Abstract
A valve-operating device for an engine includes a camshaft which is disposed on one side of a plane including axes of an exhaust valve and an intake valve and which has an axis substantially perpendicular to the plane. The camshaft and the exhaust and intake valves are connected to each other through a first rocker arm and a second rocker arm which are swingably carried on a rocker shaft disposed substantially perpendicular to the plane. The camshaft is formed with a large-diameter exhaust cam and a small-diameter intake cam adjoining a portion of the exhaust cam on the side of the plane. The exhaust and intake rocker arms are provided with arm portions extending in an axial direction of the camshaft to come into sliding contact with outer peripheral surfaces of the exhaust and intake cams, respectively. Thus, it is possible to open and close the exhaust and intake valves with inherent opening and closing timings, while easily avoiding interferences among components.
