in the carrier disk 18 and latches behind it the end cap 24 serves to cover the omega spring 15 and the carrier disk 18 and especially to cover the open articulation area of the inclination adjustment fitting 1 in order to protect this area from contamination especially during painting operations the end cap 24 is provided with a hub formed by two tabs 27 which can be positively inserted into a central recess 28 in the carrier hub 17 in this arrangement the inner surfaces of the tabs 27 rest against an out of round cross section 29 for the positive accommodation of a drive shaft that is not illustrated here see fig5 this drive shaft is used to introduce a quantity of torque to the inclination adjustment fitting 1 and can be a part of a hand operated wheel or a motor driven shaft at the ends of the tabs 27 on the end cap 24 latching tabs 27 1 that project radially outward are provided once the tabs 27 have been inserted into the carrier hub 17 these latching tabs latch behind a shoulder in the recess 28 as is shown in fig6 when the drive shaft is installed the tabs 27 can no longer be compressed radially inward which serves to ensure the engagement between the tabs 27 1 and the shoulder the configuration of the end cap 24 that is described here in conjunction with the carrier hub 17 ensures.
