<p>An electrically powered retractable door mirror in which a horizontal worm gear can rotate securely and smoothly by making the horizontal worm gear less affected by building differences between a frame body and a motor installation component is provided. On the under surface of an outer plate 50, horizontal worm gear bearings 76, 78 are provided. In the horizontal worm gear bearings 76, 78, a notch 86 is formed. By fitting shank portions 36a, 36b of the horizontal worm gear 36 through the notch 86, by deflecting the horizontal worm gear bearings 76, 78, into a space inside the bearing 84 of the horizontal worm gear bearings 76, 78, the horizontal worm gear 36 is fixed on the horizontal worm gear bearings 76, 78. At the bottom inside the box 28, flexure control portions 80, 82 are provided. While the outer plate 50 being installed on the frame body 14, the flexure control portions 80, 82 controls flexure of the horizontal worm gear bearings 76, 78 by catching the horizontal worm gear bearing 76, 78 from both sides of the horizontal worm gear bearing.</p> |
