To provide a compact hydraulic power transmission which can more effectively damp vibration transmitted to an input member by a dynamic damper and a centrifugal pendulum vibration absorber device.
The hydraulic power transmission 1 includes: the dynamic damper 10 for damping vibration transmitted to a front cover 3, and the centrifugal pendulum vibration absorber device 20. In the hydraulic power transmission 1, a first and second coil springs 81, 82 of the damper mechanism 8 and a coil spring 100 of the dynamic damper 10 overlap in an axial direction of the hydraulic power transmission 1 when viewed from a radial direction of the hydraulic power transmission 1, and are arranged between a turbine runner 5 and the centrifugal pendulum vibration absorber device 20 when viewed from the radial direction.
