PROBLEM TO BE SOLVED: To provide technology for bringing a vehicle height to a target vehicle height even when a state of raising the vehicle height and a state of lowering the vehicle height are switched at a time when an operation amount of an actuator, which increases according to a supplied current amount, becomes a predetermined amount.SOLUTION: A vehicle height adjustment device comprises: a front fork having a front wheel side flow passage switching unit in which an operation amount increases according to a current amount, and a front wheel side relative position detection part for detecting a relative position between a vehicle body and an axle, and changing the relative position according to the operation position; and a control device for adjusting a vehicle height by controlling a current to be supplied to the front wheel side flow passage switching unit. The front fork, when the operation amount of the flow passage switching unit is a predetermined amount or less, is put in the state of raising the vehicle height, and when the operation amount of the flow passage switching unit is larger than the predetermined amount, is put in the state of lowering the vehicle height. The control device determines a target current based on a map in which a deviation between a target value of the relative position and a detection value detected by the front wheel side relative position detection part is made to correspond to a target current to be supplied to the front wheel side flow passage switching unit.SELECTED DRAWING: Figure 14

    【課題】供給される電流量に応じて大きくなるアクチュエータの作動量が所定量になるのを境にして車高を上昇させる状態と下降させる状態とに切り替わる場合においても、車高を目標車高にすることができる技術を提供する。【解決手段】電流量に応じて作動量が大きくなる前輪側流路切替ユニットと、車両本体と車軸との相対位置を検出する前輪側相対位置検出部とを有し、作動量に応じて相対位置を変更するフロントフォークと、前輪側流路切替ユニットに供給する電流を制御することで車高を制御する制御装置とを備え、フロントフォークは、流路切替ユニットの作動量が所定量以下である場合には、車高を上昇させる状態となり、作動量が所定量よりも大きい場合には下降させる状態となり、制御装置は、相対位置の目標値と前輪側相対位置検出部が検出した検出値との偏差と、前輪側流路切替ユニットに供給する目標電流とを対応させたマップに基づいて目標電流を決定する。【選択図】図14
