摘要
A ceiling surface of a rocker cover mounted on a top of a cylinder head has an oil guide groove and an oil dripping portion. The oil guide groove extends along a rotation direction of a chain and faces the chain for guiding lubricating oil droplets separated from the chain into a single flow in a certain direction. The oil dripping portion is continuous with the oil guide groove and protruding toward a valve-operating device for dripping the lubricating oil guided by the oil guide groove onto the valve-operating device. Oil droplets thrown off from the chain are collected by the oil guide groove and dripped onto the valve-operating device via the oil dripping portion. Therefore, it can effectively supply the oil to a position where the valve-operating cam slidably contacts with the slipper, thereby improving the frictional resistance of the valve-operating device.
