Document Type and Number:
WIPO Patent Application WO/2015/004962
Kind Code:
A1
Abstract:
The rotor (4) of the motor (3) is arranged so as to partially overlap, in the axial direction, the outer periphery of an inner friction plate (17) and an outer friction plate (19) of the clutch (K0), and the rotor (4) is supported by a rotor support member (51) which engages a clutch drum (50) by means of splines. Multiple through-holes (42c) are formed in the clutch drum (50) in positions axially overlapping the inner friction plate (17) and the outer friction plate (19), and oil passing through the inner friction plate (17) and the outer friction plate (19) is discharged from the through-holes (42c) to the outside of the clutch drum (50). A groove portion (51f) is formed on the inner periphery of the drum unit (51b) of the rotor support member (51), wherein the portion opposite of the multiple through-holes (42c) from the end in the axial direction has a groove shape, and hereby, discharge properties are improved of the oil discharged from the through-holes (42a).
