VALVE UNIT
To provide a valve unit capable of persistently reducing slide resistance between a plane part of a primary valve body and a packing member arranged in a secondary valve body.SOLUTION: A valve unit 6 comprises a primary valve body 7 with a plane part 751b, and a secondary valve body 8 connected to the primary valve body 7 so as to slidable with the plane part 751b of the primary valve body 7, and can switch a water discharge state with sliding of the primary valve body 7 or secondary valve body 8. The secondary valve body 8 has: water passage holes 821, 822 through which water can pass from the primary valve body 7; a packing arrangement groove 841 formed around the water passage holes 821, 822; a packing member 85 arranged in the packing arrangement groove 841 and contacting with the primary valve body 7; a grease reservoir 842 filled with grease; and a grease supply groove 843 connecting between the packing arrangement groove 841 and the grease reservoir 842.SELECTED DRAWING: Figure 9
【課題】一次側弁体の平面部と二次側弁体に配置されるパッキン部材との摺動抵抗を持続的に低減できる弁装置を提供すること。【解決手段】平面部７５１ｂを有する一次側弁体７と、一次側弁体７の平面部７５１ｂに摺動可能に一次側弁体７に連結される二次側弁体８と、を備え、一次側弁体７又は二次側弁体８の摺動により吐水状態を切り替え可能な弁装置６であって、二次側弁体８は、一次側弁体７からの水が通水可能な通水孔８２１，８２２と、通水孔８２１，８２２の周囲に形成されるパッキン配置溝８４１と、パッキン配置溝８４１に配置され一次側弁体７に当接するパッキン部材８５と、グリスが充填されるグリス溜まり８４２と、パッキン配置溝８４１とグリス溜まり８４２とを接続するグリス供給溝８４３と、を有する。【選択図】図９
