摘要： A gas chamber (G) and a liquid chamber (R) are separated by a free piston (2) in a cylinder (1) of a hydraulic damper. The free piston (2) comprises a hollow main body (3), a metal bellows (4) which elongates and contracts according to a pressure balance between the gas chamber (G) and liquid chamber (R), and a stopper (8) fixed to the main body (3) for preventing the metal bellows (4) from elongating beyond a predetermined length. By compensating for variation in the capacity of the liquid chamber (R) caused by a displacement of the piston (10) in the cylinder (1) by elongation or contraction of the metal bellows (4), the damping characteristic of the damper is prevented from becoming unstable due to a frictional force acting on the free piston (2). The stopper (8) prevents excessive stress from being exerted on the metal bellows (4).
