- the plane plate 1 has in at least a first cross section 10 (eg, shown in Fig. 20), which extends parallel to the axial direction 5 and along a direction perpendicular to the axial direction 5 radial direction 11 between the receptacle 9 and the first guide surface 7 , At least a first region 12, in which a wall thickness 13 of the plane plate 1 changes continuously. In this case, the wall thickness 13 is determined in a direction parallel to the axial direction 5.
- This wall thickness 13 changes continuously, d. H. At each position adjacent to each other along the radial direction 11, the first region 12 has a respective other wall thickness 13.
- the first region 12 has a first center line 21 in the first cross section 10, the first center line 21 being at a first angle 22 to the radial direction. tion 11 runs.
- the first center line 21 is formed by the center points of the wall thickness 13 present at the respective radial position.
