Abstract
A breather device includes: a breather chamber into which oil mist in a crank chamber of a combustion engine is introduced; and a breather passage configured to guide oil mist from a crank chamber into the breather chamber. The breather chamber has formed therein a labyrinth structure in which gas-liquid separation of the oil mist is performed. An introduction pipe forming a part of the breather passage is communicated with an upper portion of the crank chamber, and projects upward from an upper end portion of the crank case.
