Breather chamber structure for internal combustion engine

Abstract

Provided is a breather chamber structure for an internal combustion engine that is capable of increasing a passage length inside a breather chamber with a simple structure. A breather chamber structure for an internal combustion engine that is applicable to a breather chamber for temporarily storing, inside an internal combustion engine, blowby gas generated during operation of the internal combustion engine and to be recirculated to an intake passage, includes, in the breather chamber, a two-stage section formed by a first plate and a second plate that are attached to a rear surface side of a cylinder head cover attached to a cylinder head of the internal combustion engine and that are parallel with and spaced apart from each other, the two-stage section, and including a first chamber and a second chamber that are partitioned by the first plate.

Dependencies are inferred from the claim text.
