Patent number: 7147334Abstract: When a vehicle mirror assembly is assembled, a bracket is firstly set as an assembling reference member, disposed on a bracket jig and positioned with respect to the bracket jig. Next, a retracting unit, a mirror surface adjustment unit, a door mirror stay and a mirror are mounted to the bracket. Finally a door mirror visor is mounted to the bracket. The bracket is made common regardless of a vehicle type thus a fixed bracket jig can be used resulting in cost reduction. Further, as the door mirror visor is mounted in a final process, defects of the door mirror visor due to scratches can be reduced thereby improving the production efficiency.Type: GrantFiled: January 3, 2001Date of Patent: December 12, 2006Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Bunji Inagaki, Fuminori Teraoka, Hiroki Iwasa, Kiyoharu Iga, Michiyasu Yajima
