Abstract
Herein disclosed is a fluid coupling which comprises: a pump impeller connected to the output shaft of an engine; and a turbine runner for transferring a working fluid to and from the pump impeller. On the pump impeller and the turbine runner, respectively, there are arranged a pump blade and a turbine blade without any inner core for guiding the flow of the working fluid inside of the pump impeller and the turbine runner. By bending at least one of the working fluid outlet side of the pump blade and the working fluid inlet side of the turbine blade, there is formed transfer limit means for limiting the transfer of the working fluid when the fluid coupling is in a stalling state.
