Claims

[Scope of utility model registration request]

In a hydraulic shock absorber, a damping force generating device is installed in an oil passage communicating between a reservoir chamber and a cylinder chamber, which compensates for the amount of oil corresponding to the change in cylinder internal volume due to the movement of a piston rod in and out. consists of a valve case and an inner cylinder provided in the valve case, a gap passage is formed on the inner periphery of the valve case, an inner pipe passage is formed in the inner cylinder, and a pressure side is formed between the independent inner pipe passage and the gap passage. A damping force generating device for a hydraulic shock absorber, characterized in that a valve and an expansion side valve are respectively disposed, and the expansion side valve is a non-return valve arranged directly on an end seat of an inner cylinder so as to be freely openable and closable.
