Abstract

The cylindrical element has a chamfer (5) at one end and has an aperture (6) parallel to the axis of the element at the other end for receiving the end of the spring and defined by two wings (7, 8) one of which (7) forms a stop, while the other (8) is longer and can be deformed to form an inclined surface relative to the axis of the element and axially blocking the end of the element. The external surface of second wing (8) serves to prevent the second turn of the spiral spring from contacting the spring end. The element has a flat (4) at one side, with the aperture provided in this flat (4).
