A self-pumping vehicle height adjustment device for a hydraulic shock absorber for a motorcycle having a switching valve for switching the vehicle height between an up position and a down position on the road, the oil path being parallel to the oil path of the vehicle height adjustment device. A spool valve is provided as a common switching valve for these parallel oil passages, and a first check valve that allows flow only from upstream to downstream in order to increase the vehicle height is installed in one of the parallel oil passages downstream of the spool valve. At the same time, a second check valve is provided in the other oil passage that only allows flow from downstream to upstream to lower the vehicle height when activated by the spool valve, and a flexible wire is connected to the spool valve. A self-pump type vehicle height adjustment device characterized by being able to be remotely controlled. (2) Furthermore, a jack chamber is provided in a second hydraulic shock absorber different from the first hydraulic shock absorber that performs the pumping action, and this jack chamber is connected to the first check valve downstream of the first and second check valves. 2. The self-pump vehicle height adjustment device according to claim 1, wherein the self-pump vehicle height adjustment device communicates with a jack chamber of a hydraulic shock absorber.
