Abstract
An internal combustion engine includes: an engine main body demarcating a breather chamber that is partitioned from a crank chamber, disposed above the crank chamber, and has an inlet opening opened toward the crank chamber; a multistage transmission housed in the crank chamber and having speed change gear trains that are respectively supported by a pair of transmission shafts and mesh with each other; and a breather passage disposed above the transmission shafts and extending in an up-down direction from the crank chamber to the inlet opening of the breather chamber, the inlet opening being disposed above a half in a height direction of the breather chamber. Accordingly, the internal combustion engine can suppress the entry of splashed oil into the breather chamber more than ever before.
