A position adjusting device for a shoulder belt in a seat belt assembly includes a belt anchor into which the shoulder belt is loosely passed, an anchor support block supporting the belt anchor, a guide rail slidably holding the anchor support block, and a straight screw member which is arranged along a longitudinal direction of the guide rail and is screwed into the anchor support member, so that the anchor support block may be moved along the guide rail by the rotation of the screw member. A surface layer of solid lubricant is formed on at least one of thread surfaces of the screw member and the anchor support block. |
