Abstract
An internal combustion engine with a breather apparatus, has: a cylinder head cover having a top wall and a circumferential wall which define an internal upper space within the cylinder head cover; and a bottom plate closing an opening at a lower end of the circumferential wall of the cylinder head cover to form a gas-liquid separation chamber. The bottom plate is inclined when the engine is set in a normal posture. A recessed portion for holding oil and serving as an oil return port is formed in a lowest portion along an edge portion of a lower side of a circumferential edge portion of the inclined bottom plate in such a manner as to straddle the circumferential wall from below. Thus, a lower end portion of the circumferential wall is brought into contact with oil held in the recessed portion to thereby close the oil return port airtightly.
