Abstract:
1. 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, the throttle valve controller comprising: an input member including a rotatable hand grip 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 rider's 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; wherein the movable stopper is configured to be able to be switched from a restricting state that restricts the rotational range of the input member to a non-restricting state that does not contact a component that is rotatable in association with a rider's hand operation, and therefore does not restrict the rotational range.
