Beschreibung
Zusammenfassung:	A breather device comprises a breather chamber ( 22 ) provided in a valve arm chamber ( 2 ) arranged above a cylinder head of an engine. In the breather chamber, blow-by gas including oil mist is separated into oil component and gas component, and the oil mist is removed from the blow-by gas. The interior of the breather chamber is alternately divided into plural horizontally juxtaposed rooms ( 22 a , 22 b , 22 c) by a partition ( 23 ) extended from a bottom surface of the breather chamber and a partition ( 2 a) extended from a ceiling surface of the breather chamber. Plural oil trap members ( 10 ) for trapping oil mist in the blow-by gas are arranged in the breather chamber. Especially, the oil trap member arranged at a blow-by gas inlet of the breather chamber is held by a holder ( 11 ) made separately from members ( 2, 7 ) forming the valve arm chamber ( 5 ).
