<p><P>PROBLEM TO BE SOLVED: To provide a branch joint easily mountable to a connected pipe. <P>SOLUTION: A joint body 1 is formed with a connection port 5 at one end, and a deformation preventing cylinder part 6 having an opening part 7 at the outer periphery, at the other end. A locking body 2 rotatably fitted to the joint body 1 is provided with a locking claw part 15 having a plurality of slits 14, and a cylindrical locking part 16 projected inward from a connection hole of the connected pipe is formed at the remaining part. A support part 17 abutting on the inner peripheral edge part of the connection hole of the connected pipe is formed at the edge of the cylindrical locking part 16. A mounting body 3 fitted to the locking part 2 has a saddle part 27 facing the outer peripheral edge part of the connection hole, and the saddle part 27 is provided with a slip-off preventing protrusion part 30 of a packing 28 for holding a clearance between the connection hole and the outer peripheral edge part in a water tight manner. A nut body 4 screwed with the locking body 2 is formed with an annular recessed groove 35 on the inner peripheral surface so as to face an annular recessed groove 9 of the joint body 1, and rotatably held to the joint body 1 by a holding body 37 engaged with the annular recessed grooves 9, 35. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
