<p>PROBLEM TO BE SOLVED: To provide a simple pipe connecting structure, which can surely connect pipes mechanically and fluidly in a relatively small space with good position decision accuracy, and in which seal material thereof has wide selectivity and seal mechanism thereof is not susceptible to be harmed. SOLUTION: This pipe connecting structure comprises: pipe bodies 1, 1' butt-jointed at ends respectively in such a manner that receiving openings 4, 4' having a large diameter, are contiguous from pipe lines 2, 2' and jointed to the ends of the pipe bodies 1, 1', respectively; and cylindrical couplings 5 provided with seal mechanisms 11, which are inserted into the receiving openings 4, 4' of pipe bodies 1, 1' neighboring to each other, and brought into contact with backs of the receiving openings 4, 4' at end faces thereof. Accordingly, pipes can be surely connected mechanically and fluidly in small space with good positioning accuracy and with simple structure, and seal mechanisms 11 are not affected by sharing force so that the seal mechanisms 11 are not susceptible to be harmed.</p> |
