PROBLEM TO BE SOLVED: To reduce the noise of a driving force transmission gear, and to inhibit the temperature rise of a lubricating oil for not giving the influence to the durability of an operating device. SOLUTION: In this device, a transfer 44 is connected with an engine 40 mounted on a front part of a vehicle, through a main transmission 42, and a propeller shaft 52 is connected between the transfer and a rear differential device 54 in a fore and aft direction of the vehicle. An input gear 52a formed on one edge of the propeller shaft, is engaged with a rear wheel output gear 44a at the transfer side, for transmitting the driving torque of an engine to a rear wheel side, and an output gear 52b formed on the other edge of the propeller shaft, is engaged with a rear differential gear 54a of the rear differential device. The input gear 52a and the output gear 52b have the numbers of tooth different from each other. |
