る油圧緩衝器。A cylinder filled with oil fluid and closed at both ends by a lid member, a piston slidably provided in the cylinder, a rod connected to the piston and guided by the lid member, and a cylinder formed by the piston. Two pressure chambers defined within the cylinder, a resistance force generating mechanism provided at a location where oil moves between the two pressure chambers, a gas-liquid chamber provided above the cylinder, and a gas-liquid chamber provided above the cylinder; A passage having a check valve that connects the liquid chamber and both pressure chambers separately and allows the oil liquid to flow from the gas-liquid chamber to the pressure chamber, and a passage that connects the gas-liquid chamber and both pressure chambers separately to reduce the resistance. A hydraulic shock absorber consisting of a passageway with a restriction that has a greater resistance than the generating mechanism.
