Abstract
A push button connection for an injection device comprising a push button (10) and a driving part (20). The two parts of the push button connection are mounted to each other and is relatively rotatable to each other. In order to minimize the friction occurring between the push button and the driving part when relatively rotated forces are transmitted via a pivot bearing (18, 22). In order also to minimize the effect of forces appearing dislocated from the center line a number of radial bearings (13, 23; 14, 25) having a little friction diameter is provided.
