<p><P>PROBLEM TO BE SOLVED: To provide a brushless motor in which the workability and the assembling work of parts are simplified and which has a thrust bearing member having excellent reliability without the deformation of a bearing and without the leakage of a lubricant. <P>SOLUTION: A burring work is performed at the substantially center of a stator base 10 by a press, and a cylindrical part 11 as the base of the bearing housing of this motor is formed integrally with the stator base 10. The sleeve bearing 20 of a radial bearing is press injected and fixed to the inside 11a of this cylindrical part 11. Further, a stator S, to which a stator core 40 wound with a coil 30 made of a lead wire is fixed, is formed at the outside 11b of the cylindrical part 11. Incidentally, the thrust bearing part 60 of a rotary shaft 50 is molded integrally with the stator base 10 by the resin integrally molding process of an outsert molding method in the opening 11c of the cylindrical part 11 of the stator base 10, and receives the opposite output side end part of the rotary shaft 50. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
