ABSTRACT:
A throttle opening control actuator is provided between a throttle (2) which is regularly urged by a return spring (5) in a direction for decreasing its opening in order to regulate engine output of a vehicle and an acceleration pedal (1) which is coupled to the throttle (2) by a cable (7). The throttle opening control actuator comprises a pump (17), a cylinder (10), a piston (11), a movable element (13) which is fixed to the piston (11), an opening direction contact part (8) which is forcibly pushed by the movable element (13) in a direction for increasing throttle opening upon displacement of the movable element (13) in one direction, a closing direction contact part (9) which is forcibly pushed by the movable element (13) in a direction for decreasing throttle opening upon displacement of the movable element (13) in the other direction and an electrical switch (23) for electrically detecting the state of contact between the movable element (13) and the opening direction contact part (8) and that between the movable element (13) and the closing direction contact part (9).
