A power transmission system having a pendulum damper is provided. A rolling member of the pendulum damper is arrange in a rotary member, and a vibration damping performance of the pendulum damper is enhanced by increasing an inertia moment of the rolling member to be larger than that of the rotary member. The power transmission system is comprised of a hydraulic route for transmitting power between an input member and an output member through a fluid coupling, a mechanical route for transmitting power between the input member and the output member by engaging a lockup clutch, a pendulum damper that damps torsional vibrations of the output member by an oscillating motion caused by the torsional vibrations, and an elastic damper that damps the torsional vibrations by a relative rotation between a drive member and a driven member connected through an elastic member. The pendulum damper is disposed on the mechanical route, and one of the lockup clutch and the elastic damper is disposed on an output side of the pendulum damper. |
