PURPOSE:To prevent the production of an improper motor by covering both radial side faces of a printed circuit board with the extensions of a molded holding plate. CONSTITUTION:A molded holding plate 13 has extensions 13c, 13d, which are respectively covered on inner and outer ends 12b, 12c of a printed circuit board 12, and an extension 13e, which is passed through a statinal hole 12d of the board 12, thereby holding the substrate 12 by the prescribed strength of a mold mounting plate 13. With the above structure, even if an error is produced in size of the inner and outer ends 12b, 12c of the board 12, it is absorbed by the extensions 13c, 13d, the substrate 12 is not engaged with the mold, thereby preventing the production of an improper motor. |
