    • PROBLEM TO BE SOLVED: To provide a stator structure of an outer rotor type motor capable of wiring in good workability by utilizing a space part formed on the outer peripheral side, with a magnetic pole tooth of a stator unit being missed without degrading insulation reliability of a coil lead drawn out of a coil.SOLUTION: Stator units 4a-4d which miss a pair of, upper and lower, magnetic pole teeth 7c and 7d, facing each other, of stator yokes 7a and 7b are laminated together, so that space parts 12a-12d being continued from the missing magnetic pole teeth positions are formed. Connector terminals 11a-11d arranged at the space parts 12a-12d are electrically connected to coil leads drawn out of the coil 6 of the stator units 4a-4d.
