CONNECTING STRUCTURE OF FLOW PASSAGE FORMING MEMBER

To provide a connecting structure of a flow passage forming member which can prevent the intrusion of water.SOLUTION: A second connecting part 34 has an elastic cylindrical shape which is insertable into a downwardly-opened cylindrical first connecting part 19 from below. Pressed parts 44 in at least three points are separated from one another on an internal peripheral face of the second connecting part 34 so as to surround an inside center 34a of the second connecting part 34. A plurality of elastic support members 45 extend to the inside of the second connecting part 34 from the pressed parts 44 in at least three points. A plurality of the elastic support members 45 are elastically deformed by the insertion of the second connecting part 34 into the first connecting part 19, and press the second connecting part 34 to the internal peripheral face of the first connecting part 19 via the pressed parts 44.SELECTED DRAWING: Figure 5 【課題】水の浸入を防止することが可能な流路形成部材の接続構造の提供。【解決手段】第２接続部３４は、下方へ開口する筒形状の第１接続部１９の内側に下方から嵌入可能な弾性筒形状である。少なくとも３箇所の被押圧部４４は、第２接続部３４の内側中央３４ａを囲むように第２接続部３４の内周面上で互いに離間する。複数の弾性支持部材４５は、少なくとも３箇所の被押圧部４４から第２接続部３４の内側へ延びる。複数の弾性支持部材４５は、第２接続部３４が第１接続部１９の内側に嵌入されて径方向内側へ押圧されることにより弾性変形し、被押圧部４４を介して第２接続部３４を第１接続部１９の内周面に押し付ける。【選択図】図５
