Damper device

A damper device comprising:

• a first rotating member to which power of an engine is input and that is rotatable around a rotational axis extending in an axial direction;
• a second rotating member that is rotatable around the rotational axis relative to the first rotating member;
• and
• a coil spring that is compressed between the first rotating member and the second rotating member, wherein
• the first rotating member includes:
• a first plate member forming an engine-side attachment surface that faces to an engine side in the axial direction and that is perpendicular to the rotational axis;
• and
• an annular member that has an annular shape around the rotational axis when viewed in the axial direction and that is coupled to the first plate member,
• the first plate member further forms an offset surface that faces to an engine side in the axial direction and that is offset from the engine-side attachment surface to a side separated from the engine in the axial direction,
• a radial-direction area of the offset surface includes an area being on a radial-direction outer side of the engine-side attachment surface and on a radial-direction inner side of the coil spring, and
• the annular member overlaps with the offset surface when viewed in the axial direction.
