ABSTRACT:
One end of a shaft is fixed to a first portion of a housing. An eccentric rotor is located in the housing rotatably on the shaft. The other end of the shaft is fitted into a concave portion on a second portion of the housing, so the rotor may be assembled in the housing in a simple manner and radial movement of the shaft can be prevented without enlarging the fixing portion of the shaft. Even if the diameter of the shaft is small, the shaft can withstand an impact resulting from dropping of the motor.
