PROBLEM TO BE SOLVED: To provide a motor obtaining a required torque even in flattening and miniaturization in the axial direction and reducing a rotational unevenness. SOLUTION: In a rotor 22, pectinate bodies are assembled oppositely in a space section K with a specified clearance in the axial direction to a coil unit 20. In the rotor 22, an internal annular section 24 erected and formed in the axial direction from an internal pectinate body 26 is assembled to the inner peripheral surface 21a of a coil case 21 and an external annular section 27 erected and formed in the axial direction from an external pectinate body 29 is assembled to the outer peripheral surface 21b of the coil case 21 so that they are opposed in the axial direction respectively.
