摘要： A differential includes a pinion shaft holder, a differential case, a first side gear, a second side gear, a first spring and a second spring. The differential case includes a first side boss portion and a second side boss portion. The first spring is interposed between the first side boss portion and the first side gear. The second spring is interposed between the second side boss portion and the second side gear. A recessed portion is provided on the pinion shaft holder and is configured to avoid interference with an auxiliary tool. The auxiliary tool maintains one of the first spring and the second spring in the compressed state.

摘要： Providing an electric vehicle transaxle suppressing occurrence of wear, seizure, etc. of a one-way clutch as compared to a conventional one. When an electric motor MG is driven and a one-way clutch 34 moves in a rotation axis C1 direction, the one-way clutch 34 comes into contact with a flange portion 46b of an inner race 46 or a supporting portion 30b of a transaxle housing 30 via a sliding washer 74 and, therefore, direct contact is prevented between the one-way clutch 34 and the flange portion 46b of the inner race 46 or the supporting portion 30b and wear, seizure, etc. of the one-way clutch 34 are suppressed.
