Abstract
A pipe joint coupling apparatus has first and second pipe joint members coupled to each other, a plate-shaped support member with an opening through which the first pipe joint member extends, and an elastic member accommodated in an annular groove formed in the outer surface of the first pipe joint member. The support member is clamped between a shoulder part formed on the outer surface of the first pipe member and a collar member disposed about the first pipe joint member such that the edge of the opening of the support member engages the elastic member. The width of the groove is greater than the width of the support member to allow the first pipe joint member to be radially displaced relative to the support member with the opening edge partially and radially entering into the annular groove while deforming the elastic member.
