Abstract

In a damper device in a lock-up clutch for a torque converter device, a projection is integrally formed at either the driving or driven plates and an arc-shaped expanded part is integrally formed at the other of the driving and driven plates. The arc-shaped expanded part is provided with a concave portion which has a circumferential end. The integral projection is fitted in the concave portion in such a manner that the maximum relative rotation between the driving and driven plates is attained when the integral projection is engaged with the circumferential end of the concave portion.
