Abstract
A bearing installation for a Floppy Disk Driver motor which is simple in structure and high in accuracy of a rotating action of a rotary shaft, thus hardly impairing the read and write characteristics of a Floppy Disk Driver device. A bearing installation for a Floppy Disk Driver motor includes a protective cap mounted to one side of the motor; a first pivot bearing arranged for free and axial movements on a rotary shaft of the motor relative to the protective cap; a thrust spring urging axially the first pivot bearing on the rotary shaft of the motor; the rotary shaft fixedly mounted on a rotor of the motor, and supported pivotally at one end by the first pivot bearing and at the other end by a second pivot bearing fixedly mounted on a platform on which the motor is installed; a lead screw joined to an outwardly extending portion of the rotary shaft from the motor; and a positioning bushing arranged through which the rotary shaft fixed to the motor extends without direct contact with and closely fitted into a positioning hole provided in a plate to which the motor is secured.
