Abstract
A throttle control apparatus carries out electronic throttle control, wherein a throttle valve is opened and closed by a motor actuated in accordance with depression of an accelerator pedal. It includes an accelerator lever actuated by the accelerator pedal, a throttle lever provided with the throttle valve, a motor lever actuated by the motor so as to operate the throttle lever in a valve-opening direction and in a valve-closing direction, a limp home lever, and an urging spring for urging the motor lever and the throttle lever in the valve-closing direction. The limp home lever is held rotatably on the throttle lever so as to rotate to an engagement position where it can mechanically engage with the accelerator lever and to a siding position where it cannot mechanically engage therewith. The urging spring also actuates the limp home lever so as to rotate to the siding position when electronic throttle control is carried out by the motor, and actuates it so as to rotate to the engagement position when electronic throttle control is not carried out by the motor.
