Abstract:
A rotary electric machine and a gear mechanism are accommodated in a case which comprises a first accommodation chamber (1) and a second accommodation chamber (2) that are partitioned by a partition wall part (4). The gear mechanism supplies an oil to a lubrication target part by scraping up the oil in the case. An opening (5) through which the first accommodation chamber (1) and the second accommodation chamber (2) are in communication with each other is formed in the partition wall part (4). A valve element (6) is attached at the opening (5) so as to allow flow of the oil from the first accommodation chamber (1) to the second accommodation chamber (2) and restrict flow of the oil from the second accommodation chamber (2) to the first accommodation chamber (1).
