ABSTRACT:
A junction at which the pinion shafts are connected to each other by themselves is formed in a portion of the rotational axis of an outer rotary member where the pinion shafts meet each other. Therefore, the positional relation of the pinion shafts without any substantial error is reliably secured and maintained, and the uniform transmission of power to the pinion shafts becomes possible. Accordingly, the number of parts is reduced, and it is not necessary to give any heat treatment to the clutch tooth or select any material of high strength therefor.
