Abstract
An oil mist separator includes a case, an oil collecting portion, and a gradual change portion. The case includes a case main body, an inlet for blow-by gas provided on an upstream side of the case main body in a flowing direction of the blow-by gas, and an outlet for blow-by gas provided on a downstream side in the flowing direction of the case main body. The oil collecting portion is accommodated in the case main body. The gradual change portion is provided in the case and is located in at least one of a space between the inlet and the oil collecting portion in the flowing direction and a space between the oil collecting portion and the outlet in the flowing direction. A cross-sectional flow area of the gradual change portion is gradually decreased as a distance from the oil collecting portion in the flowing direction increases.
