動装置。An engine valve drive device comprising: an electromagnetic actuator that is energized to open a valve in accordance with the operating state of the engine; and a return spring that closes the valve when the electromagnetic actuator is turned off. A cam is provided for opening the valve within the opening timing of the electromagnetic actuator for the valve and within a range smaller than the amount of actuation of the valve by the electromagnetic actuator, and this cam is driven by an engine. An engine valve drive device characterized by:
