動弁装置。 In order to swing the rocker arm that is swingably supported by the support means, a drive cam that responds to the rotation of the engine is brought into sliding contact with the rocker arm, and is able to open and close the engine body while being biased by a spring in the valve closing direction. A driven cam that is in sliding contact with the rocker arm is interlocked and connected to the head of the supported engine valve, and a biasing force is provided between the engine body and the driven cam that exerts a biasing force in the direction of sliding the driven cam into sliding contact with the rocker arm. In a valve train for an internal combustion engine in which a force means is interposed, a drive cam is slidably contacted with a longitudinally intermediate portion of a rocker arm, and is capable of displacing a fulcrum position that supports the rocker arm. A driven cam formed in the engine body and supported in an axially movable manner by the engine body is disposed at a position corresponding to both ends of the rocker arm on the opposite side of the rocker arm from the drive cam. Engine valve gear.
