油圧緩衝器のばね荷重調整装置。 The vehicle body side tube and the wheel side tube are slidably fitted together, the damper cylinder stands up from the lower part of the wheel side tube, and a suspension spring is interposed between the vehicle body side tube and the damper cylinder, so that the vehicle body side tube and the damper cylinder In the hydraulic shock absorber that constantly urges the piston rod inside the tube in the direction of extension, a cap is screwed onto the upper part of the tube on the vehicle body side, and an adjustment rod is placed in the central hollow part of the cap so that it can move freely in the rotational and axial directions. The cap consists of a main body and a barrel having a width across flats provided at the lower part of the main body, the upper part of the piston rod is fixed to the center of the lower part of the barrel, and a radial through hole is formed in the middle of the barrel. A washer that is movable in the axial direction is inserted into the body through this through hole, the lower end of the adjustment rod is brought into contact with the upper surface of the washer body, and a seat portion protruding from the outer periphery of the washer body is inserted into the through hole. 1. A spring load adjustment device for a hydraulic shock absorber, characterized in that the lower surface of the seat portion supports the upper part of the suspension spring directly or through a spacer by protruding further outward.
