FLUID TRANSMISSION DEVICE

摘要

The purpose of the present invention is to provide a fluid transmission device capable of effectively utilizing the space inside a cover member while also manifesting adequate performance as a device for attenuating twisting vibrations. A fluid transmission device provided with: a cover member for holding a fluid; a pump impeller; a turbine runner; a lock-up clutch, which is operated by fluid pressure and is for selectively connecting the cover member with the output shaft; a damper mechanism having an elastic member; and a pendulum vibration damper having a rotating member that rotates integrally with the output shaft and an inertial mass capable of rotating relative to the output shaft. In the fluid transmission device, the turbine runner, damper mechanism, lock-up clutch and pendulum vibration damper are disposed inside the cover member in said order in the axial direction of the output shaft.
