Abstract
The disclosure prevents oil separated from blow-by gas by using a breather chamber and discharged to a valve chamber from leaking to the outside from a breather chamber mounting surface between the breather chamber and the valve chamber. A breather chamber includes cylindrical drain passages communicating with a valve chamber, and tips of the drain passages exceed breather chamber mounting surfaces of a cylinder head and a head cover and protrude from opening parts toward a side of the valve chamber, so the oil separated from the blow-by gas in the breather chamber can be reliably discharged to the valve chamber and prevented from leaking to the outside from the breather chamber mounting surfaces.
