1. A damper device comprising:
a first rotor including a contact surface, the contact surface facing a circumferential direction, the contact surface extending in a radial direction;
a second rotor disposed to be rotatable relative to the first rotor, the second rotor including a stopper surface extending in the radial direction, the stopper surface opposed to the contact surface at an interval in the circumferential direction; and
an elastic member configured to elastically couple the first and second rotors,
the first rotor including a first plate and a second plate, the first plate being disposed on a first side of the second rotor in an axial direction, the second plate being disposed on a second side of the second rotor in the axial direction, and
the second rotor being disposed between the first plate and second plate in the axial direction,
the first plate including a first plate body, a connecting portion, and an attachment portion, the connecting portion extending from an outer peripheral part of the first plate body toward the second plate in the axial direction, the attachment portion extending radially outward from a distal end of the connecting portion, and
the attachment portion including the contact surface and protruding toward the stopper surface in the circumferential direction relative to the connecting portion such that the attachment portion is wider than the connecting portion in the circumferential direction.
