To provide a partition wall attachment device that can be attached to a partition wall from outside.SOLUTION: A partition wall attachment device of the present invention includes a flexible flange 22 made of elastomer, which protrudes sideward from a device body 11 extending along a central axis of a through-hole 91. When the partition wall attachment device is inserted into the through-hole 91 from a one-end side in an axial direction, the flexible flange 22 passes through the through-hole 91 by becoming a first state in which the flexible flange falls down to the other-end side in the axial direction due to abutting on an open edge of the through-hole 91 and consequently narrows; conversely, when the partition wall attachment device is pulled back in a direction opposite to the insertion of the device, the flexible flange is press-fitted into the through-hole 91 by becoming a second state in which the flexible flange falls down toward the one-end side in the axial direction due to abutting on the open edge of the through-hole 91 and is narrowed and an outer diameter is larger than that in the first state.SELECTED DRAWING: Figure 6
【課題】隔壁に対して外部側から取り付けることが可能な隔壁装着機器を提供する。【解決手段】本発明の隔壁装着機器は、貫通孔91の中心軸に沿って延びる機器本体11から側方に張り出すエラストマー製の可撓フランジ22を備える。その可撓フランジ22は、隔壁装着機器が軸方向の一端側から貫通孔91に挿入されたときには、貫通孔91の開口縁との当接により軸方向の他端側に倒れて窄まる第1状態になって貫通孔91を通過する一方、隔壁装着機器が挿入とは逆方向に引き戻されたときには、貫通孔91の開口縁との当接により軸方向の一端側に倒れて窄まり第1状態より外径が大きな第2状態になって貫通孔91に圧入される。【選択図】図6
