<p>PROBLEM TO BE SOLVED: To provide a coupling device for a water-intake device of a water purifier, in which an intake for the intake valve of a water purifier is directed vertically downwards while hot-cold water flowing in the coupling device is not leaked. SOLUTION: Female screw sections 113 are formed on one sides of the inner circumferential surfaces of drain pipes 112, 122, and an airtight cover section 114 with an inclined section 114a formed in a tapered shape is formed in the specified sites (sections corresponding to the outer end sections of the drain pipes 112, 122 from one end sections of the female screw sections 113). A male screw section 135a screwed to the female screw sections 113 are formed on one side in a clamping section 135 connected to the drain pipes 112, 122, and a packing member 136 is inserted on the other side at a regular interval.</p> |
