PROBLEM TO BE SOLVED: To provide a branch device with high respondence performance that can connect various branch pipes, in branch pipe connection work of branch work.SOLUTION: A branch device 2 branches a fluid in a non-cutoff flow state from an opening 1a of a fluid pipe 1 bored in a case body 3 of a division structure externally fitted in a hermetic manner so as to retain a required space S on the outer peripheral surface of the fluid pipe 1, to a branch pipe 20 side through a branch port 5 of the case body 3 by operation of a valve body 6. The branch port 5 is formed by integrating divided case bodies 3 with each other, and the case body 3 has a structure that simultaneously holds a connection pipe 8 to which the branch pipe 20 is connected by the branch port 5. The case body 3 includes the valve body 6 of an arc shape moving in the required space S along a circumferential direction of the fluid pipe 1. The valve body 6 can open/close a flow passage communicating the opening 1a of the fluid pipe 1 with the branch pipe 20 by an operation part 7 provided in the case body 3. |
