PROBLEM TO BE SOLVED: To relieve the load of a bearing supporting a shaft, protect the bearing from breakage, and improve the verticality and fixing strength of the shaft. SOLUTION: A motor 1 has a stator 2, a board holding member 5, a shaft fixing member 6, a shaft 60 fixed to it, a board 7, an attachment plate 6, a rotor 9, screws 10 and a washer 11. The stator core 3 of the stator 2 has a plurality of poles 31 arranged radially. Each pole 31 is composed of an arm part 32, on which a coil is wound and a plate-shaped pole end part 33 which is folded in a direction approximately perpendicular to the arm 32. The rotor 9 is composed of a cylindrical permanent magnet 91, a cup-shaped yoke 92, a pulley 95 attached integrally to the yoke 92 and a bearing 94 fitted to the inside of the pulley 95. The shaft 60 is inserted into the bearing 94 and is supported rotatably. |
