<P>PROBLEM TO BE SOLVED: To suppress evaporation of a lubrication oil in a bearing mechanism of a motor. <P>SOLUTION: A motor includes a rotation part, a bearing part, and a static part. Between an upper part of the bearing part and the rotation part, there is configured a seal part at which an interface of a lubrication oil is positioned. Between a hub cylinder part 314 and the upper part of the bearing part, a cylinder gap is configured. Between a lower part of the hub cylinder part 314 and an upper part of a stator fixing part, there is configured a first connection gap 71 having a portion axially extending, or downward, radially and outward inclined. Between a lower end of the hub cylinder part and a radial inner portion of a stator core, there is configured a second connection gap 72 radially and outward extending from the first connection gap 71. <P>COPYRIGHT: (C)2013,JPO&INPIT |
