Abstract
A brushless motor includes a stator including teeth each including a constricted portion on which a coil is to be wound, and a tip end portion including a confronting surface that faces a rotor and having a width greater than that of the constricted portion. A spacer includes closure members disposed between adjacent ones of the tip end portions, and fitted to the teeth so that the confronting surfaces of the teeth are exposed toward the rotor.
