<p>PURPOSE:To enhance the stability by positioning an annular collar inserted in the outer peripheral surface of an attaching and fixing part of a pipelike article, on the inner peripheral side of an arcuate part of an annular article fixing device, and by fastening and fixing the collar to the fixing part in a condition in which the collar is embraced by the arcuate part. CONSTITUTION:A metal panel is bent so as to form an arcuate part 12 for embracing the outer peripheral surface of a pipelike article P in the center part thereof. A metal panel is bend to form corrugation in which concave parts 19 and convex parts 20 are alternately arranged in cross-section in the circumferential direction, so as to obtain an annular collar 18. The collar 18 is inserted on the outer periphery of an attaching part of an annular article P after a pair of flanges 21a, 21b which define an opening of the collar 18 are widely opened. Further, the collar is positioned on the inner peripheral side of the arcuate part in an annular article fixing device in a condition in which protrusions 22a, 22b at the tip ends of the pair of flanges 21a, 21b are projected outward from a cutout part 17 of a fixture 11.</p> |
