To provide a power transmission mechanism that facilitates supporting a vehicle in which one or more prime movers are not connected to a single drive shaft, and that not inhibit degree of freedom for layout of a vehicle compactly because it does need to use a large number of mechanical elements for speed reduction.SOLUTION: A power transmission mechanism 1 comprises: a ring gear 3 of an internal gear connected to an output shaft 2; a plurality of sets of gear trains 5 and 6 disposed inside the ring gear 3 and having different gear ratios for transmitting torque from an input shaft 4 to the ring gear 3; and a path switching device 7 that switches the path for transmitting torque from the input shaft 4 to the ring gear 3 by selecting one of the plurality of sets of gear trains 5 and 6.SELECTED DRAWING: Figure 1 【課題】一つの駆動軸に対し原動機が一つ以上接続しない車両へ対応することが容易であり、また、減速のための多数の機械要素を使用する必要がなく、コンパクトで車両のレイアウト自由度を阻害しない動力伝達機構を提供する。【解決手段】動力伝達機構１は、出力軸２に繋がる内歯のリングギヤ３と、リングギヤ３の内部に配設され、該リングギヤ３に入力軸４からのトルクを伝達するギヤ比の異なる複数組のギヤ列５，６と、複数組のギヤ列５，６のいずれかを選択することにより、入力軸４からリングギヤ３へトルクを伝える経路を切り替える経路切替装置７とを備える。【選択図】図１
