PROBLEM TO BE SOLVED: To suppress the generation of gear noise newly when engaged in a planetary gear mechanism that has a rotary element fixed to be selectively un-rotatable by an engagement mechanism.SOLUTION: A planetary gear mechanism incorporated in a hybrid vehicle Ve includes: a first planetary gear mechanism for constituting a power division mechanism 10 that divides power output from an engine 1 into a first motor MG 1 side and a drive wheel 2 side; and a second planetary gear mechanism for constituting a speed change part 20 functioning as a speed booster by fixing a second ring gear R2 un-rotatable, the ring gear functioning as a counteractive element by a selectable one-way clutch 30 being an engagement mechanism. Further, the number of gears of a first sun gear S1 of the power division mechanism 10 and the number of gears of a second sun gear S2 of the speed change part 20 are the same.SELECTED DRAWING: Figure 1

    【課題】係合機構によって選択的に回転不能に固定される回転要素を有する遊星歯車機構において、係合時に新たなギヤノイズが発生することを抑制すること。【解決手段】ハイブリッド車両Veに搭載される遊星歯車機構において、エンジン1が出力した動力を第1モータMG1側と駆動輪2側とに分割する動力分割機構10を構成する第1遊星歯車機構と、係合機構であるセレクタブルワンウェイクラッチ30によって反力要素となる第2リングギヤR2を回転不能に固定することで増速機として機能する変速部20を構成する第2遊星歯車機構とを備え、動力分割機構10の第1サンギヤS1の歯数と、変速部20の第2サンギヤS2の歯数とが同一であることを特徴とする。【選択図】図1
