<P>PROBLEM TO BE SOLVED: To secure attachment intensity of a base portion of a motor and to prevent interference of a screw being a male screw with a circuit board. <P>SOLUTION: A static portion 3 of the motor includes: a stator 32 which is arranged at a periphery of a bearing mechanism 4 and faces a rotor magnet 22 in a radial direction; the base portion 31 which is positioned below the stator 32 and extends in a direction vertical to a center axis; and the circuit board 33 fixed to an upper face of the base portion 31. A female screw passing through the base portion 31 and the circuit board 33 are overlapped in a direction parallel to the center axis. A peripheral region of the female screw on the upper face of the base portion is positioned in a place lower than a circuit board placement region which is a region abutting on or close to the circuit board on the upper face. <P>COPYRIGHT: (C)2012,JPO&INPIT |
