<p>PURPOSE:To provide a small-sized motor having a structure in which a brush is stably electrically bridged to a motor case in a simple structure. CONSTITUTION:The small-sized motor comprises a conductive motor case 1 fixed with a magnet to its inner surface, and a nonconductive case cover 7 for holding a brush unit in a structure that the case 1 is engaged with the cover 7. A ground terminal 6 formed substantially in a U-shaped state of a case contact piece 21 and a conductive contact piece 25 is provided, and a caulking groove 27 for caulking the end of the piece 21 with the cover 7 is provided. One of brushes is electrically bridged to the case 1 through the terminal 6.</p> |
