Abstract
To prevent attachment in an inclined state, a coupling ring with an inner concave groove is fitted to an outer circumferences of abutting flange portions, and is fastened to reduce an inner diameter thereof so that an inclined surface formed on each side surface of the concave groove presses an inclined surface formed on an opposite surface of each of the flange portions. The pair of flange portions are coupled by force generated at the time of pressing. An attachment correcting surface is provided on each of the flange portions or each of the pipes so that, only where the coupling ring is attached and fastened in an orientation inclined at an angle equal to or larger than a prescribed angle, the attachment correcting surface is abutted to a part of the coupling ring prior to completion of the fastening so as to prohibit the part from being brought closer.
