A harmonic drive including a housing component (4) and a drive element (18) which is held on the housing component, can be deformed by a wave generator (14), is in the form of a flanged bushing and has a toothing region (17) having a cylindrical basic shape and a disc section (19) which adjoins the toothing region (17). Adjoining the disc section (19) there is a bushing section (20) which is concentric to the toothing region (17), overlaps the latter in the axial direction and is held interlockingly between a cylindrical edge section (21), which is thick-walled in comparison with the bushing section (20), of the housing component (4) and an intrinsically rigid component (22) which is likewise solid in comparison with the flanged bushing (18).
