Description

本発明は、排水口を開閉可能な排水栓装置に関し、特に、目皿の掃除を容易にすることができる排水栓装置に関する。   The present invention relates to a drain plug device that can open and close a drain port, and more particularly, to a drain plug device that can facilitate cleaning of an eye plate.

洗面槽や浴槽等のように水を貯留する貯留槽の底部に設けられる排水口には、この排水口を開閉可能にするために排水栓装置１００が設けられている。従来の排水栓装置１００は、例えば図６に示すように、排水口を閉塞する弁１０１を設けた栓蓋１０２と、この栓蓋１０２を支持する支持軸１０３と、毛髪、コンタクトレンズ等の排水口から流下する排水とともに流れる異物を捕捉する目皿１０４、１０５と、を備えており、図示しないが、支持軸１０３の下端に設けられるポップアップ機構により、栓蓋を上下に移動することによって、排水口を開閉することができる（例えば特許文献１)。   A drain plug device 100 is provided at a drain outlet provided at the bottom of a storage tank that stores water, such as a wash basin or a bathtub, so that the drain outlet can be opened and closed. For example, as shown in FIG. 6, a conventional drain plug device 100 includes a plug lid 102 provided with a valve 101 that closes a drain port, a support shaft 103 that supports the plug lid 102, and drainage of hair, contact lenses, and the like. Although not shown in the figure, a pop-up mechanism provided at the lower end of the support shaft 103 moves the stopper lid up and down to move the drainage. The mouth can be opened and closed (for example, Patent Document 1).

この排水栓装置１００においては、目皿１０４、１０５は上下に２つ設けられており、上目皿１０４が排水口から流下する排水の中の異物を捕捉するとともに、下目皿１０５がオーバーフロー流路を通過した排水の中の異物を捕捉する役割を果たす。これらの目皿１０４、１０５は、製造過程での加工の容易さから支持軸１０３に対して回転自在に取付けられることが多い。   In this drain plug device 100, two eye plates 104 and 105 are provided on the upper and lower sides, and the upper eye plate 104 captures foreign matter in the drainage flowing down from the drain port, and the lower eye plate 105 is overflowed. It plays a role in capturing foreign matter in the wastewater that has passed through the road. In many cases, these eye plates 104 and 105 are rotatably attached to the support shaft 103 for ease of processing in the manufacturing process.

特開平１１−６１９３１JP-A-11-61931

しかし、上述のような排水栓装置１００においては、目皿１０４、１０５が支持軸１０３に対して回転自在であるので、この目皿１０４、１０５を例えばブラシでこすって掃除する際に、ブラシの摺動に合わせて目皿１０４、１０５が回転し目皿１０４、１０５に付着した汚れを取り除くことが困難である問題があった。   However, in the drain plug device 100 as described above, since the eye plates 104 and 105 are rotatable with respect to the support shaft 103, when the eye plates 104 and 105 are rubbed and cleaned, for example, with a brush, There is a problem that it is difficult to remove dirt adhered to the eye plates 104 and 105 by rotating the eye plates 104 and 105 in accordance with the sliding.

そこで、本発明は、簡単に目皿を掃除することができる排水栓装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a drain plug device that can easily clean the eye plate.

上記の目的を達成するために、請求項１に記載の排水栓装置は、排水口を開閉可能な排水栓と、一端が前記排水栓の下面に固定される長手状の軸部と、当該軸部に回転自在に取付けられ、排水口を通って流下する排水中の異物を収集する目皿と、前記目皿の下方に設けられ前記軸部にスライド自在に取付けられる回転止めと、を備え、前記回転止めはその上部に、前記目皿の下部に設けられた嵌合部に噛み合い、回転を規制する被嵌合部を有することを特徴としている。   In order to achieve the above object, a drain plug device according to claim 1 includes a drain plug capable of opening and closing a drain port, a longitudinal shaft portion whose one end is fixed to a lower surface of the drain plug, and the shaft. A pan that is rotatably attached to the part and collects foreign matter in the drainage flowing down through the drain port, and a rotation stopper that is provided below the pan and is slidably attached to the shaft part. The rotation stopper has a fitted portion that engages with a fitting portion provided at a lower portion of the eye plate and restricts rotation at an upper portion thereof.

なお、本発明において、「上方」及び「下方」は、排水栓装置を排水口に取付けた状態で、流下する排水の上流側を「上方」といい、下硫側を「下方」という。また、本発明において「回転を規制する」とは、回転止めそのものが軸部に対して回転しないように形成されることにより目皿の回転を規制するもの、及び回転止めそのものは軸部に対して回転自在に構成されており排水栓装置を掃除する際に掃除作業者が回転止めを回転しないように把持することにより目皿の回転を規制するものを含む。   In the present invention, the terms “upper” and “lower” refer to the upstream side of the drained water flowing down in the state where the drain plug device is attached to the drain port, and the lower side as the “lower” side. Further, in the present invention, “restricting rotation” means that the rotation stopper itself is formed so as not to rotate with respect to the shaft portion, so that the rotation of the eye plate is restricted, and the rotation stopper itself is against the shaft portion. It is configured to be freely rotatable, and includes one that restricts the rotation of the eye plate by gripping the rotation stopper so that it does not rotate when cleaning the drain plug device.

また、請求項２に記載の排水栓装置は、前記嵌合部及び被嵌合部は、互いに噛み合う山型であることを特徴としている。   Further, the drain plug device according to claim 2 is characterized in that the fitting portion and the fitted portion are mountain-shaped to mesh with each other.

請求項３に記載の排水栓装置は、所定の操作部と、該操作部からの操作を伝達する伝達部と、該伝達部に伝達された操作により前記軸部の下端を押し上げるポップアップ機構と、をさらに備えることを特徴としている。   The drain plug device according to claim 3, a predetermined operation unit, a transmission unit that transmits an operation from the operation unit, a pop-up mechanism that pushes up a lower end of the shaft unit by the operation transmitted to the transmission unit, Is further provided.

請求項４に記載の排水栓装置は、前記目皿は、前記軸部に外挿する上筒部と、当該上筒部から外側に広がって形成され、排水口を流下する排水に含まれる異物を濾し取る上捕捉部と、を有し、前記上筒部は前記上捕捉部の中央よりも盛り上がって形成されることを特徴としている。   The drain plug device according to claim 4, wherein the eye plate is formed with an upper cylinder portion extrapolated to the shaft portion, and a foreign substance included in the drainage formed to extend outward from the upper cylinder portion and flowing down the drain port. And an upper capturing part that filters out the upper capturing part, wherein the upper cylinder part is formed so as to be raised from the center of the upper capturing part.

請求項５に記載の排水栓装置は、前記排水栓は前記軸部の一端から取外し可能であることを特徴としている。   The drain plug device according to claim 5 is characterized in that the drain plug is removable from one end of the shaft portion.

請求項６に記載の排水栓装置は、前記回転止めは、前記軸部に外挿する下筒部を有し、該下筒部は、前記回転止めの中央において、外側に広がる略円錐状に形成されることを特徴としている。   The drain plug device according to claim 6, wherein the rotation stopper has a lower cylinder portion that is extrapolated to the shaft portion, and the lower cylinder portion has a substantially conical shape that spreads outward at the center of the rotation stopper. It is characterized by being formed.

請求項１に記載の排水栓装置によると、目皿を掃除する際に、回転止めを上方に目皿に当接するようにスライドさせると目皿の下部に設けられた嵌合部と回転止めの被嵌合部とが噛み合うので、目皿が軸部に対して回転することを止めることができる。したがって、回転止めを上方にスライドさせることによって目皿を固定させることができ、たとえば目皿をブラシ等でこすって掃除する際に、ブラシの摺動に合わせて目皿が動くことを防ぐことができ清掃作業を容易なものとすることができる。   According to the drain plug device of the first aspect, when the eye plate is cleaned, when the anti-rotation is slid upward so as to contact the eye plate, the fitting portion provided at the lower part of the eye plate and the anti-rotation device Since the fitted portion meshes with the fitting portion, the eye plate can be prevented from rotating with respect to the shaft portion. Therefore, the eye plate can be fixed by sliding the rotation stopper upward. For example, when the eye plate is rubbed with a brush or the like, the eye plate is prevented from moving in accordance with the sliding of the brush. The cleaning work can be facilitated.

請求項２に記載の排水栓装置によると、目皿の嵌合部と回転止めの被嵌合部は、互いに噛み合う山型であるので、直角に角張って設けられた場合に比べて排水が溜まりにくく、水垢等が付きにくい。また、この嵌合部及び被嵌合部を掃除する際にも、直角に角張った場合に比べてブラシの先端が入り込み易く掃除し易い。   According to the drain plug device of claim 2, since the fitting portion of the eye plate and the fitted portion of the rotation stopper are in a mountain shape that meshes with each other, the drainage is accumulated as compared with a case where the fitting portion is provided to be squared at right angles. It is hard to get water scales. Further, when cleaning the fitting portion and the fitted portion, the tip of the brush is easy to enter and easy to clean as compared with the case where it is squared at right angles.

請求項３に記載の排水栓装置によると、排水栓を軸部が支持することで、遠隔操作により開閉可能なポップアップ式の排水栓装置として用いることができる。   According to the drain plug device of the third aspect, the shaft portion supports the drain plug so that the drain plug device can be used as a pop-up drain plug device that can be opened and closed by remote operation.

請求項４に記載の排水栓装置によると、目皿に形成された上筒部が上捕捉部の中央よりも盛り上がって形成されているので、排水口から流下した排水はのうち上筒部に当った排水がスムーズに上捕捉部に流れ落ちることになる。したがって、上筒部の上端が上捕捉部の中央部分と同じ面上にある場合に比べて、毛髪等の異物がこの上筒部及び軸部に絡まる虞を少なくすることができる。   According to the drain plug device of the fourth aspect, since the upper cylinder part formed on the eye plate is formed so as to rise from the center of the upper capturing part, the drainage flowing down from the drain outlet is in the upper cylinder part. The drained water will smoothly flow down to the upper catching part. Therefore, compared with the case where the upper end of the upper cylinder part is on the same surface as the central part of the upper capturing part, it is possible to reduce the possibility that foreign matters such as hair get entangled with the upper cylinder part and the shaft part.

請求項５に記載の排水栓装置によると、軸部の上端に取付けられた排水栓が軸部から取外し可能であるので、排水栓装置を掃除する際にこの排水栓を取り外すことで、目皿の上捕捉部に収集された異物をより簡単に廃棄することができる。特に請求項４の発明と組み合わせた場合は、毛髪等の異物が上筒部及び軸部に絡まることが少ないので、排水栓を取り外した排水栓装置を排水口から取り外して、下向きに傾けることにより、目皿の上捕捉部に溜まった異物をきわめて簡単に捨てることができる。   According to the drain plug device of claim 5, since the drain plug attached to the upper end of the shaft portion can be removed from the shaft portion, by removing the drain plug when cleaning the drain plug device, The foreign matter collected in the upper trapping part can be discarded more easily. In particular, when combined with the invention of claim 4, foreign matter such as hair is rarely entangled with the upper tube portion and the shaft portion, so the drain plug device from which the drain plug has been removed is removed from the drain port and tilted downward. The foreign matter accumulated on the catching portion on the eye plate can be discarded very easily.

請求項６に記載の排水栓装置によると、下筒部は回転止めの中央において外側に広がる略円錐状に形成されているので、この下筒部の下側の軸部は排水に接触しにくい。したがって、排水栓装置を掃除する際に、この下筒部の下側の軸部を把持することで、比較的手を汚すことなく、排水栓装置を掃除することができる。なお、この下筒部の下側の軸部を把持しやすい形状に形成することや軸部の周りに把持しやすい材質のグリップを設けてもよい。   According to the drain plug device of the sixth aspect, since the lower cylinder portion is formed in a substantially conical shape that spreads outward at the center of the rotation stopper, the lower shaft portion of the lower cylinder portion is unlikely to contact the drainage. . Therefore, when the drain plug device is cleaned, the drain plug device can be cleaned without relatively dirtying the hand by gripping the lower shaft portion of the lower cylinder portion. In addition, you may form in the shape which is easy to hold | grip the lower shaft part of this lower cylinder part, and may provide the grip of the material which is easy to hold around the shaft part.

以下において、本発明の排水栓装置１の最良の実施形態について、各図を参照しつつ説明する。排水栓装置１は、図１に示すように、洗面槽や浴槽などの水を貯留する貯留槽２の底面に設けられた排水口３から排水管４内に挿入されて固定され、排水口３を開状態と閉状態とにそれぞれ維持するものである。この排水栓装置１は、排水口３を開閉する排水栓５と、この排水栓５に上端が固定される軸部６と、この軸部６にスライド自在且つ回転自在に取付けられる目皿７及び回転止め８と、軸部６に外挿されて目皿７が所定以上、上方にスライドすることを規制するゴムパッキン９と、軸部の下端に設けられたグリップ１０に当接して、このグリップを押し上げ可能なポップアップ機構１１と、このポップアップ機構を操作する操作部１２及び操作部１２の操作をポップアップ機構１１に伝達するレリースワイヤ１３とにより構成されている。   Hereinafter, the best embodiment of the drain plug device 1 of the present invention will be described with reference to the drawings. As shown in FIG. 1, the drain plug device 1 is inserted into a drain pipe 4 from a drain port 3 provided on the bottom surface of a storage tank 2 for storing water such as a wash basin or a bathtub, and is fixed. Are maintained in an open state and a closed state, respectively. The drain plug device 1 includes a drain plug 5 that opens and closes a drain port 3, a shaft portion 6 whose upper end is fixed to the drain plug 5, a pan 7 that is slidably and rotatably attached to the shaft portion 6, and This grip comes into contact with a rotation stopper 8, a rubber packing 9 that is extrapolated to the shaft portion 6 and restricts the eyeplate 7 from sliding upward by a predetermined amount, and a grip 10 provided at the lower end of the shaft portion. Is constituted by a pop-up mechanism 11 that can push up, an operation unit 12 that operates the pop-up mechanism, and a release wire 13 that transmits the operation of the operation unit 12 to the pop-up mechanism 11.

排水栓５は排水口３を上方から覆う栓蓋１４と、この栓蓋１４の下端に設けられて、排水口３を排水栓５で閉じたときに排水口３の内周縁に水密よく当接する排水弁１５と、により構成されている。排水口３は例えば陶器で形成された貯留槽２の底面に円形の開口を設け、この開口に例えばステンレス製環状の開口金具１６を取付けたものである。この開口金具１６の外周径は、栓蓋１４の径とほぼ等しく形成されており、排水栓５を閉じた時に排水栓１４によって覆われることで、開口金具１６は外側に露出されなくなり、貯留槽２の意匠性を優れたものにすることができる。   The drain plug 5 is provided at the lower end of the plug lid 14 that covers the drain port 3 from above, and contacts the inner periphery of the drain port 3 in a watertight manner when the drain port 3 is closed by the drain plug 5. And a drain valve 15. The drain port 3 is formed by providing a circular opening on the bottom surface of the storage tank 2 made of, for example, pottery, and attaching a stainless steel annular opening fitting 16 to the opening. The outer peripheral diameter of the opening fitting 16 is formed to be substantially equal to the diameter of the stopper lid 14, and the opening fitting 16 is not exposed to the outside by being covered with the drain plug 14 when the drain plug 5 is closed. The design property of 2 can be made excellent.

目皿７は、図２に示すように、軸部６に外挿する上筒部１７と、この上筒部１７から外側に広がって形成される排水口３を流下する排水に含まれる異物を濾し取る上捕捉部１８と、を有する。上筒部１７は、その上面が上捕捉部１８の中央から盛り上がった形状に形成されており、その中央には軸部６を挿入する貫通孔１９が設けられている。そして、この上筒部１７の下面には、回転止め８の上端に形成される被嵌合部２１に嵌合するなだらかな山型の嵌合部２０が形成されている。   As shown in FIG. 2, the eye plate 7 is configured to remove foreign substances contained in drainage flowing down the upper cylinder part 17 that is extrapolated to the shaft part 6 and the drainage port 3 that is formed to spread outward from the upper cylinder part 17. And an upper capturing portion 18 for filtering. The upper cylinder part 17 has an upper surface formed in a shape rising from the center of the upper capturing part 18, and a through hole 19 into which the shaft part 6 is inserted is provided at the center. Further, on the lower surface of the upper cylindrical portion 17, a gentle chevron-shaped fitting portion 20 that fits into the fitted portion 21 formed at the upper end of the rotation stopper 8 is formed.

回転止め８は、図３に示すように、軸部６に外挿する下筒部２２と、この下筒部２２から外側に広がって形成される目皿７の上捕捉部１８を通過した排水及び貯留槽２の側面に開口した図示しないオーバーフロー孔からオーバーフロー管２３を通って排水管４に流下する排水に含まれる異物を濾し取る下捕捉部２４と、を有しており、下筒部２２はこの下捕捉部２４の中央において、外側に広がる略円錐状に形成される。なお、本実施形態においては、このように回転止め８が下捕捉部２４を有してオーバーフロー排水に含まれる異物を濾し取る役割を兼ねているが、回転止め８がこのような下捕捉部２４を設けない構成としてもよい。   As shown in FIG. 3, the rotation stopper 8 includes a lower cylinder portion 22 that is extrapolated to the shaft portion 6, and drainage that has passed through the upper catching portion 18 of the eye plate 7 that is formed to spread outward from the lower cylinder portion 22. And a lower catching part 24 that filters out foreign matters contained in drainage flowing down from the overflow hole (not shown) opened in the side surface of the storage tank 2 to the drainage pipe 4 through the overflow pipe 23, and the lower cylinder part 22. Is formed in a substantially conical shape extending outward in the center of the lower capturing portion 24. In the present embodiment, the rotation stopper 8 has the lower catching portion 24 as described above, and also serves to filter out foreign matters contained in the overflow drainage. It is good also as a structure which does not provide.

下筒部２２が略円錐状に形成されることで、上方から流下する排水はこの下筒部２２ににより排水管４内でやや外側に導かれるので、排水管４の中心にはあまり排水が流れない。したがって、軸部６の下端に設けられたグリップには排水が付着することが比較的少なく、水垢等の汚れが付きにくい。この下筒部の上端には目皿７の上筒部１７の下面に形成される嵌合部２０に嵌合する被嵌合部２１が設けられている。   Since the lower cylinder part 22 is formed in a substantially conical shape, the drainage flowing down from above is led to the outside slightly in the drain pipe 4 by the lower cylinder part 22, so that there is not much drainage in the center of the drain pipe 4. Not flowing. Accordingly, the grip provided at the lower end of the shaft portion 6 is relatively less likely to have drainage and is less likely to get dirt such as scale. At the upper end of the lower cylinder part, a fitted part 21 to be fitted into a fitting part 20 formed on the lower surface of the upper cylinder part 17 of the eye plate 7 is provided.

ポップアップ機構１１は軸部６のグリップ１０の下側に設けられており、例えばスラストロック機構により構成されている。操作部１２は例えば貯水槽の上端に設けられた図示しない蛇口に隣接して設けられており、排水口３が閉塞した状態で、操作部１２を１回押し込むとその動作がレリースワイヤ１３によりポップアップ機構１１に伝達されて、ポップアップ機構１１の上部に設けられた押し上げ部２５を上方に移動させる。そして、この押し上げ部２５がその上面に当接するグリップ１０を押し上げ、軸部６を介して排水栓５を押し上げ排水口３を開く。排水口３が開いた状態で操作部１２を再度押し込むと、レリースワイヤ１３を介してポップアップ機構１１に伝達され、押し上げ部２５を下方に移動させる。そして、押し上げ部２５に当接しているグリップ１０も下方に降下し、排水栓５が排水口３を閉塞する。なお、ポップアップ機構１１は上述のものに限定されるものではなく、操作部１２の操作により排水口３を開閉することができる様々なポップアップ機構を用いることができる。   The pop-up mechanism 11 is provided on the lower side of the grip 10 of the shaft portion 6, and is constituted by, for example, a thrust lock mechanism. The operation unit 12 is provided, for example, adjacent to a faucet (not shown) provided at the upper end of the water storage tank. When the operation unit 12 is pushed once with the drain port 3 closed, the operation pops up by the release wire 13. The push-up portion 25 provided on the upper portion of the pop-up mechanism 11 is moved upward by being transmitted to the mechanism 11. Then, the push-up portion 25 pushes up the grip 10 in contact with the upper surface, pushes up the drain plug 5 through the shaft portion 6 and opens the drain port 3. When the operation unit 12 is pushed in again with the drain port 3 open, the operation unit 12 is transmitted to the pop-up mechanism 11 via the release wire 13 to move the push-up unit 25 downward. Then, the grip 10 in contact with the push-up portion 25 is also lowered, and the drain plug 5 closes the drain port 3. The pop-up mechanism 11 is not limited to the above-described one, and various pop-up mechanisms that can open and close the drain port 3 by operating the operation unit 12 can be used.

以上のように構成される排水栓装置１を排水管４から取り外して掃除する場合には、排水栓５を把持して排水口３から排水栓装置１を抜き出す。そして、図４に示すように、回転止め８を上方にスライドさせて、回転止め８の被嵌合部２１と目皿７の嵌合部２０とを嵌合させた状態で、さらに回転止め８及び目皿７を上方にスライドさせて、目皿７の上筒部１７の上面をゴムパッキン９に当接させる。このとき、掃除作業をする者は、グリップ１０を把持しつつ、回転止め８を上方にスライドさせるので、もっとも汚れが付着しやすい目皿７に触る必要がない。また、目皿７の嵌合部２０が回転止め８の被嵌合部２１と当接することで、目皿７が軸部６に対して回転することを規制でき、また、目皿７が回転止め８とゴムパッキン９との間に挟みこまれることで、軸部６に対してスライドすることを規制できるので、目皿７をブラシ等でこすって掃除する際に目皿７が回転し、又は上下にスライドすることがなく、より簡単に掃除することができる。   When the drain plug device 1 configured as described above is removed from the drain pipe 4 and cleaned, the drain plug 5 is grasped and the drain plug device 1 is extracted from the drain port 3. Then, as shown in FIG. 4, the rotation stopper 8 is further slid in the upward direction so that the fitted portion 21 of the rotation stopper 8 and the fitting portion 20 of the eye plate 7 are fitted. Then, the eye plate 7 is slid upward, and the upper surface of the upper cylindrical portion 17 of the eye plate 7 is brought into contact with the rubber packing 9. At this time, since the person who performs the cleaning operation slides the rotation stopper 8 upward while holding the grip 10, it is not necessary to touch the eye plate 7 to which dirt is most likely to adhere. Further, the fitting portion 20 of the eye plate 7 abuts on the fitted portion 21 of the rotation stopper 8 so that the eye plate 7 can be prevented from rotating with respect to the shaft portion 6, and the eye plate 7 is rotated. By being sandwiched between the stopper 8 and the rubber packing 9, it is possible to regulate sliding with respect to the shaft portion 6, so that when the eye plate 7 is rubbed and cleaned with a brush or the like, the eye plate 7 rotates, Or it can be cleaned more easily without sliding up and down.

なお、図５（Ａ）に示すように、排水栓５は軸部６と螺着により固定されており、回転させることにより軸部６から排水栓５を取り外すことができる。したがって、排水栓５を取り外した状態で目皿７を掃除することができるので、排水栓５が邪魔になって目皿の内側が掃除しにくくなることが無い。特に、この実施形態の排水栓装置１において目皿７は、リブを交差させて網目状に形成した底部を有する円筒状のものではなく、略半球形状であって球面に開口を設けて上捕捉部とするものであるので、目皿７の表面には余計な凹凸や、エッジ、角となる部分がなく、毛髪等の異物が絡まりにくい。また、半球形状であることで、従来の排水栓装置の円筒状の目皿のように角の隅に異物が留まるといったこともない。また、目皿７の上筒部１７は上捕捉部から盛り上がって円錐状に形成されているので、毛髪等の異物がほどけながら軸部６から上筒部１７上を降下し、軸部６や上筒部１７に絡まりにくい。このようにして、毛髪等の異物は、上捕捉部１８に絡まったり、こびりついたりすることなく捕捉されているので、図５（Ｂ）に示すように、排水栓５を軸部６から取り外した状態で、排水栓装置１の軸部６を斜めに傾けて目皿７の上部を下に向けるか、多少の勢いを付けて振ると、そのまま上捕捉部１８に溜まった異物を極めて簡単に捨てることができる。   As shown in FIG. 5A, the drain plug 5 is fixed to the shaft portion 6 by screwing, and the drain plug 5 can be removed from the shaft portion 6 by rotating. Therefore, the eye plate 7 can be cleaned with the drain plug 5 removed, so that the drain plug 5 does not get in the way and the inside of the eye plate is not easily cleaned. In particular, in the drain plug device 1 of this embodiment, the eye plate 7 is not a cylindrical shape having a bottom formed by meshing ribs, but is substantially hemispherical and has an opening in a spherical surface so as to capture the top. Therefore, the surface of the eye plate 7 does not have extra irregularities, edges, or corners, and foreign objects such as hair are less likely to get tangled. Further, the hemispherical shape prevents foreign matter from staying at the corners unlike the cylindrical eye plate of the conventional drain plug device. Further, since the upper cylindrical portion 17 of the eye plate 7 rises from the upper capturing portion and is formed in a conical shape, the upper cylindrical portion 17 is lowered from the shaft portion 6 while the foreign matter such as hair is unwound, and the shaft portion 6 or It is difficult to get entangled with the upper tube portion 17. In this way, foreign matters such as hair are captured without being entangled with or stuck to the upper capturing portion 18, so that the drain plug 5 is removed from the shaft portion 6 as shown in FIG.
