Abstract
Providing a drive transmission apparatus for vehicle capable of ensuring the adaptability of an electric motor to a high-temperature environment and increasing the degree of freedom for apparatus layout. The drive transmission apparatus for vehicle serves to distribute a drive force generated by a rotary drive source 2 between drive wheels 6, 12, and includes: an input member 7 applied with the drive force from the rotary drive source 2; an output member 9 for outputting the drive force to the drive wheels 12; a hydraulic clutch 21 for hydraulically performing drive transmission/transmission cut-off between the input member 7 and the output member 9; an oil pump 31 for applying a hydraulic pressure to the hydraulic clutch 21; and a sensorless brushless motor for driving the oil pump.
