Claims

[Scope of utility model registration request]

a shock absorber body; a defining member provided in the shock absorber body and defining two oil chambers within the shock absorber body;
An oil passage formed in the defining member and communicating between the oil chambers; and an oil passage provided on one side of the defining member so as to cover one side of the oil passage, and communicating with each oil chamber through the oil passage. a check valve element that allows oil to flow in one direction between the two and prevents flow in the opposite direction; and a spring that normally biases the check valve element toward one side of the defining member in the valve-closing direction. and a spring seat for pressing the spring, wherein the check valve body has an integrally formed tongue piece that protrudes toward the spring seat and is elastically deformable, and the tongue piece allows the spring to be pressed down. A hydraulic shock absorber characterized by comprising:
