Abstract

PURPOSE:To obtain thorough lubrication to every sliding part by providing a lubricating oil reservoir which covers from the underside the rotating locus of a cam nose. CONSTITUTION:A lubricating oil reservoir 31, which covers from the underside both a projected end of an inlet lifer 18 to a valve closing cam chamber 15 and the lower part of a rotating locus 30 of each cam nose 21a of an inlet cam shaft 21, is provided. The lubricating oil reservoir 31 is such that scattered lubricating oil 28' is accumulated therein, and the lubricating oil 28' is calculating, giving each sliding part an oil bath. In this case, the lubricating oil reservoir 31 is situated sufficiently near both projected end of the inlet filter 18 and rotating locus of the cam nose 21a. In other words, it prevents the amount of the lubricating oil 28' within the lubricating oil reservoir 31 from uselessly increasing. Accordingly, each sliding part can fully be lubricated, keeping the amount of supply of the lubricating oil to the sliding part low.
