Abstract:
A damper mechanism comprising:a first rotary member; a second rotary member being rotatable with respect to said first rotary member; a first elastic member coupling said first and second rotary members together in a rotating direction, being compressed in the rotating direction when relative rotation occurs between said first and second rotary members, and being compressed on positive and negative sides of torsion characteristics; and a second elastic member coupling said first and second rotary members together in the rotating direction, being compressed in the rotating direction when relative rotation occurs between said first and second rotary members, being arranged to operate in parallel in the rotating direction with respect to said first elastic member, being compressed on said positive side of said torsion characteristics, and being compressed on said negative side of said torsion characteristics only in a range when relative rotation between said first rotary member and said second rotary member exceeds a predetermined torsion angle; and a friction generating mechanism being configured to generate a friction resistance only when said second elastic member is compressed in the rotating direction.
