To realize a torque vectoring device capable of suppressing enlargement of a device as a whole.SOLUTION: A torque vectoring device includes a pinion gear unit (34) in which a first pinion gear (36) engaged with an input gear (15), a second pinion gear (37) engaged with a first output gear (22), and a third pinion gear (38) engaged with a second output gear (27) are integrated. The number of teeth of the first output gear (22) and the number of teeth of the second output gear (27) are same as each other. The number of teeth of the input gear (15) is even number, and different from the numbers of teeth of the first output gear (22) and the second output gear (27). The numbers of teeth of the first pinion gear (36), the second pinion gear (37) and the third pinion gear (38) are smaller than an integer of a speed reduction ratio.SELECTED DRAWING: Figure 4 【課題】装置全体の大型化を抑制できるトルクベクタリング装置を実現する。【解決手段】トルクベクタリング装置は、入力ギヤ（１５）に噛み合う第１ピニオンギヤ（３６）と第１出力ギヤ（２２）に噛み合う第２ピニオンギヤ（３７）と第２出力ギヤ（２７）に噛み合う第３ピニオンギヤ（３８）とが一体化されたピニオンギヤユニット（３４）を備える。第１出力ギヤ（２２）の歯数と第２出力ギヤ（２７）の歯数とが同一である。入力ギヤ（１５）の歯数が、偶数であって、第１出力ギヤ（２２）及び第２出力ギヤ（２７）の歯数と異なる。第１ピニオンギヤ（３６）、第２ピニオンギヤ（３７）、及び第３ピニオンギヤ（３８）の歯数が、整数の減速比よりも小さい。【選択図】図４
