。 A first yoke and a second yoke each having a plurality of serrated pole pieces each having a tapered shape and a substantially arcuate cross section are provided at a predetermined angular interval, and are combined with each other with a predetermined gap apart from each other in a staggered manner. A ring-shaped coil bobbin is sandwiched between the first yoke and the second yoke, and tapered serrated pole pieces of the first and second yokes are provided on the inner peripheral surface side of the coil bobbin. A small motor, characterized in that a plurality of protrusions are formed at the predetermined angular intervals and have a circumferential width such that the yokes fit together and are separated by the predetermined gap, and are shorter than the overall axial length of the coil bobbin. .
