(57) Abstract At least in one side the inside screw mountain of 1st rotation direction direction having and it possesses the tube which has been attached the slit to part area at least, the adjustment sleeve is screwed in by the end of this tube, at that time through the spanner surface where on end side of drug link the ball and socket coupling casing shaft of the ball and socket coupling which exists is screwed in by inside screw Yamanouchi of the 2nd rotation direction direction of opposite, to the 1st rotation direction of the adjustment sleeve, at that time is just formed to the adjustment sleeve introducing the drug link for the automobile of the type whose orientation movement of the relative tube is possible vis-a-vis the ball and socket couplingIt does. The adjustment sleeve (1) has had at least one blind slit (2) and the tightening metallic parts where the tube (3) is locked on the overcoat surface (4), these tightening metallic parts lock the mutual position of these structural parts.
