<p><P>PROBLEM TO BE SOLVED: To provide a flange joining device capable of easily preventing reduction in fastening force without being hindered by an apparatus associated to a pipe when the bending moment is applied to the pipe joined to a flange. <P>SOLUTION: An outer peripheral part of a flange F of one tap water pipe 2 has a projection piece 12 extending by getting over a part of an outer peripheral part of a flange F1 of the other tap water 10, and a pressing bolt 14 is arranged toward the axis L of a tape water pipe 10 in this projection piece 12 so as to freely advance and retreat. Since a tapered part 14b for interposingly pressing both flanges F and F1 when pushing in this part toward the axis L is formed in a tip part of this pressing bolt 14, fastening force can be easily strengthened without being hindered by the apparatus associated to the tap water pipes 2 and 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
