Abstract
A damper mechanism 4 has an input rotary member 2, a hub flange 6, a large coil spring 8 and a friction generating mechanism 5. In a state in which the input rotary member 2 is twisted to one side in the rotational direction with respect to the hub flange 6, the friction member is pressed in the rotational direction against the hub flange 6 in a state in which at least part of the friction member has been elastically deformed in the relational direction, so that the friction member and the hub flange 6 function as an integral member in the rotational direction. In a state in which the input rotary member 2 is twisted to one side in the rotational direction with respect to the hub flange 6, the friction member is capable of relative rotation with respect to the hub flange.
Claims20
A damper mechanism, comprising:
- a first rotary member;
- a second rotary member being disposed rotatably within a range of a first angle with respect to the first rotary member;
- a third rotary member being disposed rotatably with respect to the second rotary member;
- an elastic member elastically linking the first and second rotating members in a rotational direction;
- and
- a friction generating mechanism being disposed between the first and second rotating members and having a friction member frictionally engaging the first rotary member,
- in a state in which the second rotary member is twisted to a first side in the rotational direction with respect to the third rotary member, the friction member being pressed in the rotational direction against the second rotary member in a state in which at least part of the friction member has been elastically deformed in the rotational direction, so that the friction member and the second rotary member function as an integral member in the rotational direction, and
- in a state in which the second rotary member is twisted to a second side opposite to the first side in the rotational direction with respect to the third rotary member, the friction member being configured to rotate relatively with respect to the second rotary member within a range of a second angle that is smaller than the first angle.
