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. <MATH> |
