To provide a power transmission device that can obtain appropriate power from an electric motor during regenerative control, and can realize a smooth speed change.SOLUTION: A power transmission device 30 comprises a first speed path T1 and a third speed path T3. The first speed path T1 comprises a one-way clutch 46 for allowing power transmission from a driving shaft 3A toward a driven shaft 3B, and limiting power transmission in an opposite direction. The third speed path T3 comprises a one-way clutch 48 for allowing power transmission from the driven shaft 3B toward the driving shaft 3A, and limiting power transmission in an opposite direction. The third speed path T3 also comprises a speed change clutch member 53.SELECTED DRAWING: Figure 2B 【課題】回生制御において電動モータから適切な電力を得ることができ、且つスムーズな変速を実現できる動力伝達装置を提供する。【解決手段】動力伝達装置３０は１速経路Ｔ１と３速経路Ｔ３とを有している。１速経路Ｔ１は駆動軸３Ａから従動軸３Ｂへ向けた動力伝達を許容し、反対方向での動力伝達を制限するワンウェイクラッチ４６を有している。３速経路Ｔ３は従動軸３Ｂから駆動軸３Ａへ向けた動力伝達を許容し、反対方向への動力伝達を制限するワンウェイクラッチ４８を有している。３速経路Ｔ３は、さらに変速クラッチ部材５３を有している。【選択図】図２Ｂ
