Abstract
A variable valve gear for an internal combustion engine that is capable of being disposed in a small compact manner and also capable of reducing the generation of a knocking sound. In a variable valve gear, a camshaft is supported by supporting walls of a cylinder head, and camshaft holders formed separately from the supporting walls, two exhaust rocker arms are disposed adjacent to each other, and a connecting pin is movably inserted into pin holes provided in the exhaust rocker arms by an actuator through a pushrod to connect or disconnect the exhaust rocker arms to or from each other. In the variable valve gear, the pushrod is slidably supported in a rod insertion hole of the camshaft holder with the connecting pin being disposed between the pair of camshaft holders and has an axis that is offset toward the camshaft with respect to an axis of the pushrod.
