ABSTRACT:
A valve drive mechanism for driving intake and exhaust valves of a vehicle engine comprises a cam shaft offset toward the intake valve, a first rocker arm driven by the cam shaft for opening and closing the intake valve and a second rocker arm driven by the cam shaft via an intermediate rocker arm for opening and closing the exhaust valve. A spark plug can be disposed in an upright posture in a cylinder head since the cam shaft is offset and does not interfere with the location of the spark plug. It is possible to design a large-valve-face valve due to the upright posture of the spark plug. Also, each rocker arm is made to be lightweight, so that desired valve movement can be expected even when the engine revolution speed is high.
