<P>PROBLEM TO BE SOLVED: To provide a brushless motor that can be reduced in thickness and size, and is high in dimensional accuracy from a fixing position of a the motor up to an axial core of the motor. <P>SOLUTION: In the brushless motor 1, a shaft 30 supported by a bearing 40 relatively rotates with respect to the bearing 40. The bearing 40 has a protrusion 41 which is attached to a bracket 50 having a hole 51 and engaged with the hole 51. The protrusion 41 is protruded to the attachment direction (arrow A-direction) of the bearing 40 with respect to the bracket 50. Since the protrusion 41 of the bearing 40 can be engaged with the hole 51 of the bracket 50, the brushless motor can be reduced in thickness and size. Furthermore, since the bearing 40 can directly be fixed to the bracket 50, the dimensional accuracy from the fixing position of the brushless motor up to the axial core (rotation center of the shaft 30) of the brushless motor is improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
