装置。 A main throttle valve whose opening degree is controlled according to the amount of depression of the accelerator pedal and a sub-throttle valve whose opening degree is controlled independently of the accelerator pedal are arranged in the intake passage of the engine. The traction control device is capable of controlling engine output torque independently of the accelerator pedal by controlling the opening degree, and the traction control device includes a drive mechanism that drives the sub-throttle valve, and a drive mechanism that biases the sub-throttle valve in the opening direction. and a valve opening speed control means that cooperates with the urging means to gradually open the sub-throttle valve from a predetermined opening degree to a fully open position when the drive mechanism is abnormal. Traction control device.
