Abstract
An exterior rear view mirror assembly for an automotive vehicle is provided including a bracket for attachment to a side portion of a vehicle, a mirror housing having a rear opening connected to the bracket and extending laterally therefrom, a mirror connected within the mirror housing generally adjacent the mirror housing rear opening, a water removal hole penetrating a bottom end of the mirror housing for allowing precipitation entrapped within the mirror housing to escape therefrom, a turbulent flow generator formed forwardly adjacent of the water removal hole to cause turbulent air flow past the removal hole to diminish wind noise being generated by the water removal hole.

An exterior rear view mirror assembly for an automotive vehicle comprising:
- a bracket for attachment to a side portion of a vehicle;
- a mirror housing having a rear opening, connected to said bracket and extending laterally therefrom;
- a mirror connected within said mirror housing generally adjacent said mirror housing rear opening;
- a water removal hole penetrating a bottom end of said mirror housing for allowing water entrapped within said mirror housing to escape therefrom;
- a turbulent flow generator formed on said mirror housing forwardly adjacent of said water removal hole to cause turbulent air flow past said removal hole to diminish wind noise being generated by said water removal hole.

- a mirror connected within said mirror housing generally adjacent said mirror housing rear opening;
- a water removal hole penetrating a bottom end of said mirror housing adjacent a forward end of said mirror housing for allowing water entrapped within said mirror housing to escape therefrom, said mirror housing bottom end forward of said water removal hole having a generally rising slope;
- and
- three turbulent flow generators formed on said mirror housing forwardly adjacent of said water removal hole to cause turbulent air flow past said water removal hole to diminish noise being generated by said water removal hole, said turbulent flow generators having a generally triangular cross-sectional shape with a longest leg of said triangle being generally adjacent to said lower end of said mirror housing, said triangular turbulent flow generators extending longitudinally along the travel direction of said vehicle and the two turbulent flow generators bracket said water removal hole.
