いることを特徴とする内燃機関の動弁機構。(1) A first bushing is fitted onto the rocker shaft eccentrically downward on the Y-Y line passing through the axis with respect to the axis of the rocker shaft, and furthermore, the first bushing is fitted onto the first bushing. A second bushing is fitted and inserted eccentrically on the Y-Y line in the same direction as the eccentric direction of the first bushing with respect to the axis, and a rocker arm is loosely inserted onto the second bushing, and is connected to the first bushing. In the valve operating mechanism for an internal combustion engine, the valve operating mechanism for an internal combustion engine is configured to separate the rocker arm from the valve by rotating and controlling the second bushings at the same angle with respect to the axis of the rocker shaft in mutually opposite directions at the same time. Two links are provided which respectively interlock with the first bushing and the second bushing, the other ends of each link are connected at the same fulcrum, the same fulcrum is connected to the piston rod of the air cylinder, and the same fulcrum of each link is connected to the piston rod of the air cylinder. A support member is provided on the piston rod near the air cylinder, an elastic body is disposed between the support member and the lower outer wall of the air cylinder, and a space is formed by sealing compressed fluid in the elastic body. A valve mechanism for an internal combustion engine characterized by:
