<P>PROBLEM TO BE SOLVED: To inhibit occurrence of displacement on a stator side, even if large molding pressure is applied at resin molding. <P>SOLUTION: A pump includes a stator 4 wound with a coil 3, a rotor 7 having a magnet 6, an impeller 20, a separating plate 8, and a pump case 22 forming a pump chamber 21 in which the impeller 20 is accommodated. In the stator 4, the coil 3 is wound on an insulating cover 15 which covers a stator core 14. The separating plate 8 has a separating plate side protrusion 34, and the insulating cover 15 has a stator side protrusion 31. The separating plate side protrusion 34 makes contact with the stator side protrusion 31, so that the stator 4 is positioned relative to the separating plate 8. Under the positioned condition, the stator 4 is resin molded. <P>COPYRIGHT: (C)2013,JPO&INPIT |
