Rear view mirror assembly for motor vehicle

A rear view mirror assembly for a motor vehicle comprising:

• a mirror case containing a pivot mounting,
• a reflective member mounted on the pivot mounting for angular movement within the mirror case,
• a drive housing located within the mirror case and formed in two parts, each of which comprises a base portion having a bearing surface formed on its inner surface and a peripheral side wall portion dimensioned so that part of the side wall portion of one part surrounds a corresponding part of the side wall portion of the other part when the two parts are assembled together,
• a jacking nut positioned between the bearing surfaces,
• glue inserted between the side wall portion of one part and the side wall portion of the other part so as to secure the two parts together with their respective bearing surfaces spaced apart by a distance determined by the size of the jacking nut,
• a jacking screw engaging in the jacking nut and having an end pivotally coupled to the rear surface of the reflective member at a location remote from said pivot mounting, and
• an electric motor located within the drive housing and arranged to drive the jacking nut for effecting variation in the extent of protrusion of the jacking screw from the drive housing so as to adjust the orientation of the reflective member relative to the mirror case,
• the two parts of the housing being shaped so that, before insertion of said glue, movement of the respective bearing surfaces towards one another is limited only by the jacking nut.
