Abstract

PROBLEM TO BE SOLVED: To provide a mirror surface angle adjusting device allowing reductions in man hours for assembly and in the number of part items. SOLUTION: In the mirror angle adjusting device 10, the retaining part 14 of a case 12 oscillatably retains a mirror body, and the mirror body is rotatably held against the ends of a pair of rods provided on the case 12. By driving a pair of motors in the case 12, the rods are displaced in the longitudinal direction of a vehicle to thereby cause the mirror body to oscillate about the retaining part 14 to adjust the angle of the surface of the mirror body. The grommets 18 of the case 12 prevent water from entering the case 12 from between each rod and the grommet 18. A sealer 22 in the case 12 prevents sound from being caused by the vibration of the motors 24. Since the grommets 18 and the sealer 22 are molded in two colors along with the case 12 and integrated with the case 12, man hours for assembly and the number of part items can be reduced.
