DRAIN VALVE DEVICE, WASHING WATER TANK AND FLUSH TOILET BOWL
PROBLEM TO BE SOLVED: To improve operability and durability.SOLUTION: A drain valve device includes a valve body, a shaft part, a pull-up part, a shaft guide part, a slide surface and a surface to be slid. The valve body is provided above a drain port and opens/closes the drain port. The shaft part extends upward from the valve body. The pull-up part pulls the shaft part upward. The shaft guide part is provided along an axial direction of the shaft part outside of an outside peripheral surface of the shaft part, and guides the movement of the shaft part according to the pull-up operation of the shaft part. The slide surface is provided on the outside peripheral surface of the shaft part, and slides against an inside peripheral surface of the shaft guide part by the movement of the shaft part. The surface to be slid is provided on the inside peripheral surface of the shaft guide part, and allows the slide surface of the shaft part to slide. At least one of the slide surface and the surface to be slid has a shape in which a contact portion between the slide surface and the surface to be slid changes in a fluid manner according to the movement of the shaft part.SELECTED DRAWING: Figure 6C
【課題】操作性および耐久性を向上させること。【解決手段】実施形態に係る排水弁装置は、弁体と、軸部と、引き上げ部と、軸ガイド部と、摺動面と、被摺動面とを備える。弁体は、排水口の上方に設けられ、排水口を開閉する。軸部は、弁体から上方へ延びる。引き上げ部は、軸部を上方へ引き上げる。軸ガイド部は、軸部の外側周面の外側に軸部の軸方向に沿って設けられ、軸部の引き上げ操作に伴う軸部の移動をガイドする。摺動面は、軸部の外側周面に設けられ、軸部の移動によって軸ガイド部の内側周面に対して摺動する。被摺動面は、軸ガイド部の内側周面に設けられ、軸部の摺動面を摺動させる。摺動面および被摺動面の少なくともいずれか一方は、摺動面と被摺動面との接触部分が軸部の移動に伴い流動的に変化する形状を有する。【選択図】図６Ｃ
