This patent describes a transmission system for a four-wheel drive motor vehicle having a transmission disposed in a transmission case. The transmission has an output shaft rotatably supported in the transmission case, an end portion of the output shaft extends out of the transmission case and constituting an extended portion of the output shaft, and a transfer device is disposed in a transfer case for transmitting the output of the transmission to auxiliary drive wheels of the vehicle through an auxiliary drive shaft. The transfer device comprises a transfer drive gear secured to the extended portion of the output shaft of the transmission and a transfer driven gear mounted on the auxiliary drive shaft and engaged with the transfer drive gear. The improvement in the system described here is wherein the transfer case has a wall forming a hole, a bearing having an outer ring and an inner ring, the outer ring being disposed in the hole and secured to the wall of the transfer case, and the inner ring being mounted on the extended portion of the output shaft on a side of the transfer drive gear facing away from the transmission case, a nut engageable with the extended portion of the output shaft, the extended portion of the output shaft being inserted into the outer ring with the inner ring being secured to the extended portion of the output shaft by the nut engaged on the extended portion of the output shaft. This is done so that the extended portion of the output shaft is rotatably supported by the bearing at the side of the transfer drive gear facing away from the transmission case.
