Abstract
A coupling ring is provided, including a series of unit members with adjacent unit members rotatably coupled to each other, and a fastener coupling unit members on both ends to each other. A concave groove provided to extend circumferentially is externally fitted into an outer circumference of each of two opposing flanges. The unit members on the both ends are coupled to each other by the fastener to be turned into an annular state. The fastener is fastened to thereby press an inclined surface. The flanges are pressure-bonded to each other by forces generated during pressing. A stopper member is provided to restrict a separation angle between the unit member on one end and an adjacent unit member to fall within a certain angle in an open state in which the unit members on the both ends are not coupled to each other provided on at least one of the unit members.
