摘要
A breather apparatus for an internal combustion engine which, when casting a cylinder head cover, can improve the fluidity of molten metal and promote gas-liquid separation through effective use of an entire breather chamber. A breather apparatus for an internal combustion engine has a cylinder head cover in which a breather chamber is formed. In the breather chamber, a number of ribs extend from a side wall included in a peripheral wall of the chamber obliquely relative to a direction in which blowby gas flows in through inflow ports. The ribs extend up to where they are continuous with respective fixing bosses. The ribs include projecting lower edge portions which are partly cut out, forming respective concave portions.
