るロツカ・アーム構造。[Claims for Utility Model Registration] A valve that is opened and closed by a rocker arm in contact with a valve stem head, which is disposed on one side with respect to the fulcrum of the rocker arm, and which is located on one side of a cylinder. In a valve train system including a plurality of valves whose center lines in the lift direction intersect with each other when viewed from the arrangement direction, the substantial contact surface of the rocker arm that contacts the valve stem head is formed into a curved surface, A rocker arm structure characterized in that the center of this curved surface is located at approximately the same position as the intersection point where the lift direction center lines of the valve intersect.
