The squared end of a drive rod 20 of a reclining chair operating mechanism is inserted into a square cavity 30 in the side of an end 16 of operating handle 12 of polypropylene. A screw hole 28 goes through the edge of the handle to intersect the square cavity, the cavity having a slot 32A extending into side opposite the entry of the screw hole. A screw with head 22, unthreaded shank 22a, threaded portion 22b, and lead in end 22b is inserted into the screw hole so that the thread engages and threads the aperture in the rod end and into the plastic of the slot on the other side, the leading end of the screw being within the slot, and the shoulder 29 between the shank 36 and the threaded portion of the screw is screwed up tight against the shoulder 28a in the hole. |
