Provided is a torque control device for a four-wheel-drive vehicle that can stably output a minimum torque required to start or drive the vehicle to the auxiliary wheel side under a road surface condition that main driving wheels are stuck in the idling state or under a road surface condition equivalent thereto. When front wheels Wf1, Wf2 are judged to be stuck in the idling state, a current rear torque TrCMD is raised step by step. And, when a brake operates in the state in which the four wheels are at stop after raising the command torque TrCMD step by step, the command rear torque TrCMD is released. And, the command rear torque TrCMD is raised step by step when the command rear torque TrCMD continues to be released for a second threshold time.
