Abstract

An oil separator includes a case that has an inflow port, an outflow port, and an oil separation portion. The case has a first wall portion and a second wall portion that constitute a flow channel, and a partition wall portion that connects the first wall portion and the second wall portion. The partition wall portion partitions the flow channel into an upstream-side flow channel and a downstream-side flow channel. The oil separation portion has a constriction hole and a step portion. The step portion has a collision face located on the axis of the constriction hole and configured such that blow-by gas that passes through the constriction hole collides against the collision face, and allows oil that collects on the step portion to be discharged into the upstream-side flow channel through the constriction hole.
