Abstract
A four wheel drive vehicle comprising dirigible front wheels supported by an front axle case, a propelling drive transmission disposed in a rear portion of the vehicle, rear wheels receiving a drive from the propelling drive transmission, and a front wheel drive transmission mounted in the front axle case and receiving a drive divided out from the propelling drie transmission. The front wheel drive transmission is switchable between a standard drive mode in which an average peripheral speed of the front wheels is substantially the same as an average peripheral speed of the rear wheels, and an accelerating mode in which the average peripheral speed of the front wheels is greater than the average peripheral speed of the rear wheels. The front axle case is supported by the vehicle to be pivotable on a pivotal axis disposed at a mid-position transversely of the vehicle and extending longitudinally of the vehicle.
