Abstract
A damper apparatus for a torque converter having a lock-up mechanism provided with a direct-coupled clutch displaceable between a joined state and a liberated state, and a torque converter body for transmitting power by a fluid, comprises a reaction ring movably fitted to an input piston of the direct-coupled clutch, a clutch plate attached to an output turbine hub on an inner diameter side of the reaction ring, and a pair of retainer plates for holding the reaction ring and the clutch plate and also sandwiching an inner peripheral spring and an outer peripheral spring therebetween. The inner and outer peripheral springs are held in corresponding windows of the retainer plates, and they are constructed and arranged to operate serially. The reaction ring and one of the retainer plates are provided with a first cooperative arrangement including a first window portion and a first projection disposed between end portions of the first window portion so as to limit relative movement of the reaction ring and the one retainer plate. The clutch plate and the other retainer plate are provided with a second cooperative arrangement including a second window portion and a second projection disposed between end portions of the second window portion so as to limit relative movement of the clutch plate and the other retainer plate.
