ABSTRACT:
An improved ball joint structure for clamping a rear view mirror head tightly yet turnably on a supporting ball member includes a ball seat member and a body clamping member fixed at the outer and inner sides of housing wall portions bordering an opening in which a mirror supporting ball is disposed, a ball clamping member mounted on the body clamping member and having a contoured portion to grip the inner side of the ball, and means adjustable from outside the wall for holding the ball clamping member under a desired tension against the ball. The body and ball clamping members have coacting formations that limit displacement of the ball clamping member in the direction away from the ball.
