PROBLEM TO BE SOLVED: To make it possible to prevent the jointed part of a PC board supporting part with a bearing retaining part from contacting a second gear and to shorten the height of a motor. SOLUTION: A stepped part 12 to a shaft direction heading for a printed circuit board is provided near the jointed part 6 of the board supporting part 4 and a bearing retaining part 5 on the board supporting part 4. While the arrangement of the jointed part 6 inside this jointed part prevents the contact of an electronic component 10 with the board supporting part 4 and the contact of a second gear 9 with the jointed part 6 without increasing the size in the shaft direction, it makes it possible to shorten the height dimension of a motor. |
