<P>PROBLEM TO BE SOLVED: To provide a motor in which beating noise is suppressed without displacement of a shaft toward a bearing member or urging of the shaft in a shaft direction, and an increase in size is suppressed. <P>SOLUTION: A motor comprises: motor cases 7 and 8; exciting coils 5 and 6 disposed in the motor cases; a rotor magnet 1 disposed inside the exciting coils in a radial direction; a shaft 2 rotating along with the rotor magnet; and a bearing member 10 held by the motor cases, and for rotatably supporting the shaft. The bearing member has a plurality of support portions 10b abutting on the outer peripheral surface of the shaft in a circumferential direction. Each of the support portions is formed so as to be elastically deformable in the radial direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
