Abstract
In the valve mechanism of an internal combustion engine of the overhead camshaft type, a camshaft holder mounted on the cylinder head and supporting rocker shafts thereon has two bearing recesses having a generally semicylindrical shape, formed in a side surface remote from the cylinder head for supporting a pair of rocker shafts received therein, and a lubricating oil passage formed therein and communicating a lubricating oil passage formed in the cylinder head with the hollow interior of one of the rocker shafts. The camshaft holder is further formed therein with two communication passages communicating a peripheral groove formed in a bearing surface opening in a side surface facing the cylinder head for supporting the camshaft, respectively, with two annular gaps defined between two bolt-fitting holes and two bolts extending therethrough to fix the rocker shafts and the camshaft holder to the cylinder head. Lubricating oil supplied to the hollow interior of the above one rocker shaft through the lubricating oil passages is delivered to the hollow interior of the other rocker shaft through one of the annular gaps, one of the communication passages, the peripheral groove, the other communication passage and the other annular gap in the mentioned order.
