ABSTRACT:
An electric motor has a rotor having an end portion and a recessed portion formed at the end portion. A rotational shaft is mounted to the rotor. A stator covers an outer peripheral portion of the rotor and forms a magnetic field that generates a torque around the rotational shaft to thereby rotate the rotational shaft and the rotor. A bearing rotatably supports the rotational shaft and is entirely spaced-apart from the end portion of the rotor in an axial direction of the rotational shaft. A slider is slidably mounted around the rotational shaft and supports rotation of the rotational shaft about a rotational axis thereof. The slider is interposed between the bearing and the rotor so that a portion of the slider is entirely contained in the recessed portion of the rotor and the remaining portion of the slider is disposed in the space between the bearing and the rotor and in contact with the bearing.
