ENGINE THROTTLE APPARATUS FOR VEHICLE

摘要

PURPOSE: An engine throttle device for a vehicle is provided to prevent a sudden acceleration caused by malfunction of an ECU(Engine Control Unit) because a rotation state of the throttle valve is controlled with mechanical displacement according to an operation state of an accelerator pedal. CONSTITUTION: An engine throttle device for a vehicle comprises a throttle valve(3), a rotating member(5), rotation-restricting unit(7), an accelerator pedal(9) and a displacement transmission unit(11). The throttle valve is rotated by torque from a motor. The rotating member is connected to a rotary shaft of the throttle valve. The rotation-restricting unit converts the rotating member into a rotatable state or a non-rotatable state by the mechanical displacement. The displacement transmission unit transfers the mechanical displacement of the accelerator pedal to the rotation-restricting unit.
