Abstract

The invention relates to a spring element (10) for compensating for axial play in a motor shaft of an electric motor. The invention proposes embodying such a spring element (10) out of plastic and of one piece with a stop disk (12), which is connected via spring arms (14) to a support foot (16), and placing it, along with the support foot (16), onto a support sleeve (18) with which the spring element (10) can be press-fitted onto the motor shaft. The invention has the advantage that it eliminates the axial play in the motor shaft of an electric motor with a spring element (10) that is inexpensive to manufacture and easy to install (FIG. 1).
