A vehicular differential device includes a differential rotation mechanism, and a torque input member that receives drive torque, the drive torque is distributed and transmitted to a first drive shaft and a second drive shaft. The differential rotation mechanism includes an input gear that rotates as a unit with the torque input member, an output gear that rotates as a unit with the first drive shaft, a first gear and a second gear that rotate as a unit, and a carrier that supports the first gear and the second gear, the carrier being configured to rotate as a unit with the second drive shaft. The gear ratio between the input gear and the first gear is different from that between the output gear and the second gear. During differential rotation, the first drive shaft and the second drive shaft are rotated in opposite directions.
