<p>PROBLEM TO BE SOLVED: To provide a rain leader pipe joint capable of absorbing the quake of the ground and being hard to cause damage in a joining part between a rain water drain pipe and a rain leader. SOLUTION: An upstream side socket 12 of a joint body 11 molded out of a flexible material is fittingly connected to the downstream end 5 of the leader 4 of a building 2. A downstream side socket 15 of the joint body 11 is fittingly connected to the upstream end 6 of the rain water drain pipe 7. A bellows 17 is provided to at least a part between the downstream side socket 15 of the joint body 11 and the upstream side socket 12. The joint body 11 is formed in a bendable and expansible manner. The rolling of the building 2 can be absorbed by the bending of the bellows 17. The pitching of the building 2 and ground subsidence can be absorbed by expansion of the bellows 17. Accordingly, the joining part between the rain water drain pipe 7 and the leader 4 is constituted so as to prevent damage.</p> |
