ABSTRACT:
The friction device of damper disc of the invention comprises an output member, an input member, springs for coupling the two, and friction mechanisms disposed between the input member and output member. The friction mechanism comprises annular input side and output side friction members, and the input side friction member is located between the output member and the output side friction member. At the edges of the both friction members, pawls extending in the axial direction are provided, and the pawls of the input side friction member are engaged with the notches provided in the input member to coupled the input side friction member and the input member in a manner unable to rotate relatively, and the pawls of the output side friction member are engaged with the notches in the output member couple the output side friction member and output member in a manner unable to rotate relatively, and sliding friction planes are formed between the output member and input side friction member, and the output side friction member and input member, respectively.
