PROBLEM TO BE SOLVED: To incorporate a differential lock switching means by compact design, without complicating a driving force transmission system of a four-wheel drive vehicle provided with a driving switching means. SOLUTION: A low clutch 17 and a dog clutch 19 are arranged in two stages on the inside and outside in the radial direction on one side of a front side differential device 9 being undriven in two-wheel drive. The low clutch 17 is formed as a driving switching means for engaging and disengaging the transmission of rotation to an axle shaft 11b from a side gear 16b, and the dog clutch 19 is formed as the differential lock switching means for joining the side gear 16b to a differential case 14, and the driving switching means and the differential lock switching means are arranged in proximity of one side of the differential device 9. The differential lock switching means can be incorporated by the compact design without complicating the driving force transmission system of the four-wheel drive vehicle provided with the driving switching means.
