Damper device

A damper device comprising:

• a first rotation body, the first rotation body including:
• a first plate to which power is transmitted from a flywheel and that rotates about a rotation axis;
• a second plate that is disposed to face the first plate at a distance from the first plate and rotates integrally with the first plate about the rotation axis;
• and
• a second rotation body that rotates relative to the first rotation body about the rotation axis while expanding or contracting an elastic mechanism part disposed along a circumferential direction between the second rotation body and the first rotation body, the second rotation body including an engagement portion protruding radially outward at an outer peripheral edge of the second rotation body,
• wherein the first plate includes a first drawn portion recessed in a direction from a first main surface of the first plate toward the second plate, and
• the second plate includes a second drawn portion that is provided to face the first drawn portion, is recessed in a direction from a second main surface of the second plate toward the first drawn portion, and is fixed to the first drawn portion by using a fastening member, and
• the first drawn portion and/or the second drawn portion comes into contact with the engagement portion of the second rotation body in a state of relatively rotating with respect to the first rotation body, and restricts further rotation of the second rotation body in a direction in which the elastic mechanism part is contracted.
