PROBLEM TO BE SOLVED: To reduce vibration due to electromagnetic excitation force generated in a motor. SOLUTION: The motor 1 is mainly provided with a fixing member 11, a rotating member 12 and a bearing mechanism 13 for rotatably supporting the rotating member 12 on the fixing member 11. The motor 1 is also provided with a stator 14 mounted to the fixing member 11 and a rotor magnet 15 mounted to the rotating member 12. The fixing member 11 mainly comprises a sleeve 16 and a fixing member main 17. The fixing member main 17 is a circular plate member fixed to a lower part of the sleeve 16 and has a cylindrical branch 17a upwardly extending in the shaft direction. The stator 14 is mounted to the branch 17a through a cylindrical supporting member 18. The supporting member 18 is mounted to a free end of the branch 17a and has a protrusion 18a extending in the outer circumferential direction of the branch 17a and a cylindrical part 18b formed at the outer circumferential end and downwardly extending in the shaft direction.
