Claims

[Scope of utility model registration request]

In an electric motor in which a rotor shaft of a rotor is rotatably supported by a bearing disposed on one side of a stator core, a spring is attached to the rotor shaft that protrudes outward from the stator core from the bearing. A ring-shaped spring washer is formed by forming a plurality of fixing pieces with a diameter slightly longer than the diameter of the rotor shaft, and an end play setting plate is arranged between the end play setting plate and the bearing end surface. Attach using press-fitting means with the
A cantilever bearing electric motor characterized in that, after the end play setting plate is removed, the spring washer is irremovably held at a fixed position on the rotor shaft via a plurality of fixing pieces.
