Abstract

A support (2) which serves for fastening a pointer (1) on a pointer shaft has, towards the top, a holding part (12) which is developed as an expansion rivet. The pointer (1) has a central passage (13) through which the holding part (12) engages. A cap (3) is provided with an expansion pin (14) which is adapted to be pushed from above into the holding part (12) when the cap (3) is mounted. In this way, the expansion rivet is expanded and the pointer (1) is thereby attached firmly to the support (2). A projection (16) on the holding part (12) which engages into a recess (17) in the pointer (1) determines the exact angular position of the pointer (1) with respect to the holding part (12).
