内燃機関の動弁装置。 In a valve operating system for an internal combustion engine that drives a valve via a rocker arm that is swingably attached to the rocker shaft by a cam, the tightening direction of the bolt that fixes the rocker shaft to the bracket is changed to the rocker shaft when the valve is seated at maximum rotation of the engine. A valve train for an internal combustion engine, characterized in that the direction of the force acting on the valve is made to match the direction of the force acting on the valve.
