DAMPER MECHANISM

摘要

A damper mechanism (4) comprises a clutch plate (21) and a retaining plate (22) juxtaposed in the axial direction, a hub flange (6) disposed between the both plates (21, 22) in the axial direction so as to be capable of rotating relative to each other, and a second coiled spring (8) for elastically connecting the both plates (21, 22) to the hub flange (6) in the rotating direction. The both plates (21, 22) include a pair of first body parts (28), and connection parts (31) which are disposed between a first projection part (49) and a second projection part (57) in their rotation direction and which connect the pair of first body parts (28) to each other. The connection parts (31) are so disposed that their pitches adjacent to each other are different from each other.
