ABSTRACT:
A fixation structure for a valve system rotation shaft of an internal combustion engine to support a camshaft with a cylinder head through the use of a lower cam holder and cam caps, which are formed separately from the cylinder head. The fixation structure eliminates the necessity of taking special vibration
oise control measures for a head cover thus preventing an increase in the cost, size, and weight of the head cover. A head external wall extends toward the head cover rather than toward a head middle surface in such a manner so as to cover the circumference of the lower cam holder fixed to a head middle surface. The connection to the holder fixation section is established with the base end of an external wall of the head cover abutted on the leading end of the head external wall.
