<p>A damper disc of the invention is equipped with a support plate (9) assembly which extends toroidally as a whole, in order to support a damper spring (8) for connecting an annular input plate (6) and an annular output plate (7) in a circumferential direction. A fixing section (15) to be fixed to the input plate (6), a connecting section (21) to be connected to the spring (8) and a supporting section (22) for supporting the outer circumference of the spring (8) are disposed on the support plate (9) assembly. A cylindrical part (30) fitted to the outer periphery of the cylindrical supporting section (22) is disposed around the outer periphery of the input plate (6) and the support plate (9) assembly is composed of a plurality of arcuate support plates (9) arranged toroidally as a whole. The fixing section (15), connecting section (21) and supporting section (22) described above are disposed on each support plate (9) and each fixing section (15) is fixed to the input plate (6) by a rivet (16). A rivet hole (32) of each fixing section (15) is one elongated in the radial direction.</p> |
