These camshafts are juxtaposed on a common camshaft holder supported within a cylinder head. Each of the camshafts mounts thereon at least one cam adapted to slidingly contact with a rocker arm. The apparatus is provided with a means for selectively urging said rocker arm by the selective actuation of the cams between two camshafts.
