the channel and the bypass path in accordance with a movement position of the rod.
