A stepping motor includes a pair of drive coils arranged to sandwich a
magnetic rotor in the axial direction of a rotor shaft in order to
decrease the motor size. The drive coils are configured to be annular
around the rotor shaft that extends in both directions from the magnetic
rotor. A pair of cylindrical yokes are provided to enclose the drive
coils. A pair of sintered bearings that support the rotational movement of
the rotor shaft are made of a magnetic material, and the cylindrical yokes
and the sintered bearings are formed together.
