Abstract
An object is to provide a fluid coupling capable of effectively utilizing an internal space of a cover member and of sufficiently exerting a performance of a device damping torsional vibration. In a fluid coupling including a cover member accommodating a fluid, a pump impeller, a turbine runner, a lockup clutch operated by a fluid pressure and selectively connecting the cover member and an output shaft, a damper mechanism having an elastic member, and a pendulum damper having a rotary member rotating integrally with the output shaft and an inertial mass capable of relative rotation with respect to the output shaft, the turbine runner, the damper mechanism, the lockup clutch, and the pendulum damper are arranged in this order in an axial direction of the output shaft inside the cover member.
