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 tile hub flange 6 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 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 6.
