One end of a casing in which a rotating shaft is supported by a floating metal bush is extended to surround the outer periphery of an oil thrower formed adjacent to an end of the shaft so that an oil-thrower space is defined by the shaft, the oil thrower, the casing and the floating metal bush, and an arcuate opening is formed through the wall of the casing so that the lubricating oil trapped in the oil-thrower space is discharged through this opening to an oil outlet. |
