Abstract
A damper mechanismhas an input rotary member, a hub flange, a large coil springand a friction generating mechanism. In a state in which the input rotary memberis twisted to one side in the rotational direction with respect to the hub flange, the friction member is pressed in the rotational direction against the hub flangein 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 flangefunction as an integral member in the rotational direction. In a state in which the input rotary memberis twisted to one side in the rotational direction with respect to the hub flange, the friction member is capable of relative rotation with respect to the hub flange.
