<P>PROBLEM TO BE SOLVED: To provide a structure that can further suppress a size in an axial direction in an inner rotor type spindle motor than conventional ones. <P>SOLUTION: A disk support part 314A is positioned outside in a radial direction than an end part of a tooth 42A in a radial direction thereof, and is positioned inside in the radial direction than a coil 222A. The end portion of the tooth 42A located inside in the radial direction, the disk support part 314A and the coil 222A are overlapped with each other in the radial direction. Therefore, at least a part of the disk support part 314A is disposed between the end portion of the tooth 42A located inside in the radial direction and the coil 222A. This suppresses the height of a first support surface 611A with respect to a stator core 221A. Consequently, the size of a spindle motor 11A in an axial direction thereof can be suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
