Abstract: An engine is provided where oil is minimally blown off through a breather chamber. The breather chamber includes a plurality of breather inlet chambers each having a breather inlet which opens on a bottom wall; an oil separation chamber where blow-by gases flown out from the breather inlet chambers merge together and oil separation is performed; and a breather outlet. A ceiling wall of each breather inlet chamber is lower than a ceiling wall of an oil separation chamber. It is preferable that the respective breather inlet chambers each have: a remote-side chamber portion disposed remote from the oil separation chamber and a near-side chamber portion disposed near to the oil separation chamber. A ceiling wall of the near-side chamber portion is disposed lower than a ceiling wall of the remote-side chamber portion with a stepped portion formed between the ceiling wall and the ceiling wall.
