摘要： A transaxle comprises a transmission differential unit including a frictional transmission mechanism and a differential mechanism. The frictional transmission mechanism includes an input shaft, a drive disc provided on the input shaft, and a driven disc whose outer peripheral edge frictionally contacts a disc surface of the drive disc.
