PROBLEM TO BE SOLVED: To provide a fluid coupling, facilitating fitting of a bearing disposed between an impeller hub and a turbine hub. SOLUTION: An impeller 3 is a member constituting a fluid chamber, and has an impeller blade 17 and an annular impeller hub 18 provided on the inner periphery side of the impeller blade 17. A turbine 4 is disposed opposite to the impeller 3 in the fluid chamber, and has a turbine blade 22 and an annular turbine hub 23 provided on the inner periphery side of the turbine blade 22. A ball bearing 8 is disposed between the inner peripheral surface of the impeller hub 17 and the outer peripheral surface of the turbine hub 23. A first stop ring 34 engaged with a first groove 19 and an engagement groove 31a is fixed by making the ball bearing 8 and the impeller hub 18 approach each other in the axial direction. A second stop ring 35 engaged with a second groove 24a fixes the ball bearing 8 and the turbine hub 23. COPYRIGHT: (C)2005,JPO&NCIPI |
