ABSTRACT:
A worm gear type differential mechanism has a bias ratio equalization mechanism disposed between the casing and the worm gears. The bias ratio equalization mechanism includes frictional members disposed between axially opposite transverse faces of the casing and each of the worm gears, and each of the frictional materials has frictional faces which create the same friction force per unit of thrust force applied thereagainst. The frictional materials fix the worm gear axially to the casing.
