A fluid pressure damper (100) is provided with: a damping valve (20) capable of changing damping characteristics in accordance with pilot pressure; and a pilot valve (30) that supplies a working fluid in the bottom-side chamber (1) or the rod-side chamber (2) as a pilot pressure to a pilot chamber (27) of the damper valve (20), the pilot valve (30) having: a first pilot chamber (31) into which the working fluid is introduced from the bottom-side chamber (1); and a second pilot chamber (32) that introduces a working fluid from the rod-side chamber (2), the pilot valve (30) supplies a pilot pressure to the pilot chamber (27) of the damper valve (20) when the fluid pressure damper (100) is in a non-telescopic operation, and the pilot valve (30) maintains the pilot pressure of the pilot chamber (27) of the damper valve (20) when the fluid pressure damper (100) is in a non-telescopic operation when the fluid pressure damper (100) is in a telescopic operation.

    流体压力缓冲器(100)具备:阻尼阀(20),其能够根据先导压力变更阻尼特性;以及先导阀(30),其将底侧室(1)或杆侧室(2)的工作流体作为先导压力向阻尼阀(20)的先导室(27)供给,先导阀(30)具有:第一先导室(31),其从底侧室(1)导入工作流体;以及第二先导室(32),其从杆侧室(2)导入工作流体,在流体压力缓冲器(100)为非伸缩动作时,先导阀(30)向阻尼阀(20)的先导室(27)供给先导压力,在流体压力缓冲器(100)为伸缩动作时,先导阀(30)保持流体压力缓冲器(100)为非伸缩动作时的阻尼阀(20)的先导室(27)的先导压力。
