DISTRIBUTING JOINT

PROBLEM TO BE SOLVED: To ensure watertight jointing condition between units even if exposed to an easy-to-corrosive environment due to scale generated inside of them, by clamping a section between the units on both ends of a joint provided with a plurality of branched openings formed in parallel from the outside of the unit with a unit fastening means. SOLUTION: A branched opening 12 is provided integrally to a shell part 11 whose one end is closed in a first unit 1, and an annular female type groove 13 is formed at the other end. A branched opening 22 is provided at a shell part 21 whose both ends are opened in a middle unit 2. An annular male protruding part 35 is formed at one end of the shell part 21, and an annular female type groove 23 is formed at the other end respectively. A branched opening 32 is provided integrally at the other end closed shell part 31 in a last unit 3. Respective unit 1, 2 and 3 are arranged in parallel laterally, rubber rings 4 are fitted onto the respective annular female type grooves 13, 23, and respective male protruding part 35 is inserted. A protruding part 512 of a side plate part 511 at one end of a holder is fitted into a recessed part 36 at the end of the last unit 31, and a group of units are fastened with bolts 52.
