Abstract
A damper device includes a first member, a second member, an elastic member and a supporting member. The first member has two wall members separated from each other. The supporting member includes projections (preventing portion) that make contact with one of two wall portions (wall members) so as to prevent the supporting member and an elastic member from being inclined (falling, rotationally moving) in the axial direction.
Claims8
A damper device comprising:
- a first member that has two wall members separated from each other in an axial direction of a rotating axis and rotates about the rotating axis, the first member being provided with an opening having a first recess at a circumferential edge of the opening of the first member, the first recess being depressed in a circumferential direction;
- a second member that is located between the two wall members and rotates about the rotating axis, the second member being provided with an opening having a second recess at a circumferential edge of the opening of the second member, the second recess being depressed in the circumferential direction;
- an elastic member that is interposed between the first member and the second member and is elastically deformed at least in a circumferential direction of the rotating axis between the first member and the second member;
- a supporting member including a first supporting portion, a second supporting portion, a projection, and a preventing portion, the first supporting portion being supported by at least one of the first member and the second member, the second supporting portion supporting the elastic member, and the preventing portion making contact with at least one of the two wall members and the second member so as to prevent the supporting member from being inclined in the axial direction, the projection projecting from the first supporting portion in the circumferential direction and being accommodated in the first recess and the second recess.
