1. A damper comprising:
a first rotary member, which has a side plate having a disc-shape, a cylindrical portion that is extended in an axial direction from an outer circumferential edge portion of the side plate, and first abutment portions that are provided apart from each other in a circumferential direction; a second rotary member, which has second abutment portions that are provided apart from each other in the circumferential direction, and which is disposed rotatably relative to the first rotary member; at least one elastic member that transmits torque between the first rotary member and the second rotary member; a first seat member, which is disposed between the elastic member, and the first abutment portion and the second abutment portion on a counter-rotating direction side of the first rotary member, and which is configured to slide on an inner circumferential surface of the cylindrical portion as the first rotary member and the second rotary member rotate relatively; a second seat member, which is disposed between the elastic member, and the first abutment portion and the second abutment portion on a rotating direction side of the first rotary member, and which is configured to slide on the inner circumferential surface of the cylindrical portion as the first rotary member and the second rotary member rotate relatively; and a sticking preventing mechanism, which converts part of a radially outward force generated by a centrifugal force into a restoring force of the elastic member in the circumferential direction to thereby prevent sticking of the first seat member and the second seat member to the inner circumferential surface. |
