PROBLEM TO BE SOLVED: To enable a positive fixing of the thermal extensible or shrinkable pipings to be carried out under such a structure as one in which the pipings can be arranged against a wall surface without showing any clearance.SOLUTION: This invention provides a telescopic joint 10 connected between pipings 3, 3 and used as an absorbing material for thermal extention or shrinkage that has an annular loop shape part 11 for forming a crossing part at an intermediate portion in a longitudinal direction. The first straight line part 14 between the first connecting end part 12 of one of both ends in a longitudinal direction and the loop shape part 11 is provided with a curved bent part K in such a way that pipe cores C1, C2 at each of both connecting ends 12, 13 may be positioned in a plane crossing at a right angle with a loop circle central axis O of the loop shape part 11 as seen from its top plan view. |
