摘要:
To provide a faucet which has taken measures against dust clogging in a valve body.SOLUTION: A faucet 2 includes: a valve body 11 formed into a cylindrical shape in which an axial line C is along a vertical direction; a plurality of first protrusion parts 21 disposed around the axis line of the valve body, protruding toward the axis line from an inner peripheral surface of the valve body, and extending along the vertical direction; second protrusion parts 23 disposed so as to protrude toward the axis line from an edge part opposing to the axis line of a lower end part in the first protrusion part, and formed in such a manner that a distance with the axis line is shorter than a distance Dbetween the lower end of the first protrusion part and the axis line; a lid part 36 which is mounted at an upper part of the valve body, which covers an opening of the valve body, and in which a through-hole 36a communicating with an internal space 11a of the valve body is formed; and a valve element 46 disposed so as to be surrounded by the plurality of first protrusion parts in the valve body, and vertically movable with respect to the plurality of first protrusion parts. A distance Dbetween an upper end of the first protrusion parts and the axis line is longer than the distance between the lower end of the first protrusion part and the axis line.SELECTED DRAWING: Figure 3【課題】弁本体内にゴミが詰まることへの対策を施した給水栓を提供する。【解決手段】給水栓2は、軸線Cが上下方向に沿う筒状に形成された弁本体11と、弁本体の軸線周りに複数配設され、弁本体の内周面から軸線に向かって突出し、かつ上下方向に沿って延びる第1突出部21と、第1突出部における下端部の軸線に対向する縁部から、軸線に向かって突出するように配設され、第1突出部の下端と軸線との距離D2よりも軸線との距離が近くなるように形成された第2突出部23と、弁本体の上方に取付けられ、弁本体の開口を覆い、かつ弁本体の内部空間11aに連通する貫通孔36aが形成された蓋部36と、弁本体内において複数の第1突出部に囲まれるように配設され、複数の第1突出部に対して上下方向に移動可能な弁体46と、を備え、第1突出部の上端と軸線との距離D1は、第1突出部の下端と軸線との距離よりも長い。【選択図】図3
