Abstract
An oil separator includes a separation chamber for separating oil mist from blow-by gas of an internal combustion engine and a case in which the separation chamber is formed. The oil separator further includes an introduction pipe, which is connected to the case and introduces blow-by gas into the separation chamber, and a discharge pipe, which is connected to the case and discharges blow-by gas that has passed through the separation chamber. An inlet inner wall portion, which is formed by a part of the discharge pipe that includes the inlet, protrudes further downward than an outlet inner wall portion, which is formed by a part of the discharge pipe that includes the outlet. A step is formed at the boundary between the inlet inner wall portion and the outlet inner wall portion to prevent oil from moving along the inner wall of the discharge pipe toward the outlet.
