A drive transmission apparatus for distribution of drive force

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.
