CYLINDER HEAD FOR INTERNAL COMBUSTION ENGINE

摘要

Easy machining makes it possible to effectively supply engine oil to a valve opening/closing mechanism. A cylinder head (7) is provided with: a valve opening/closing mechanism (8) for opening and closing an intake valve (71) and an exhaust valve (72) by means of a camshaft (82); and a main body part (73) for supporting the valve opening/closing mechanism, the intake valve, and the exhaust valve from the interior thereof, the main body part forming a combustion chamber (63). The cylinder head (7) further includes a guide plate for supplying engine oil from above the valve opening/closing mechanism. The guide plate is provided with a groove part (108) formed by bending part of the guide plate, the groove part being arranged in a position of overlapping the valve opening/closing mechanism as seen in a plan view of the engine (5).
