ABSTRACT:
An axial securing device for the shaft of a small motor in which one end of the shaft is solidly connected with a rotor and the other end is supported in a thrust bearing of a stator. A securing element is locked into an annular groove of the shaft. The securing element has an inwardly directed bulge and a cylindrical projection. When the shaft is inserted, the securing element is pushed in front of the annular groove during the radial extension and locks into the annular groove by itself during further axial movement. The projection is so dimensioned so that through this movement its underside surrounds the contact surface of the shaft end.
