ABSTRACT:
A miniature motor comprising a rotor having a plurality of axially extending magnetic poles disposed on the outer periphery thereof in the circumferential direction, and a stator having two axially disposed coils wound on coil bobbins, in which flanges whose outside diameter is larger than the outside diameter of hollow cylindrical coil cores are provided on both ends in the axial direction of the coil cores, the coil bobbins having on one of the flanges projections protruding toward the outside in the axial direction of the coil cores are disposed in such a manner that the projections are directed toward each other, and that the projection on one coil bobbin faces the coil core of the other coil bobbin.
