Abstract: A differential gear includes a holder which is provided between first and second pinion gears in a differential case and through which a differential pinion shaft is inserted. An insertion hole is radially formed in the differential pinion shaft. The holder is formed with a fixing hole facing the insertion hole when the differential pinion shaft is inserted through the holder. Due to insertion of a fixing pin through the fixing hole and the insertion hole, the differential pinion shaft and the holder are relatively non-rotatable. Due to the holder being held between first and second side gears, relative rotation of the holder with respect to the differential case is restricted, and the differential pinion shaft is non-rotatable relative to the differential case.
