The present invention provides a torque vectoring device capable of downsizing a brake device for applying a braking force to a drive wheel. The torque vectoring device comprises: a drive motor (2); a differential unit (4) including a first planetary gear unit (10) that transmits torque to a drive wheel (3a) at one side from the drive motor (2), and a second planetary gear unit (11) that transmits torque to a drive wheel (3b) at the other side from the drive motor (2); a differential motor that transmits torque to any one of reaction elements (17) of the differential unit (4); a reversing mechanism that transmits torque between the reaction elements while reversing; a rotary shaft (9) connecting input elements (12, 16) of the planetary gear units (10, 11); a rotary member (8) that transmits torque of an output shaft (6) of the drive motor (2) to the differential unit; and a brake device (B) that is adapted to apply the braking force to the rotary member (8).
