<p><P>PROBLEM TO BE SOLVED: To provide a structure of a joint member and a molding structure of the joint member capable of reducing the cost and simplifying the work in manufacturing a flange joint by molding. <P>SOLUTION: The flange joint 1 is composed of a flange member 2 and a pipe 3, a through hole 5 is formed on the flange member 2 to make the pipe 3 be penetrated theretrough. A boss insertion hole 20 is enlarged in a state of spreading toward the bottom in the direction to open a tip end part of the pipe 3 into the shape of a flare 18. On the other hand, a triangular pad 19 is formed in a state of being positioned at a back face-side enlarged hole part 18 of the through hole 5 at a back face 7 side of the flange member. The flange member 2 is fixed to positions at both ends of the through hole 5 in a state of holding the flange member 2 by the flare 18 at its one end side and by the pads 19 at the other end side. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
