A centrifugal oil filter in which a cylindrical housing 42 is rotatable by the reaction force from oil jets 56 leaving via nozzles 44, is increased by the provision of ribs 54 on the inner wall surface of the cylindrical housing 28. This enables the cylindrical vessel 42 to be provided with an internal coarse oil filter while allowing an increase in acceleration and rotational speed.
