PROBLEM TO BE SOLVED: To provide a fluid coupling having nearly flat input capacity coefficient property in a low speed ratio region without increasing the size of its outer diameter. SOLUTION: The fluid coupling comprises an impeller 3, a turbine 4, a bearing 8, and a baffle 35. The impeller has an impeller shell 16, an impeller blade 17, and an impeller hub 18. The turbine is arranged opposite to the impeller in a fluid chamber, and it has a turbine shell 21 constituting a torus together with the impeller shell, a turbine blade 22, and a turbine hub 23. The bearing rotatably supports the impeller hub relative to the turbine hub. The baffle is provided in the torus for preventing part of the flow of operating fluid in the torus. The impeller blade and the turbine blade have chamfered portions 17a, 22a formed at their front ends, respectively. COPYRIGHT: (C)2005,JPO&NCIPI
