An axial adjusting device including two discs (24, 29) which are rotatable relative to one another and coaxially supported relative to one another, between which discs (24, 29) and balls (35) are guided in pairs of ball grooves (34, 39) in the discs (24, 29), wherein the depth of the pairs of ball grooves (34, 39) is variable across the circumference of the discs; one of the discs (24, 29) is axially supported and one is axially displaceable against the returning forces of a resilient spring mechanism and at least one is drivable by a motor (11) which is incorporated into a housing (52) and whose motor shaft (12) is connected to a driving pinion (15), wherein the driving pinion includes a journal projection (16) which runs in a bearing (17) which is supported in the housing (52). |
