A brushless motor suppresses acoustic noise during rotation of a rotor without impairing its expected performance. Each of teeth (24) of a stator (23) includes a constricted portion (24a) on which a coil (25) is to be wound, and a tip end portion (24c) having a confronting surface (24b) that faces a rotor (22) and having a width greater than that of the constricted portion (24a). The brushless motor is furnished with a spacer (30) including a plurality of closure members (33) disposed between adjacent ones of tip end portions (24c), and fitted to the teeth (24) so that the confronting surfaces (24b) of the teeth (24) are exposed toward the rotor (22).
