ラツチ制御弁の最低油圧調整装置。[Scope of Claim for Utility Model Registration] A clutch control valve that outputs hydraulic pressure to a clutch according to a signal hydraulic pressure, comprising: a first spring that biases the valve body in the same direction as the signal hydraulic pressure; a second spring biased in an opposite direction and having a smaller spring load than the first spring; a return port to which output hydraulic pressure is returned to bias the valve body in a direction opposite to the signal hydraulic pressure; and a second spring. 1. A minimum hydraulic pressure adjustment device for a clutch control valve, comprising a movable member that can move in the axial direction in response to a reaction force, and a screw mechanism that can adjust the amount of movement of the movable member.
