一定に保つようにしたことを特徴とする緩衝装置。A piston tube is slidably inserted into the cylinder portion, a free piston is provided which separates the inside of the piston tube into an oil chamber and a compressed gas chamber, and a free piston is provided at the center and peripheral portions of the bottom plate of the piston tube. It is equipped with an orifice throttle hole and an orifice hole that allow the flow of hydraulic oil between the chamber and the oil chamber of the cylinder part, and a leaf spring having a spherical surface that opens and closes the orifice throttle hole according to the differential pressure between the oil chambers. 2. A shock absorber, characterized in that the differential pressure in each of the oil chambers is kept constant despite changes in the relative speed of the piston to the cylinder.
