Abstract: A vehicle height adjustment apparatus includes a rear wheel suspension spring that is disposed between a vehicle body and a tire wheel of a vehicle; a rear wheel damper that undergoes an extensional and contractional operation so as to move working oil to dampen vibration of the spring; a support member that supports one end portion of the spring, and moves relative to the damper to change the length of the spring; a jack chamber into which the working oil causing the support member to move relative to the damper flows by the extensional and contractional operation of the damper; a rear wheel electromagnetic valve that adjusts the amount of the working oil flowing into the jack chamber by the degree of opening of the electromagnetic valve; and control device that controls the degree of opening of the electromagnetic valve based on a weight exerted on the vehicle.

Abstract: An object of the present invention is to ensure that, during adjustment of a spring load by an adjuster, total fully-stretched lengths of an outer tube and an inner tube remain unchanged and the adjuster is prevented from protruding from an upper surface of a cap. In a hydraulic shock absorber 10, a spring load adjusting device 30 is configured such that an adjuster 31 is provided at an upper end portion of a vehicle body side tube 11, a push rod 33 that is moved up and down by the adjuster 31 is penetrated into a hollow portion of a hollow rod 23, a suspension spring 35 is pressurized by the push rod 33 that protrudes from the hollow portion of the hollow rod 23 to the inside of a wheel side tube 12, and the spring load of the suspension spring 35 can be adjusted by the up-and-down motion of the push rod 33 caused by the adjuster 31.
