Patent attributes
In a throttle device for a multipurpose internal combustion engine having a throttle valve, a throttle shaft connected to the throttle valve and an electric motor housed in a housing to move the throttle valve, both ends of a motor output shaft is configured to protrude from the housing in such a manner that the one end is connected to a power transmission mechanism, whilst the other end is inserted in a hollow boss formed in a fixing component of the motor, thereby ensuring no fluctuation to occur in the positional relation of the output shaft to the throttle shaft, while enabling to prevent friction from being generated in the power transmitting mechanism. In addition, a manual operating lever is provided to allow the engine to be easily started again even when the throttle valve is held nearly closed when the engine is stopped.
