は回転を生じない。lIO is a tightening ring, which is fitted into the bolt 10 at the intermediate part between the socket 30 and the rear nut /3, and whose inner end is expanded to a tapered shape of 4t/3, and whose outer diameter is slightly smaller than the inner diameter of the pipe 30 to be used. and seven cuts tl in the axial direction.
Several thin-walled parts (two in the figure) are formed, and each part of the tightening ring 4t is pressurized by screwing the bolt 10 into the mounting member 0. At this time, the thin wall part '13f'l Z and the thread t bite into the rib 3, and no rotation occurs between the tightening ring qO and the socket 30 even if the bolt loosens a little thereafter.
