PROBLEM TO BE SOLVED: To provide a speed change gear for a hybrid vehicle, which allows compact configuration by reducing the entire length of a transmission housing and is reduced in parking impact.SOLUTION: A vehicular speed change gear of the invention includes: an input shaft with first and second motor/generators, a planetary gear set, first and second output gears, a brake and a rotation regulation member arranged on the axis; a hollow shaft arranged outside of the input shaft and transmitting power of an engine and the first motor/generator; and an outer shell shaft arranged outside of the hollow shaft and transmitting power of the second motor/generator. A sun gear of the planetary gear set is rotatably supported on a transmission housing by a first bearing, a ring gear is connected to the hollow shaft which is rotatably supported by a second bearing, and a planetary carrier is rotatably supported by third bearings which are arranged between the planetary carrier and the sun gear and between the planetary carrier and an extension end of the hollow shaft, respectively.SELECTED DRAWING: Figure 2

    【課題】変速機ハウジングの全長を縮小し、コンパクトな構成が可能で、パーキング衝撃を低減したハイブリッド車両用変速装置を提供する。【解決手段】本発明の車両用変速装置は、第1、第2モータ/ジェネレータ、遊星ギヤセット、第1、第2出力ギヤ、ブレーキ、及び回転制限部材が軸線上に配置された入力軸と、入力軸の外側に配置されエンジン及び第1モータ/ジェネレータの動力を伝達する中空軸と、中空軸の外側に配置され第2モータ/ジェネレータの動力を伝達する外郭軸と、を含み、遊星ギヤセットのサンギヤが第1ベアリングによって変速機ハウジングに回転可能に支持され、リングギヤが第2ベアリングによって回転可能に支持された中空軸に連結され、遊星キャリアがサンギヤとの間及び中空軸の延長端との間にそれぞれ配置された第3ベアリングによって回転可能に支持されたことを特徴とする。【選択図】図2
