ることを特徴とする流体スプリング。 A fluid spring that partitions the fluid chamber by inserting a piston attached to a rod into a cylinder that forms a fluid chamber therein, and communicates both parts of the partitioned fluid chamber through an orifice formed in the piston. A circumferential groove is provided on the outer periphery of the piston in which an O-ring is fitted and is movably supported in the axial direction of the cylinder, and further, a circumferential groove is provided on a part of the outer periphery of the piston to cross the circumferential groove and to connect both sides of the gas chamber. A fluid spring characterized by forming a groove-shaped orifice that connects the parts and has a shape in which a flow path is narrowed by an O-ring located during an expansion operation, and a flow path is opened by an O-ring located during a contraction action. .
