。[Claims for Utility Model Registration] Two types of cams with different shapes are provided for at least one of the intake valve and the exhaust valve, and a rocker arm is disposed between each of these cams and the valve via a rocker shaft, and In an engine equipped with a linkage switching mechanism that selectively links the above-mentioned valves to these cams and switches the linkage according to the operating condition, a leaf spring is attached to a high-speed rocker arm that is freely rotatably fitted to the rocker shaft on one side. By fixing the base end of the high-speed rocker arm to the other rocker shaft while the leaf spring is elastically deformed, the high-speed rocker arm is attached to the high-speed cam by the elastic restoring force of the leaf spring. A valve train for an engine, characterized in that it is biased to follow the motion.
