ABSTRACT:
A throttle valve controller configured to control opening and closing of a throttle valve disposed in an air-intake passage of a throttle body coupled to an engine, including an input member that is rotatable in association with a rider's hand operation, a power transmission device with an input part thereof coupled to the input member, an output member that is coupled to an output part of the power transmission device and causes the throttle valve to rotate in association therewith, an actuator configured to drive the power transmission device to cause the output member to rotate relative to the input member to change a rotational ratio of the output member to the input member independently of the hand operation, and a movable stopper configured to change and restrict a rotational range of the input member in a closing direction of the throttle valve.
