Abstract
A throttle valve control apparatus comprises a throttle valve element supported on a valve shaft, a wire for transferring a force of an accelerator operation part to the throttle valve element, a motor for driving the throttle valve, and a stopper member for transferring a driving force of the motor to the valve shaft. The stopper member has a gear part driven by the motor and a restraint part for restraining an opening degree of the throttle valve. A notch is provided near the restraint part. The driving force of the motor is transferred from the gear part to the stopper member at the time of traction control. The restraint part of the stopper member thus drives the throttle valve element in the close direction. The notch prevents the stopper member from coming in contact with the valve shaft.
