To provide the valve member that does not cause problems such as, in particular, water leakage even if annular packing with a parting line or burr on an inner surface of the valve member is adopted, and that can prevent a storage part from being damaged while giving the annular packing versatility.SOLUTION: The valve member that closes an exhaust port of a tank comprises: a valve body having a substantially plate shape, a storage part opened in a lateral direction, the annular packing that is stored in a storage part and contacts a peripheral edge of the exhaust port and tightly connects the valve body and the exhaust port, and an annular groove that is provided on the side of the storage part, wherein the annular groove is formed in accordance with a position of the parting line of the annular packing.SELECTED DRAWING: Figure 5
【課題】内側面にパーティングラインやバリを生じた環状パッキンを採用しても特に漏水などの問題を生じない、また収納部の破損を防止しつつ環状パッキンに汎用性を持たせることができる弁部材を提案する。【解決手段】槽体の排水口を閉塞する弁部材を、略板状の弁体部と、該弁体部の下方に備えられた、側面方向に開口した収納部と、該収納部内に収納される、排水口周縁に当接して弁体部と排水口の間を水密に接続する環状パッキンと、収納部側面に、環状に設けられた溝部と、からなり、該溝部を環状パッキンのパーティングラインの位置に合わせて形成する。【選択図】図５
