<P>PROBLEM TO BE SOLVED: To provide a lubricating device for a dynamic valve system capable of exhibiting efficient lubricating performance with a small oil feeding amount. Ž<P>SOLUTION: The lubricating device of the dynamic valve system includes a camshaft having a cam follower for lifting valve elements installed in a plurality of cylinders of an internal combustion engine, an oil passage formed inside the camshaft in such a way of being stretched in the axial direction, an oil outflow hole penetrating a clearance between the peripheral surface of a cam lobe and the oil passage, and an intermittently feeding device to feed oil intermittently to the oil passage accompanied by the rotation of the camshaft. The intermittently feeding device allows the oil to flow into the oil passage when the oil outflow hole confronts the follower link of the cam lobe. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
