Abstract
A motor includes a rotor and a stator. A shaft of the rotor is received in a sleeve. A face of the sleeve and a face of the shaft, that are opposed to each other, form a bearing supporting the rotor in a rotatable manner relative to the stator. A sleeve-retaining portion that retains the sleeve has a bottom portion opposed to an axial end of the sleeve. A magnet holder is arranged in the bottom portion to accommodate an attracting magnet magnetically attracting the axial end of the shaft. The magnet holder is held between the axial end of the sleeve and the bottom portion of the sleeve-retaining portion.
