摘要：PROBLEM TO BE SOLVED: To provide a motor shaft assembly. SOLUTION: The shaft assembly includes a shaft tube 34, a bearing 32, a shaft 41, and at least two engaging rings. The shaft 41 has the tip part 421 and the groove part 42. At least two or more engaging rings are arranged at the groove part 42 of the shaft 41 and they include first/second engaging rings 45, 46. The first engaging ring 45 is metallic and the second engaging ring 46 is non-metallic. The material strength of the first engaging ring 45 is larger than that of the second engaging ring 46. The first engaging ring 45 is utilized for supporting the shaft 41 and arranging it at a prescribed position, and the second engaging ring 46 is utilized for relaxing the shocks to the shaft 41. Thus, problems such as noise of motor, movement of position of rotor, and separation from bearing can be solved simultaneously. Consequently, the stability of the motor can be improved.
