Abstract
An overhead valve actuation mechanism for an engine includes a cylinder head, a camshaft that is rotatably supported by the cylinder head, includes one or a plurality of valve cams, and operates opening and closing of an air intake side or air exhaust side valve via the valve cam, a rocker arm that is swung by the valve cam of the camshaft and acts on the valve to open and close the valve, and a rocker arm shaft that is supported by the cylinder head and swingably supports the rocker arm. The rocker arm shaft includes a supporting portion supporting the rocker arm and a fixed shaft portion supported by the cylinder head. The supporting portion is formed such that a rotation axis of the rocker arm parallelly and slightly separates with respect to a center axis line of the fixed shaft portion.
