とを特徴とする油圧緩衝器の減衰力調整機構。An oil passage 4 communicating with the piston front and rear oil chambers A and B is formed in the piston rod 1 to which the piston is fixed, and the damping force of the pulling stroke is variably adjusted at one end of the oil passage 4 that opens into the piston front oil chamber A. In the damping force adjustment mechanism of a hydraulic shock absorber, the damping force adjustment mechanism of a hydraulic shock absorber is formed by fitting a select valve 5 and fitting an adjustment member 7 for variably adjusting the damping force of the pushing stroke on the other end side opening to the rear oil chamber B of the piston. An oil passage 22 communicating from the piston rear oil chamber B to the oil passage 4 in the piston rod 1 is provided in the member 7 and the piston rod 1 that is in contact with the member 7, separately from the orifice of the adjustment member 7, and the oil passage 22 is provided with a drawing stroke. A damping force adjustment mechanism for a hydraulic shock absorber, characterized in that it is provided with a check valve 23 that opens with a push stroke and closes with a push stroke.
