Abstract
The invention relates to an indicator apparatus (1) having a ring pointer (2), which is mounted such that it can move in the circumferential direction (5), and having a drive unit (3), which drives the ring pointer (2) in the circumferential direction (5), wherein the ring pointer (2) interacts with a stop (10) in a manner limited in terms of its circumferential movement. Particularly in the case of synchronization, radial disengagement often occurs in conventional ring pointer arrangements, and the aim of the invention is to prevent this. In order to solve the problem, the invention proposes arranging the stop (10) directly next to the drive unit (3). The critical advantage of this is that the tangential force on the ring pointer (2) from the drive unit generates an only small disengagement moment on the ring pointer (2).
