JOINT MAIN BODY DEVICE FOR PIPE JOINT, AND JOINT ANNULAR MEMBER TO BE USED FOR JOINT MAIN BODY DEVICE

摘要

PROBLEM TO BE SOLVED: To appropriately, excellently and effectively absorb the vibration to be transmitted to a pipe joint device during the use.

SOLUTION: This joint main body device has a first main body member 11 formed with a fitting part 12 or a connection fitting part 81 on one end side thereof and provided with a first joint means 15 in a first joint end surface 14 on the other end side thereof and formed with a first inside flow passage 16 passing through the inside thereof in the axial direction, and a second main body member 31 formed with parts 33 and 34 to be connected on one end side thereof and provided with a second joint means 36 in a second joint end surface 35 on the other end side thereof and formed with a second inside flow passage 37 passing through the inside thereof in the axial direction. The joint end surfaces 14 and 35 including each joint member 15 and 36 are integrally joined with each other by the joint annular member 51 having a required hardness and the vibration absorbing characteristic so that each inside flow passage 16 and 37 of each of the first and the second main body members 11 and 31 communicates with each other.
