A starting device includes: a lock-up clutch mechanism; a fluid coupling; a spring damper including a spring, a power transfer portion transferring power from the lock-up clutch mechanism to the spring, and a power output portion transferring power from the spring to an input shaft; and a pendulum damper including a pendulum and a pendulum power transfer portion transferring power from the spring damper to the pendulum. The output portion of the lock-up clutch, the pendulum damper, the spring damper, and the fluid coupling are arranged sequentially in this order from a motor in the axial direction. The lock-up clutch mechanism output and the spring damper output are connected to each other on the outer circumferential side of the pendulum damper, and the spring damper output and the pendulum power transfer portion are connected to each other on the inner circumferential side of the pendulum.

Starting device and damper device for use therein

A fluidic torque transfer device is configured such that the attachment angle of a turbine blade at a fluid outlet of a turbine runner is smaller than the attachment angle of the turbine blade at a fluid inlet of the turbine runner. Furthermore, the turbine runner is structured so that a cross-sectional area St of a turbine flow path defined by the turbine shell, adjacent turbine blades, and the turbine core, which is perpendicular to a centerline of the turbine flow path, satisfies |St&#x2212;Sref|/Sref&#x2266;0.2, where a reference area Sref is an average of maximum and minimum values of a cross-sectional area of a pump flow path defined by the pump shell, adjacent pump blades, and the pump core of the pump impeller, which is perpendicular to a centerline of the pump flow path.

Fluidic torque transfer device

A fluidic torque transfer device configured with a pump impeller that includes a pump shell, a pump blade attached to the pump shell, and a pump core attached to the pump blade; a turbine runner that includes a turbine shell, a turbine blade attached to the turbine shell, and a turbine core attached to the turbine blade; and a stator that includes a stator blade, and rectifies a flow of a hydraulic fluid from the turbine runner to the pump impeller. The outer contour line of the turbine blade extends outward in an extending direction of a rotation center axis of the pump impeller and the turbine runner on the fluid outlet side of the turbine runner more than an outer contour line of the pump blade on the pump shell side.
