PROBLEM TO BE SOLVED: To provide a right and left wheel driving device which can obtain a relatively large amplification factor of torque difference and simplify the device configuration to reduce the cost.SOLUTION: A right and left wheel driving device 1 comprises a gear device 5 which is interposed between two driving sources 2, 3 and right and left drive wheels 4R, 4L and is formed by combining two planetary gear mechanisms 10A, 10B having three elements and two degrees of freedom on the same shaft. Both planetary gear mechanisms 10A, 10B include sun gears S1, S2, second rotors R1, R2 and third rotors C1, C2. The gear device 5 has a first combined element 11 in which one S1 of the sun gears and the other C2 of the third rotors are combined, and a second combined element 12 in which one third rotor C1 and the other sun gear S2 are combined. The two driving sources 2, 3 are connected to the first combined element 11 and the second combined element 12, respectively, and the right and left drive wheels 4R, 4L are connected to the second rotors R2, R1, respectively. 【課題】比較的大きなトルク差増幅率を得つつ、装置構成を簡素化してコストを低減することができるようにした、左右輪駆動装置を提供する。【解決手段】二つの駆動源２，３と左右の駆動輪４Ｌ，４Ｒとの間に介設され、３要素２自由度の遊星歯車機構１０Ａ，１０Ｂを同軸上に二つ組み合わせてなる歯車装置５を備えた左右輪駆動装置１である。遊星歯車機構１０Ａ，１０Ｂは、何れもサンギヤＳ１，Ｓ２と第二回転体Ｒ１，Ｒ２と第三回転体Ｃ１，Ｃ２とを含む。歯車装置５は、一方のサンギヤＳ１と他方の第三回転体Ｃ２とが結合された第一結合要素１１と、一方の第三回転体Ｃ２と他方のサンギヤＳ２とが結合された第二結合要素１２とを有する。二つの駆動源２，３はそれぞれ第一結合要素１１，第二結合要素１２に接続され、左右の駆動輪４Ｌ，４Ｒはそれぞれ第二回転体Ｒ１，Ｒ２に接続される。【選択図】図１
