Throttle valve control apparatus for vehicles.

摘要

A throttle valve control apparatus (200) comprises a throttle valve element (5) supported on a valve shaft (2), a wire (8) for transferring a force of an accelerator operation part (50) to the throttle valve element (5), a motor (30) for driving the throttle valve (5), and a stopper member for transferring a driving force of the motor (30) to the valve shaft (2). The stopper member has a gear part (32) driven by the motor (30) and a restraint part for restraining an opening degree of the throttle valve (5). A notch is provided nearby the restraint part. The driving force of the motor (30) is transferred from the gear part (32) to the stopper member at the time of traction control. The restraint part of the stopper member thus drives the throttle valve element (5) in the close direction. The notch prevents the stopper member from coming in contact with the valve shaft.
