The valve body is opened and closed by displacing the valve body via the rotation transmission mechanism, and the rotating piece is displaced by the rotation of the motor, and the detecting means detects the rotating piece, thereby opening and closing the valve body. A control valve with a valve body position detection mechanism, characterized in that it is configured to detect the position of a valve body. (2) Scope of Utility Model Registration The control valve according to claim 1, wherein the motor is a stepping motor, and is equipped with a valve body position detection mechanism. (3) Scope of Utility Model Registration The control valve according to claim 1, wherein the detection means is a control valve with a valve body position detection mechanism consisting of a proximity switch. (4) Utility Model Registration The control valve according to claim 1, in which the rotation transmission mechanism is a crank mechanism, is equipped with a valve body position detection mechanism.
