Patent ID: 7207889

Claim:
A damper mechanism for transmitting a torque while absorbing and damping torsional vibrations, comprising: a first rotary member; a second rotary member being rotatable relatively to said first rotary member; a first elastic member being arranged in a first window to be compressed in response to relative rotation between said first and second rotary members; a second elastic member being arranged in said first window to be compressed in response to relative rotation between said first and second rotary members, and to operate in series with said first elastic member, said second elastic member having a higher rigidity than said first elastic member; a frictional resistance generating mechanism being configured to generate a frictional resistance in a rotational direction between said first and second rotary members, said frictional resistance generating mechanism being arranged to operate in parallel with said first and second elastic members; and a frictional resistance suppressing mechanism having a rotating-direction space to prevent an operation of said frictional resistance generating mechanism in a predetermined angle range, said frictional resistance suppressing mechanism arranged to operate in parallel with said first and second elastic members.
