Claims

[Claims for Utility Model Registration] 1. A first member 1 in which an external threaded portion 8 is provided on the outer surface 7 and a concave peripheral part 10 for a packing is formed in one end surface 9, and a concave peripheral part for a packing in the first member 1. An annular packing 3 fitted into the portion 10 and the first member 1
a second member 2 having a circular protrusion 20 which is fitted into the concave peripheral part 10 for the packing and presses the packing 3; and a fastening member which tightens the first member 1 and the second member 2 in a direction in which they approach each other. 4, the front surface 3a and back surface 3b of the above-mentioned patch 3 are flat surfaces that are parallel to each other or slightly inclined in the radial direction, and from the front surface 3a to the back surface 3b. A pipe joint characterized in that a large number of elastic deformation escape holes 29 are formed therethrough. 2. A first member 1 in which a male threaded portion 8 is provided on the outer surface 7 and a concave peripheral part 10 for a seal is formed in one end surface 9, and an annular member that is fitted into the concave peripheral part 10 for a seal in the first member 1. Packing 3 and the first member 1
a second member 2 having a circular protrusion 20 which is fitted into the concave peripheral part 10 for the packing and presses the packing 3; and a fastening member which tightens the first member 1 and the second member 2 in a direction in which they approach each other. 4, the front surface 3a and back surface 3b of the packing 3 are flat surfaces that are parallel to each other or slightly inclined in the inner and outer radial directions, and the front surface 3a and/or back side 3b
A pipe joint characterized in that a large number of concave portions 30 for escape from elastic deformation are formed in the pipe joint.
