ABSTRACT:
A clutch plate (4) and a retaining plate (5) are disposed to face each other. A separate flange (3) is interposed between the two plates and has cutaways (3d) extending in the circumferential direction at its outer circumferential edge. Large coil springs (7) couple the two plates and the separate flange (3) with each other in the circumferential direction. A plate coupler (30) includes a sleeve portion (31) and fastener portions (32) for coupling outer circumferential portions of the two plates with each other, and projections (33) extending radially inwardly from the sleeve portion (31) and contactable with both ends in the circumferential direction of the cutaways 3d of the separate flange (3) to overcome the problems associated with conventional stop pins and to increase a relative twist angle between an input member and an output member.
