PROBLEM TO BE SOLVED: To enable smooth connection and separation of joints and secure durability of the joint.SOLUTION: When first joints 30A and second joints 30B are joined to each other, friction is generated between guide pins 18 and guide holes 28, and a second mounting plate 26 is inclined to a first mounting plate 16. Partial contact occurs. Tips of some press bars 20 come into contact with a facing surface 2602 of the second mounting plate 26, and tips of the other press bar 20 do not come into contact with the facing surface 2602 of the second mounting plate 26. When pressing force of elastic members 22 is applied to the second mounting plate 26 from the press bar 20 in contact with the facing surface 2602 of the second mounting plate 26, the second mounting plate 26 is inclined in a direction to make the facing surface 2602 of the second mounting plate 26 parallel to a facing surface 1602 of the first mounting plate 16. |
