Abstract
A lower partition wall having a through hole vertically penetrates the lower partition wall center. A spindle is inserted into the through hole. The top surface side of the lower partition wall includes a convex portion, a groove, and a drain hole. The convex portion is concentrically disposed at the through hole periphery. The groove extends, from an outer peripheral side of the convex portion, toward the through hole on an inner peripheral side. The drain hole is outside the convex portion, vertically penetrating the lower partition wall. The separated oil circles a top surface of the lower partition wall. The oil flowing to an inner peripheral side of the lower partition wall is guided to the groove and flows into the through hole. The oil flowing to an outer peripheral side of the lower partition wall flows into the drain hole.
