A lockup damper of a torque converter 1 includes a retaining plate 14, a driven member 10, first coil springs 13A, second coil springs 13B and an intermediate plate 30. The first coil springs 13A are disposed between the retaining plate 14 and the driven plate 10. The second coil springs 13B are dis
A lockup damper of a torque converter 1 includes a retaining plate 14, a driven member 10, first coil springs 13A, second coil springs 13B and an intermediate plate 30. The first coil springs 13A are disposed between the retaining plate 14 and the driven plate 10. The second coil springs 13B are disposed between the retaining plate 14 and the first coil springs 13A. The intermediate plate 30 has spring support portions 32 disposed between the first and second coil springs 13A and 13B for circumferentially supporting the first and second coil springs 13A and 13B, and engagement portions 33a, 33b, 34a and 34b engageable with the retaining plate 14 or the driven member 10.
