全機構。 In addition to the main throttle valve that is linked to the accelerator pedal, it has a sub-throttle valve operated by an electric actuator, and when reducing engine drive, the opening degree of the sub-throttle valve is controlled to reduce engine output. In the traction control device, the traction control device includes a biasing member that biases the sub-throttle valve in the closing direction, a negative pressure actuator that operates the sub-throttle valve, and a negative pressure actuator that operates when the sub-throttle valve is normal. A sub-throttle valve comprising: a switching valve that introduces atmospheric air into a negative pressure chamber, and that introduces negative pressure downstream of the sub-throttle valve into the negative pressure chamber of the negative-pressure actuator when the sub-throttle valve is abnormal. safety mechanism.
