PIPE CONNECTING JOINT DEVICE AND CONNECTING STRUCTURE

PROBLEM TO BE SOLVED: To provide a joint device and a connecting structure capable of sufficiently exhibiting flexibility and water cut-off performance even if a branch pipe is displaced, by preventing the branch pipe from being pushed into a main pipe. SOLUTION: This joint device 1 is provided. The joint device 1 is used for connecting a drilled hole 2A of the main pipe 2 and the branch pipe 3. The joint device 1 has a water cut-off flexible joint 4 and a pipe receiving member 5. The water cut-off flexible joint 4 has a cylindrical part 4A inserting the branch pipe 3 and fixed to an outer peripheral surface of the branch pipe 3, a collar part 4B fixed by externally covering the periphery of the drilled hole 2A of the main pipe 2 and a connecting part 4C connecting these parts. The pipe receiving member 5 has a plurality of supports 5A installed in the drilled hole 2A of the main pipe 2 and a branch pipe receiving base 5B supported by the respective supports 5A and receiving the branch pipe 3 so that at least one of tilting and the sideways movement can be performed.
