The stepping motor and the throttle valve are connected by a link mechanism, and the link mechanism includes a first arm having one end fixed to the throttle shaft and disposed parallel to the throttle valve, and a first arm having one end fixed to the throttle shaft. A second arm that is fixed to the shaft of the stepping motor and rotates is connected to the other ends of the first and second arms by a rotatable link, and the first arm is connected to the throttle. A throttle valve drive device for an internal combustion engine, characterized in that the throttle valve drive device is fixed to the throttle shaft in the same phase as the valve.
