摘要： A bearing apparatus for use in an floppy disc drive device motor having a sleeve bearing and a thrust bearing is provided which is characterized in that there is provided a thrust bearing having such a convex portion, a projection, or a concave portion that makes the rotation shaft of the motor inclined with respect to the center axis of the sleeve bearing. Therefore, the rotation shaft ofa motor can be forcibly inclined with the rotation shaft and the sleeve bearing being kept in contact with each other. In addition, it is possible to reduce deviation in inclination of the motor rotation shaft and to ensure electric conductance between the motor rotation shaft and the motor body. These advantages areattained by a specific structure in which a projection, a convex portion, or a concave portion is provided at the thrust bearing, and therefore, the structure is simple and requires low costs.

摘要翻译：提供了一种用于具有套筒轴承和推力轴承的软盘驱动装置马达的轴承装置，其特征在于，提供了一种具有这种凸起部分，凸起或凹陷部分的推力轴承，电机的轴相对于套筒轴承的中心轴线倾斜。因此，电动机的旋转轴能够在旋转轴与套筒轴承保持接触的状态下被强制地倾斜。另外，可以减小电动机旋转轴的倾斜偏差并确保电动机旋转轴与电动机本体之间的导电性。这些优点通过其中在推力轴承处设置凸起，凸起部分或凹陷部分的特定结构得以实现，并且因此该结构简单且需要低成本。
