ABSTRACT:
Ball member is provided between a ball retaining member provided integrally with a driving rotational member and opposed axial end portions of left and right drive shafts, and a selection can be made as necessary between a non-differential operation mode where the drive shafts rotate substantially equally and a differential operation mode where the drive shafts rotate differentially. The retaining member has a through-hole portion to receive part of the ball member. Shift member is slidably fitted over the retaining member and includes a ball-restricting portion of an inner diameter generally equal to an outer diameter of the retaining member and a ball-releasing portion having a greater inner diameter than the restricting portion. Power-transmitting portions are provided on the opposed axial ends with which the ball member is engageable to transmit the driving power.
