| Zusammenfassung: | A stator core includes a core back of a substantially annular shape. At a radially outer end portion of the core back four teeth are arranged radially. At the teeth , a coil is formed by winding a magnet wire via an insulator . A first insulator configuring a lower half of the insulator includes a first core back insulating portion , 1 first teeth insulating portion , and a first cylindrical portion . A hook portion is formed at the first core back insulating portion at radially outer side, and between the teeth . The magnet wire extracted from the coil is hooked on the hook portion . The magnet wire hooked on the hook portion is lead the magnet wire around the hook portion as a base, and is soldered to a land formed above a circuit board |
