PROBLEM TO BE SOLVED: To provide a connecting structure of tubular member in which the first tubular member and the second tubular member can be connected by only inserting the second tubular member to the first tubular member, and the connection can be released by rotating one side or both sides. SOLUTION: A wedge holder 14 having a taper surface 16 is installed to a first tubular member 10, to hold a wedge 30. When a second tubular member 20 is inserted to the first tubular member 10, the diameter of the wedge 30 is extended, and a male screw 22 is inserted in the wedge 30 as it is. When the second tubular member 20 is going to be removed, taper surfaces 16 and 34 are abutted each other, a female screw on the inner periphery of the wedge 30 bites to the male screw 22, and the removal of the tubular member 20 is blocked. The tubular member 20 can be removed by rotating it. |
