PROBLEM TO BE SOLVED: To suppress radial expansion of a snap ring while regulating movement of an oil chamber defining member for defining an oil chamber together with a piston using the snap ring.SOLUTION: A lock-up clutch 8 of a launch device 1 includes a snap ring movement regulating member 95 that regulates movement of a flange member 85 for defining an engagement-side oil chamber 86 together with a lock-up piston 80 using a snap ring 90, is supported by the flange member 85 to be positioned outside the snap ring 90, and regulates radial movement of the snap ring 90. As a result, radial expansion of the snap ring 90 can be suppressed while the movement of the flange member 85 is regulated by the snap ring 90. |
