Abstract
[Technical problem] To provide a power transmission mechanism for a four-wheel drive vehicle in which a prime mover is disposed at a low position to lower the center of gravity of the vehicle while a driving path from a transmission to a front wheel differential mechanism is also shortened. [Solutions] In a power transmission mechanism for a four-wheel drive vehicle, the power of a prime mover is transmitted to a front wheel differential mechanism which is disposed in front of the prime mover, and to a rear wheel differential mechanism which is disposed behind a transmission, through the transmission which is disposed behind the prime mover. The transmission comprises a front and rear wheel drive shaft that extends along the longitudinal direction of the vehicle body. The transmission is arranged separately from the prime mover and a rear axle drive device. The rear end portion of the front and rear wheel drive shaft is connected to an input shaft of the rear wheel differential mechanism. The front end portion of the front and rear wheel drive shaft is connected to an input shaft of the front wheel differential mechanism via a front wheel power transmission shaft that extends along the longitudinal direction of the vehicle body and passes through the space beneath the prime mover. The front wheel differential mechanism, the prime mover, the transmission, and the rear wheel differential mechanism are arranged along the longitudinal direction of the vehicle body at the center of the vehicle width of the vehicle.
