Abstract

An arrangement for fixing a tubular element, such as a shaft, that is provided with a bore and a flange in position with respect to plate element involves the use of a ball that pressed into the bore in the tubular element. To achieve a simple fixation that is secure in both axial directions, the plate element is fixed on one side by the flange of the tubular element and on the other side by the bulge that is created through insertion of the ball into the bore in the tubular element. The ball has a greater diameter than that of the bore in the tubular element so that insertion of the ball into the bore causes the tubular element to become enlarged, thus forming the bulge.
