SOLUTION: The joint has a union type structure. One side of the joint is connected to a pipe by an adhesive and has a male screw portion on its outer periphery. The other side of the joint is a cap nut equipped with a rubber packing for water cut-off, a slip washer for preventing distortion of the rubber packing and a female screw portion. The joint having the male screw portion on its outer periphery is connected to a pipe so as to perform the water cut-off. COPYRIGHT: (C)2006,JPO&NCIPI
