Abstract
A compact fluid transmission apparatus that is able to effectively damp vibrations transmitted to an input member with a dynamic damper and a centrifugal pendulum vibration absorber. The apparatus includes a pump impeller that is connected to an input member coupled to a motor, and a turbine runner that is rotatable together with the pump impeller. The elastic body of the damper mechanism and the elastic body of the dynamic damper overlap each other with respect to an axial direction of the fluid transmission apparatus when viewed in a radial direction of the fluid transmission apparatus, and are arranged between the turbine runner and the centrifugal pendulum vibration absorber when viewed in the radial direction.
