CONDUIT CONNECTING STRUCTURE AND WATER SUPPLY DEVICE
To eliminate the wobbling (play) of a connection point, in a conduit connecting structure having a sheath pipe part 1 in which the other conduit end portion is tightly inserted into one conduit end of a connection object, having a lock protrusion 21 at an insertion part 2 of the other conduit end, also having an engagement recessed strip part 11 engaged with the lock protrusion at an internal peripheral face of the sheath pipe part, a seal accommodation recessed strip part 12 accommodating a ring seal 5 at a depth side of the engagement recessed strip part, and a notched part 13 in which the engagement recessed strip part is exposed at an opening end of the sheath pipe part, and the lock protrusion becomes advanceable, making the lock protrusion of the insertion part located on an engagement recessed strip part extension line by inserting the lock protrusion from the notched part, and retained in the connection portion when relatively turning with a pipe axial direction as a center.SOLUTION: A circular plate body 3 abutting on an opening end face of a sheath pipe part, reaching a lock recessed strip part from a notched part, and externally inserted into an insertion part by arranging a sealing tongue piece part 31, and a pressing cylinder body 4 screwed to an external periphery of the insertion part so as to be capable of pressing the circular plate body to a lock protrusion side are arranged at the insertion part of a rear position rather than the lock protrusion.SELECTED DRAWING: Figure 1
【課題】連結対象の一方の管路端に他方の管路端部分が密挿される鞘管部１を設け、他方の管路端の挿入部２に係止突部２１を設け、鞘管部の内周面に係止突部が係合する係合凹条部１１と、係合凹条部の奥方にリングシール５を収納したシール収納凹条部１２と、鞘管部の開口端に係合凹条部が露出して係止突部が進出可能とする切欠部１３とを設けて、挿入部の係止突部を切欠部から差し入れて係合凹条部延長上に位置させて管軸方向を中心とし相対的に回動すると連結部分の抜け止めがなされる管路連結構造において、連結箇所のガタツキ（遊び）をなくする。【解決手段】係止突部より後方位置の挿入部に、鞘管部の開口端面に当接し、切欠部から係止凹条部に至る封止舌片部３１を設けて挿入部に外挿した円板体３と、円板体を係止突部方へ押圧可能に挿入部外周に螺装した押圧筒体４とを設けてなる。【選択図】図１
