Claims

[Scope of utility model registration request]

(1) In a hydraulic shock absorber in which damping force is adjusted by the switching operation of a drive device such as a solenoid that is electrically driven and controlled by a changeover switch, a power output amplification device is included in the drive circuit of the drive device. A hydraulic shock absorber characterized by being provided with.

(2) Compare the storage memory that stores the damping force adjustment state by the drive device in the control unit of the drive device, the switching operation state of the changeover switch, and the stored contents of the memory 5-, so that these two correspond to each other. The shock absorber according to claim 1, which is a registered utility model, further comprising an automatic control device that controls the drive device so as to automatically switch the damping force adjustment state.

(3) The shock absorber according to claim 1, wherein the control section of the drive device is provided with a display that detects and displays the adjustment state of the damping force based on changes in the current applied to the drive device.
