ル開度制御装置。[Claims for Utility Model Registration] The throttle valve is moved to a first idle up opening position that is more open than the idle opening position and a second idle up opening position that is more open than the first idle up opening position. a first drive signal for driving the throttle valve to the first idle up position; and a first drive signal for driving the throttle valve to the first idle up position; In the throttle opening control device, the throttle opening control device has a control means for selectively generating a second drive signal for driving the throttle valve to a position where the control means selectively generates a second drive signal for driving the throttle valve to a position where the control means generates a second drive signal for driving the throttle valve to occurs, and during deceleration after said steady running,
The second drive signal is canceled after a first predetermined time has elapsed, and the first drive signal is released after a second predetermined time has elapsed.
A throttle opening degree control device characterized by canceling a drive signal of.
