Abstract

PURPOSE:To improve a damping characteristic and response quality for the above described shock absorber used in a bicycle where damping force is arranged variable in accordance with a telescopic position, by widely forming the oil chamber of a control valve and increasing a prssure change surface of the control valve. CONSTITUTION:If a shock absorber is contractibly operated to contact its inner tube 2, pressure in an oil chamber A is increased. Its pressure oil passes through an oil feed pipe 28 to enter an oil chamber 34, press a pressure change surface and move a control valve 30 leftward against a spring 19, then an orifice 38A is throttled by an inlet hole 26. Accordingly, maximum damping force is obtained at maximum contraction time. On the contrary, if the inner tube 2 is extended, pressure in the oil chamber 34 is decreased, and the control valve 30 is moved rightward by resilient force of the spring 19, then the orifice 38A is opened by the inlet hole 26, thus damping force can be gradually reduced.
