関の動弁装置。 In an internal combustion engine having at least one of two intake valves and two exhaust valves for each cylinder, a swinging fulcrum part of one end of a swing arm that follows a cam of a camshaft is supported so that the position of the swinging fulcrum part can be adjusted. A pair of valves, which are supported in a swingable manner by being mounted on the support member, are extended from the swinging fulcrum side toward the valve shaft ends of the two valve shafts of the same type, and are in contact with the valve shaft ends. A valve operating system for an internal combustion engine, characterized in that valve springs forming arm portions and urging the two valves of the same type to close are wound in different directions.
