To provide a driving force distribution device capable of being miniaturized by shortening an axial length, obtaining large torque distribution with small torque of a rotating machine, and easily securing identity of operations in a case when torque distribution directions are different from each other.SOLUTION: A power distribution device 1 includes: a double pinion-type first planetary gear mechanism PG1 having a first sun gear S1, a first carrier C1, and a first ring gear R1; and a double pinion type second planetary gear mechanism PG2 having a second sun gear S2, a second carrier C2, and a second ring gear R2. The first sun gear S1 and the second carrier C2 are connected to each other and connected to a first motor 11, the first carrier C1 and the second sun gear S2 are connected to each other and connected to a second motor 12, the first and second ring gears R1, R2 are respectively connected to a right output shaft SFR and a left output shaft SFL, and a tooth number ratio between the first ring gear R1 and the first sun gear S1 and a tooth number ratio between the second ring gear R1 and the second sun gear S2 are set to the same value.SELECTED DRAWING: Figure 1

    【課題】軸線方向長さの短縮によって小型化を図り、回転機の小さなトルクで大きなトルク配分を得るとともに、トルクの配分方向が異なる場合の動作の同一性を容易に確保できる動力配分装置を提供する。【解決手段】動力配分装置1は、第1サンギヤS1、第1キャリアC1及び第1リングギヤR1を有するダブルピニオン式の第1遊星歯車機構PG1と、第2サンギヤS2、第2キャリアC2及び第2リングギヤR2を有するダブルピニオン式の第2遊星歯車機構PG2を備え、第1サンギヤS1及び第2キャリアC2は、互いに且つ第1モータ11に連結され、第1キャリアC1及び第2サンギヤS2は、互いに且つ第2モータ12に連結され、第1及び第2リングギヤR1、R2は右出力軸SFR及び左出力軸SFLにそれぞれ連結され、第1リングギヤR1と第1サンギヤS1の歯数比、第2リングギヤR1と第2サンギヤS2の歯数比は、同じ値に設定される。【選択図】図1
