An annular groove portion is integrally formed for preventing splashing of the lubricating oil by extending from a mount base (10) of the motor rotor to the motor shaft (6) to the metal bearing (5) and the radial ball bearing (20), allowing a spacer member (15) making contact with an inner ring (20a) of the radial ball bearing (20) to be attached inside the annular groove portion.
