ができる効果を有する。 In this way, according to the present invention, one combustion chamber 1
The head cover 9 is equipped with a valve operating mechanism including a rocker arm 13 that interlocks with a plurality of intake valves 2a and exhaust valves 2b provided in the cylinder head 3, and a tachometer gear 6 that meshes with a drive gear 5 formed on a camshaft 4 in the cylinder head 3 is attached to the cylinder head. In the tachometer gear mounting device for the engine head provided in the head 3, the transmission shaft 7 of the tachometer gear 6 is provided in a space surrounded by a pair of rocker arm shafts 8, 8 parallel to the camshaft 4 and the rocker arm 13. Because of this, even in a head cover equipped with a complicated valve mechanism, the tachometer gear can be mounted without being blocked by the valve mechanism.
