<p>PROBLEM TO BE SOLVED: To abut a bearing on the top of a rotor bush and the bottom of a stator frame, by positioning the upper part in insertion space, and making its lower part include a globular bearing to be accommodated in the storage space. SOLUTION: Storage space 311a with its top open is made inside a stator frame 311. Then, a rotor 320 is equipped with a rotor bushing 321 and a rotor magnet 322 provided at the periphery of the rotor bushing 321. Insertion space 321 a with its bottom open is made inside the rotor bushing 321. A part of the lower part of such a rotor bushing 321 is inserted into the storage space 311a. Then, this motor is provided with a bearing to support the rotor bushing 321 rotatably between the insertion space 321a and the storage space 311a. This bearing 330 is globular, and the upper part is inserted into the insertion space 321a, and the lower part abuts on the bottom of the storage space 311a.</p> |
