ABSTRACT:
A structure for radially positioning a friction member in a damper disc comprises an output hub including a radial flange; a pair of side plates rotatably disposed at opposite sides of the flange; a torsion spring mechanism operable to circumferentially connect the side plates to the flange; and a friction mechanism rotatable fitted around the hub and associated to the side plate for generating a friction force in accordance with relative torsion between the side plates and the flange; the friction mechanism including an annular friction member, of which outer periphery is radially held and guided concentrically to a center of the disc by circumferentially spaced projections formed on the adjacent side plate.
