<P>PROBLEM TO BE SOLVED: To provide a motor capable of surely performing retaining by a retaining member in a simple structure. <P>SOLUTION: A rotation part 4 of a motor 1 includes a rotor yoke 41 and a retaining member 6 fixed to a lid part of the rotor yoke 41, and the retaining member 6 includes a lower fixing part abutted to a lower surface of the lid part, a plurality of lower projection parts projecting downwards from the lower fixing part, a plurality of upper projection parts inserted to a plurality of lid part through-holes 81, and a plurality of retaining parts projecting inward or outward in the radial direction at the lower part of the plurality of lower projection parts and positioned near the lower part of a part of a static part 2 or a bearing mechanism 3. A through-hole forming part forming the respective lid part through-holes 81 includes at least one outer side contact part to be in contact with the part on the radial direction outer side of the upper projection parts and at least one inner side contact part to be in contact with the part on the radial direction inner side of the upper projection parts at a position different from the at least one outer side contact part in a circumferential direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
