A damper device comprising: a pair of first plates that are provided at positions separated from each other in an axial direction of a rotation axis (Ax) and that are configured to be rotatable integrally with each other around the rotation axis in a state where the pair of first plates intersect the rotation axis; a second plate that includes a portion positioned between the pair of first plates, that has an opening, and that is configured to be rotatable around the rotation axis in a state where the second plate intersects the rotation axis; an elastic member that is provided between the first plate and the second plate, and that is elastically deformed at least in a circumferential direction of the rotation axis; and a third plate that has a first portion which is positioned on an inner side of the opening of the second plate and which is coupled to the pair of first plates in a state where the first portion is interposed between the pair of first plates from both sides in the axial direction, and a second portion which is positioned on an outer side of the opening of the second plate, and that is configured to be rotatable around the rotation axis in a state where the third plate intersects the rotation axis, wherein the first portion and an inner side end surface of the opening are configured to be capable of coming into contact with each other, and wherein when the first portion and the end surface come into contact with each other, the first plate and the third plate, and the second plate are configured so that a range of relative rotations around the rotation axis is limited, characterized in that at least one of the pair of first plates and the portion of the second plate positioned between the pair of first plates are configured to be mutually and relatively rotatable around the rotation axis via a bearing. a pair of first plates that are provided at positions separated from each other in an axial direction of a rotation axis (Ax) and that are configured to be rotatable integrally with each other around the rotation axis in a state where the pair of first plates intersect the rotation axis; a second plate that includes a portion positioned between the pair of first plates, that has an opening, and that is configured to be rotatable around the rotation axis in a state where the second plate intersects the rotation axis; an elastic member that is provided between the first plate and the second plate, and that is elastically deformed at least in a circumferential direction of the rotation axis; and a third plate that has a first portion which is positioned on an inner side of the opening of the second plate and which is coupled to the pair of first plates in a state where the first portion is interposed between the pair of first plates from both sides in the axial direction, and a second portion which is positioned on an outer side of the opening of the second plate, and that is configured to be rotatable around the rotation axis in a state where the third plate intersects the rotation axis, wherein the first portion and an inner side end surface of the opening are configured to be capable of coming into contact with each other, and wherein when the first portion and the end surface come into contact with each other, the first plate and the third plate, and the second plate are configured so that a range of relative rotations around the rotation axis is limited, characterized in that at least one of the pair of first plates and the portion of the second plate positioned between the pair of first plates are configured to be mutually and relatively rotatable around the rotation axis via a bearing.
