PROBLEM TO BE SOLVED: To provide a transmission system which has an improved damping performance with respect to torsional vibration and also can be downsized.SOLUTION: A transmission system 1 includes a hydraulic power transmission 2 having a front cover 6 for housing fluid, and a lock-up clutch 15 connecting a pump impeller 7 directly to a turbine liner 8. The transmission system 1 further includes: a first damper mechanism 21 having a first input element 21a to which engine torque is input, a first output element 21c connected to the front cover 6, and a first elastic body 21b to be expanded/contracted in the rotative direction; a second damper mechanism 22 having a second input element 22a connected to the lock-up piston 15a, a second output element 22c connected to the turbine liner 8 so as to be rotated integrally therewith, and a second elastic body 22b to be expanded/contracted in the rotative direction; and a pendulum type vibration absorber 23 provided between the first damper mechanism 21 and the second damper mechanism 22, and having a pendulum 23b oscillatably held in a rotor 23a. |
