PROBLEM TO BE SOLVED: To provide a compact power transmission system for hybrid vehicle, capable of attaining size reduction and high maintainability by disposing an actuator mechanism for activating a driving force interrupting/coupling mechanism with good space efficiency. SOLUTION: This power transmission system for hybrid vehicle, capable of being activated by an engine and an electric motor, includes: an engine; an electric motor; a deceleration mechanism comprising a plurality of gear assembly for decelerating the driving force of the electric motor; a differential system for distributing decelerated driving force by the deceleration mechanism and engine driving force to both left and right driving wheels; and a driving force interrupting/coupling mechanism mounted onto the deceleration mechanism. With this constitution, the actuator mechanism which activates the driving force interrupting/coupling mechanism is positioned between the electric motor and the differential system, so as to be aligned with the electric motor in the axial direction thereof.
