A driving force control device for a four-wheel drive vehicle including one pair of front or rear driven wheels which are driven directly by a prime mover and another pair of front or rear driven wheels which are driven via a hydraulic clutch, a first hydraulic pump which is driven by being operatively connected to the one pair of driven wheels, and a second hydraulic pump which is driven by being operatively connected to the other pair of driven wheels. The engagement force of the hydraulic clutch is controllable based on the difference in rotation of the first and second hydraulic pumps. The torque transmission to the other pair of the front or rear driven wheels can thus be controlled according to the driving conditions of the vehicle. The engagement force of the hydraulic clutch is controlled by an engagement force control unit by selecting from multiple engagement characteristics, in which the responsiveness of the torque transmitted by the hydraulic clutch is varied, according to the driving conditions of the vehicle.
