摘要： A disk drive 1 of the invention has through holes 27 formed in a turntable 4 in such a manner as to surround circumferentially a spindle 5, dislodgement preventive portions 28 provided to extend from a lower surface of a disk holding portion 9 towards a base portion 2 through the through holes 27, a hook locking portion 29 formed on an outer circumferential wall of a bearing holding portion 15 and hook portions 30 formed on distal end portions of the dislodgement preventive portions 28 which lie to a side of the base portion 2. In addition, the base portion 2 of the disk drive 1 of the invention includes a plurality of openings into which respective coils 20 are partially inserted and is configured such that an outer circumferential portion of a stator core 19a and the base portion 2 are spaced apart from each other at a predetermined interval.

摘要： This motor comprises a core, a drive coil wound on the core, a housing, and a stator having an insulator for insulating the drive coil formed one-piece with the housing. Further, the motor comprises a stator casing for encasing the stator, and a rotor disposed outside the stator. Inside the housing is disposed a bearing for supporting the rotary shaft of the rotor, and an oil retainer disposed so as to partially come in contact with the bearing is stored in a storing section provided in either one of the housing and the stator casing.
