Abstract:
1. A damper device comprising: a first rotating member having a rotation axis and being rotatable; a second rotating member rotatable about the rotation axis relative to the first rotating member via an elastic member, wherein the first and second rotating members include a driving-side rotating member and a driven-side rotating member, and wherein the driven-side rotating member is formed by at least two members that guide the elastic member and sandwich the driving-side rotating member; an axial-direction support portion that supports the first rotating member and the second rotating member in a direction of the rotation axis with respect to each other; and a radial-direction support portion that is disposed on a circumference, whose distance from the rotation axis is substantially equal to a distance of the axial-direction support portion from the rotation axis, and that supports the first rotating member and the second rotating member in a radial direction with respect to each other, wherein the axial-direction support portion and the radial-direction support portion are alternately disposed about a circumference of the clutch and are disposed respectively at substantially equal intervals, wherein each one of the at least two members of the driven-side rotating member has a first tab and a second tab that is provided inwardly of an outermost periphery of the first tab, and a portion of the first tab which sandwiches the driving-side rotating member includes the axial-direction support portion, and the second tab includes the radial-direction support portion.
