Abstract
In a fluid coupling wherein a turbine shell is welded to a turbine hub, it is necessary to take care of the strength of the welded portion because the turbine shell is displaced toward the pump blade as the torque thereof is transmitted. A fluid coupling () according to the present invention is provided with an input-side rotary constituent (A) including a pump blade (), to which is attached an input member, and an output-side rotary constituent (B) including a turbine shell (), to which is attached a turbine blade () opposed to the pump blade (), and a turbine hub, to which is coupled an output member (), the turbine hub () being welded to an inner peripheral portion of the turbine shell (), wherein the turbine shell () and the turbine hub () have contact surfaces (), respectively, extending along a rotational axis () of the fluid coupling (), and a joint portion () is formed by the welding on the contact surfaces () closer to the pump blade ().
