Claim Text:
1. A clutch disk having a ring-shaped base body having at least one tooth protruding beyond the base body radially inward or radially outward, wherein the at least one tooth consists of a middle section, first and second transition sections, and first and second lugs, wherein first and second lateral faces are formed from the first and second lugs and extend in an axial direction and have a distance from one another in a circumferential direction, wherein the at least one tooth is formed to be integral with the base body and the first and second lugs by a deformation process, wherein the base body has a first surface as seen in the axial direction, and a second surface lying opposite the first surface in the axial direction, wherein the first and second transition sections and the first and second lugs are formed by double bending such that there are only two bending lines between the middle section and each lug and wherein the first and second lugs have first and second front faces, respectively, arranged at least approximately at a right angle to the axial direction, wherein the middle section aligns with the base body and the first and second transition sections are angular with respect to the middle section as a whole and connect the middle section with the first and second lugs, respectively, wherein the first and second lugs are arranged to be at least approximately at a right angle with respect to the middle section as a whole and with respect to the circumferential direction of the base body and protrude beyond the first surface as well as the second surface in the axial direction, and wherein an angle between the transition sections and the lugs is selected from a range between 45° and 80°.
