DRIVING DEVICE FOR ADJUSTING MIRROR GLASS SUPPORT PIVOTALLY MOUNTED IN MIRROR CASING OF VEHICLE REARVIEW MIRROR

摘要

PURPOSE: To assure an exact seat of a warm gear within a single holder by making an inner diameter of an annular collar be slightly smaller than an outer diameter of a cylindrical region of a connecting member and by making an angle that the inner flank of the annular collar forms with a transverse cross-sectional plane be in a range of 30-60 degrees. CONSTITUTION: Convex guide surfaces 13 and 14 corresponding to guide surfaces 7 and 8 of a holder are formed within an inner flank below an annular slot 11 and at a down end of a connecting member 10 and these surfaces are co- axially disposed to have a common center. There is formed a space between the cylindrical region 6 of the holder and the cylindrical region 12 of the connecting member 10 in which a warm gear 4 is revolvable. The markαindicates an angle which the inner flank of the annular collar 9 forms with the transverse cross-sectional plane of the connecting member 10.
