Abstract: A fluid coupling includes a cover, an impeller, a turbine, an output hub, a lock-up piston, and a wall member. The impeller is fixed to the cover. The turbine is disposed opposite to the impeller. The output hub outputs a torque transmitted thereto from the turbine. The lock-up piston is disposed between the cover and the turbine. The lock-up piston is disposed to be axially slidable on the output hub. The lock-up piston is configured to be engaged by friction with the cover. The wall member is attached to the output hub. The wall member defines a hydraulic chamber in cooperation with the lock-up piston.

Abstract: A stator according to the present invention includes a stator hub, a large number of blades radially provided in a projecting manner at regular intervals on an outer periphery of the stator hub, and a stator core formed so as to surround outer ends of the respective blades. The stator is integrated by separately molding a front side stator member and a rear side stator member as two axially split members, respectively, and then joining the front side stator member and the rear side stator member.
