<p>[PROBLEMS] To obtain a pipe joint coupling device which can increase the adjusting amount of core gap of pipe joints when they are coupled while saving the space. [MEANS FOR SOLVING PROBLEMS] The pipe joint coupling device comprises one pipe joint member (9) having a containing groove (27) in the outer circumferential surface, the other pipe joint member (8), a member (7) for supporting one pipe joint member, and a collar member (31) for clamping the supporting member in conjunction with a shoulder portion provided in one pipe joint member. An opening (7a) having a diameter substantially equal to the outside diameter of one pipe joint is formed in the supporting member, an elastic member (29) is contained in the containing groove, the opening edge (7b) of the supporting member faces the containing groove, one side face (7c) of the opening edge abuts slidably against the shoulder portion, the other side face (7d) of the opening edge abuts slidably against the end face (31a) of the collar member, one pipe joint member is displaced freely by the elastic member, width of the containing groove is set larger than the plate thickness of the supporting member, and when the pipe joint members are coupled, the elastic member pressed by the opening edge of the supporting member deforms to displace one pipe joint member for the supporting member.</p> |
