輪駆動車の伝動装置。 A transmission comprising a main transmission mechanism having a gear train with a plurality of gears that can be selectively established, and a sub-transmission mechanism having a reduction gear train for achieving an extremely low speed lower than the lowest gear of the main transmission mechanism. , a differential device interposed between the output shaft of the transmission and one of the front and rear wheels, and a switching device for selectively transmitting the driving force of the output shaft to the other of the front and rear wheels. In the transmission device for a part-time four-wheel drive vehicle, the transmission device includes an interlock mechanism for forcibly preventing establishment of a reduction gear train of the auxiliary transmission mechanism, and the interlock mechanism and the switching mechanism includes a link mechanism such that when the switching mechanism operates to prevent transmission of driving force to the other wheel, the interlock mechanism operates to prevent establishment of the reduction gear train. A transmission device for a part-time four-wheel drive vehicle, characterized in that an actuator for operating the switching mechanism is connected in the middle of the link mechanism.
