Further, the size of the receiving portion 25d itself is formed sufficiently larger than the size of the inflow port 40. That is, the washing water flowing in from the inflow port 40 is received by the receiving portion 25d.
Then, the washing water received by the receiving portion 25d flows out into the inner tank 22 from the two water guide ports 25g toward the side.

また、図４に示すように、２つの導水口２５ｇはカバー２３と対向する。カバー２３の導水口２５ｇと対向する面には導水口２５ｇへ向けて突出するガイドリブ２３ａが形成される。ガイドリブ２３ａは、導水口２５ｇから吐出される洗浄水を内装タンク２２の内面へ向けて案内することができる。これにより、カバー２３に開口された貫通孔へ洗浄水が向かうことを抑制することができる。 Further, as shown in FIG. 4, the two water inlets 25g face the cover 23. A guide rib 23a projecting toward the water guide port 25 g is formed on the surface of the cover 23 facing the water guide port 25 g. The guide rib 23a can guide the cleaning water discharged from the water guide port 25g toward the inner surface of the interior tank 22. As a result, it is possible to prevent the washing water from flowing to the through hole opened in the cover 23.

上述した本発明の一実施形態における洗浄水タンク装置１８では、受部２５ｄで受けて第１縦壁部２５ｅへ向かう洗浄水が山形のリブ２５ｈに衝突することで、洗浄水の流速を抑制することができる。また、山形であるため、洗浄水の流速を抑制しつつ、例えばリブが縦壁部に対して垂直に形成される場合に比べて、リブにより洗浄水の流れを止めてしまうことを抑制することができる。従って、洗浄水が内装タンク２２外へ飛び出してしまうことを抑制することができる。 In the washing water tank device 18 according to the embodiment of the present invention described above, the washing water received by the receiving portion 25d and directed toward the first vertical wall portion 25e collides with the chevron rib 25h, thereby suppressing the flow velocity of the washing water. be able to. Further, since it has a chevron shape, it is possible to suppress the flow velocity of the washing water and to prevent the ribs from stopping the flow of the washing water as compared with the case where the ribs are formed perpendicular to the vertical wall portion, for example. Can be done. Therefore, it is possible to prevent the washing water from jumping out of the internal tank 22.

また、上述した本発明の一実施形態における洗浄水タンク装置１８では、受部２５ｄで受けて第１縦壁部２５ｅへ向かう洗浄水が複数の山形のリブ２５ｈに衝突することで、洗浄水の流速をより確実に抑制することができる。また、山形であるため、洗浄水の流速を抑制しつつ、例えばリブが縦壁部に対して垂直に形成される場合に比べて、リブにより洗浄水の流れを止めてしまうことを抑制することができる。従って、洗浄水が内装タンク２２外へ飛び出してしまうことをより確実に抑制することができる。 Further, in the washing water tank device 18 according to the embodiment of the present invention described above, the washing water received by the receiving portion 25d and directed toward the first vertical wall portion 25e collides with the plurality of chevron ribs 25h, so that the washing water is washed. The flow velocity can be suppressed more reliably. Further, since it has a chevron shape, it is possible to suppress the flow velocity of the washing water and to prevent the ribs from stopping the flow of the washing water as compared with the case where the ribs are formed perpendicular to the vertical wall portion, for example. Can be done. Therefore, it is possible to more reliably prevent the washing water from jumping out of the internal tank 22.

また、上述した本発明の一実施形態における洗浄水タンク装置１８では、受部２５ｄの中央に向けて突出する突出壁面２５ｊにより、受部２５ｄで受けた洗浄水を前後方向へと分散させることができる。さらに、分散した先に導水口２５ｇが夫々設けられている。そのため、受部２５ｄで受けた洗浄水同士が合流して水勢が高まることを抑制することができる。従って、洗浄水が内装タンク２２外へ飛び出してしまうことをより確実に抑制することができる。 Further, in the washing water tank device 18 according to the embodiment of the present invention described above, the washing water received by the receiving portion 25d can be dispersed in the front-rear direction by the protruding wall surface 25j protruding toward the center of the receiving portion 25d. it can. Further, 25 g of water guides are provided at the dispersed destinations, respectively. Therefore, it is possible to prevent the washing water received by the receiving portion 25d from merging with each other and increasing the water force. Therefore, it is possible to more reliably prevent the washing water from jumping out of the internal tank 22.
