A control device for a torque distributor provided with a control means acquiring a demand value of a torque distributed to second driving wheels (W3, W4) using a torque distributor (10) and outputs a command value (TR) of torque corresponding to the demand value of torque. When a variation per unit time (ND) of a differential rotation speed (NS) between a drive source (3) side and a second driving wheel side with respect to the torque distributor in a torque transmission path (20) is a predetermined first threshold (ND1) or more, the control means (60) performs a torque command value limit control controlling the torque command value to a predetermined limit value (TR1) or less. This can secure the running stability necessary for the vehicle by distributing an appropriate torque to the second driving wheels using the torque distributor, while enabling proper protection of components including the torque distributor.
