PROBLEM TO BE SOLVED: To simplify connection working where a first tubular member and a second tubular member are connected with sealing property secured. SOLUTION: In the tube connection structure 1 of the first tubular member 2 and the second tubular member 3 having an insertion section 7 to be inserted into a pipe line 6 formed in the first tubular member 2, a plurality of first sealing members 4 are provided at the insertion section 7, further, a second sealing member 5 is provided at the root of the insertion section 7 that is an end face of the first tubular member 2. An outer diameter of the first sealing member 4 should be bigger than an internal diameter of the first tubular member 2. In addition, an outer diameter of the second sealing member 5 should be bigger than the outer diameter of the first tubular member 2. COPYRIGHT: (C)2011,JPO&INPIT |
