PURPOSE:To surely prevent water leakage by insertedly housing the packing, having a longer axis direction length than that of a packing housing part, to the packing housing part of the bush inside inserted in a box nut. CONSTITUTION:The bush 4 having a packing housing part 41 and a deformed part 42 is inside inserted in a box nut 2, and the packing 5, having a longer axis direction length than that of the part 41, is insertedly housed in the part 41 of the bush 4. This enables the water leakage to be surely prevented since the packing 5 is crushed by the clamping of the nut 2 to expand into the inner part to be pressed to a second pipe body 3. |
