ABSTRACT:
A method is disclosed for attaching an electric power outer mirror-housing device for a vehicle to the vehicle. The housing device includes a shaft carrying an outer mirror and a driving mechanism. The driving mechanism includes a motor, a worm gear, a helical gear inserted around the shaft slidable along an axial direction of the shaft, and a clutch holder engaged with the helical gear and adapted to transmit a turning force of the helical gear via the worm gear to the shaft. The method includes setting twisting directions of the helical and worm gears so that when the housing device is attached to a given portion of the vehicle, a turning force may be applied upon the shaft, in a direction opposed to a pressure of wind flowing from a front side to a rear side of the vehicle, by motion of the helical gear relative to the worm gear owing to vibration of the vehicle, and attaching the housing device to the above given portion of the vehicle.
