Claims

[Scope of utility model registration request]

Each cylinder is provided with at least one of an intake valve and an exhaust valve, and one end of a swing arm is driven by a cam of a camshaft via a cam follower.
The support member is removably fixed to the cylinder head, and is swingably supported in an adjustable and rotatable manner, and extends from the swing fulcrum side toward the valve shaft ends of the two similar valves. It has a Y-shaped swing arm in which an arm part provided with a pair of flanges is brought into contact with the valve shaft end as a valve side follower, and the swing arm is connected to the head of the support member and the two valve shaft ends. A valve operating system for an internal combustion engine in which the camshaft is supported at three points on the camshaft, and when the camshaft rotates, the cam presses the cam follower of the swing arm, and the swing arm simultaneously opens and closes two valves of the same type. 1. A valve train for an internal combustion engine, characterized in that the roller cam follower has a predetermined roller, and grooves or chamfers are provided on the cam side of both arms of a swing arm on the side surface of the roller.
