A rear axle for a four-wheel drive vehicle comprises: a ring gear portion that rotates around an axis parallel to the width direction of the four-wheel drive vehicle, and a differential gear case that rotates around the axis together with the ring gear portion; a differential gear portion installed inside the differential gear case; a main shaft extending along the axis while penetrating the differential gear portion; a first auxiliary shaft that rotates together with the differential gear case when it rotates; a second auxiliary shaft that is freely rotatable about the main shaft around the axis and is connected to one side of the main shaft; a reduction gear that outputs a rotation speed reduced from the rotation speed of the differential gear case; and a first clutch that connects the first auxiliary shaft and the second auxiliary shaft in a first four-wheel drive mode so as to be able to transmit power, and connects the reduction gear and the main shaft and the second auxiliary shaft in a second four-wheel drive mode so as to be able to transmit power.
