PROBLEM TO BE SOLVED: To provide a brushless motor, in which all of magnetic paths from a magnet magnetic pole functions as an effective magnetic path to a support and whose rotating torque is satisfactory. SOLUTION: A stator 10, which is composed of a support 14 radially extended from the center axis and of a coil 15 wound on a base part 14a of the support, is provided. In addition, a magnet magnetic pole 22, which is arranged in a ring shape so as to face the top face of the top part of the support 14, is provided. In addition, a rotor 20 which holds a magnet magnetic pole and which is composed of a cover 21 covering the stator is provided. A plurality of holes 21c are formed in the upper wall of the cover 21 so as to stride at a position, in which the magnet magnetic pole at the upper wall 21a of the cover is seen from the side of the upper wall and a position in which the tip face of the support, is seen from the side of the upper wall. |
