PROBLEM TO BE SOLVED: To fix a rotation detection sensor at a predetermined position through high-accuracy positioning in a motor.SOLUTION: A rotation detection sensor 22 constituting a motor 10 is disposed in such a manner that a plurality of holder holes 62 oppose a boss 36 of a cover member 28, and the rotation detection sensor 22 is positioned with respect to the cover member 28 by fitting a fitting part 48 of a holder 44 inserted through the holder holes 62 to a fitting hole 42 of the boss 36. By threading a mounting bolt 40 inserted into a through hole 38 of the boss 36 into a screw hole 46 of the holder 44, the rotation detection sensor 22 is held between a flange part 52 of the holder 44 and the cover member 28. In such a case, even if a case 60 of the rotation detection sensor 22 is made of a resin material, an axial force of the mounting bolt 40 is applied to the cover member 28 and the holder 44 made of a metallic material, such that cracking or the like may also be prevented. |
