PROBLEM TO BE SOLVED: To provide a drain port filter that can easily maintain a stretch of a net of the drain port filter and that is hardly clogged.SOLUTION: A drain port filter comprises a base seat 3 in which a drain channel 4 is formed in a penetrating manner, and a bag-like elastic net 5 that is held on an undersurface of the base seat by a holding structure 11. The whole circumferential area of an upper end part of the elastic net 5 is held in the state of being folded inward. An elastic return force of the vicinity of the folded part acts in a swelling direction of the elastic net 5.
【課題】排水口フィルターのネットの広がりが維持され易く、目詰まりしづらい排水口フィルターを提供する。【解決手段】排水路４が貫通形成された台座シート３と、台座シートの下面に保持構造１１により保持された袋状の弾性ネット５とを備え、弾性ネット５の上端部位が周方向全域に亘り内側に折り曲げられた状態で保持され、折り曲げた部位近傍の弾性復帰力が、弾性ネット５の膨出方向に働くように構成する。【選択図】図１
