PROBLEM TO BE SOLVED: To provide pipe connection means capable of securing a sufficiently wide space on an outer peripheral part around a branch port and improving operability for arranging a branch pipe or the like on the branch port side.SOLUTION: Pipe connection means 1 includes a base pipe 20 in which a fluid is allowed to flow and a branch port 3 branched from the base pipe 20 to open/close the branch port 3 by an opening/closing mechanism 15. The opening/closing mechanisms 15 includes: a valve body 7 including a valve part 7a having a size capable of closing the branch port 3 and a moving part 7b for moving the valve part 7a and curved along an inner periphery of the base pipe 20; and an operation part 11 for applying driving force to the valve body part 7. The operation part 11 is arranged on the approximately opposite side of the branch port 3 and the operation part 11 moves the valve body part 7 along the inner periphery of the base pipe 20 to open/close the branch port 3. |
