Patent ID: 8182387

Claim:
A planetary carrier, formed of a cylindrical body, that receives a drive torque from a drive power source and differentially distributes the drive torque to a pair of output shafts, the planetary carrier comprising a gear holding portion that rotatably holds a planetary gear having two large and small gear portions whose pitch circle diameters differ from each other, wherein the gear holding portion has a first supporting surface that slidably supports tooth tip surfaces of one of the two large and small gear portions whose pitch circle diameter is larger, on all peripheral portions thereof except at one of a radially inner side and a radially outer side with respect to the carrier, and a second supporting surface that slidably supports tooth tip surfaces of the other of the two large and small gear portions whose pitch circle diameter is smaller, on all peripheral portions thereof except at the other of the radially inner side and the radially outer side with respect to the carrier.
