A transaxle includes a planetary gear reducer and a differential device. The planetary gear reducer includes a stepped pinion, a first needle bearing, a second needle bearing, and a carrier. The stepped pinion includes a pinion shaft with which a large diameter pinion and a small diameter pinion are integrated. The first needle bearing is fitted to a part of the pinion shaft outside the large diameter pinion. The second needle bearing is fitted to a part of the pinion shaft outside the small diameter pinion. The carrier is configured to support the stepped pinion via the first needle bearing and the second needle bearing such that the stepped pinion is rotatable with respect to the carrier, and to couple the stepped pinion and the differential device.
