    摘要: To provide a bearing structure of a flat type brushless motor for floppy disk drive in which a stator is arranged in a plane shape and a disk acting as a rotor yoke rotates along the plane shape without the use of conventional ball bearings so that the bearing structure can be high in the rigidity, stable in the motion, and low in the cost. For having a maximum bearing length, the bearing structure comprises a support shaft arranged with its axis extending depthwisely of the motor and having two journal regions provided on both ends thereof and a recessed region thereof between the two journal regions; and a rotor shaft mounted in the center of the disk and having a cylindrical body thereof onto which the journal regions of the support shaft are rotatably fitted. Accordingly, the motor will minimize the frictional loss of the sleeve bearing and increase its operational life. Also, the steadiness (of deflection, inclination, and rigidity) in bearing action will be enhanced. The support shaft is embedded at its lowermost end in the base plate which is a mounting base of the motor so that its vertical orientation with relation to the base plate is maintained with much ease, thus contributing to the physical accuracy of the bearing structure. The bearing structure according to the present invention employs non of the high-priced ball bearings of any conventional structure and will minimize the cost of the flat type brushless motor.
