Description

本発明は、ウォッシャタンクに関する。 The present invention relates to a washer tank.

従来から、下記特許文献１に示されるようなウォッシャタンクが知られている。
このウォッシャタンクは、水平方向に分割される一対の椀状部材を有し、天壁部にリブを設けることで、ウォッシャ液が充填されにくくなる空間であるエア溜り部を形成している。これにより、ウォッシャ液が凍結して体積膨張した際に、ウォッシャタンクが破裂するのを抑えている。
しかしながら、このようなウォッシャタンクでは、例えば射出成形により椀状部材を形成する際に、金型のスライド方向の制約により、ウォッシャタンクの水平方向の凹凸形状が限定されやすく、エンジンルーム内でのウォッシャタンクのレイアウト性が悪化するという問題があった。 Conventionally, a washer tank as shown in Patent Document 1 below has been known.
This washer tank has a pair of bowl-shaped members that are divided in the horizontal direction, and by providing ribs on the top wall portion, an air pool portion that is a space in which the washer liquid is difficult to be filled is formed. This prevents the washer tank from exploding when the washer fluid freezes and expands in volume.
However, in such a washer tank, for example, when a bowl-shaped member is formed by injection molding, the horizontal uneven shape of the washer tank is likely to be limited due to restrictions on the sliding direction of the mold, and the washer in the engine room. There was a problem that the layout of the tank deteriorated.

このような問題を解決するために、下記特許文献２に示されるようなウォッシャタンクが知られている。
このウォッシャタンクは、重力方向に分割される一対の椀状部材を有している。これにより、金型のスライド方向による、ウォッシャタンクの水平方向の凹凸形状への制約を少なくし、椀状部材の形状に自由度を与え、エンジンルーム内で隣り合う部材に合わせてウォッシャタンクのレイアウト性を確保している。 In order to solve such a problem, a washer tank as shown in Patent Document 2 below is known.
This washer tank has a pair of bowl-shaped members that are divided in the direction of gravity. This reduces restrictions on the horizontal uneven shape of the washer tank due to the sliding direction of the mold, gives freedom to the shape of the bowl-shaped member, and lays out the washer tank according to the adjacent members in the engine room. The sex is secured.

しかしながら、上記特許文献２に記載のウォッシャタンクでは、天壁部に溶着面が設けられるためリブが設けられておらず、エア溜り部を形成できなかった。よって貯留部内にウォッシャ液が充満してしまい、ウォッシャ液の凍結による体積膨張により、ウォッシャタンクが破裂するおそれがあった。 However, in the washer tank described in Patent Document 2, since a welding surface is provided on the top wall portion, no rib is provided, and an air pool portion cannot be formed. Therefore, the washer fluid is filled in the storage portion, and the washer tank may burst due to the volume expansion due to the freezing of the washer fluid.

本発明は、前述した事情に鑑みてなされたものであって、成形の自由度を向上してウォッシャタンクのレイアウト性を確保しながら、仮に貯留部に充満したウォッシャ液が凍結しても破裂するのを防止することができるウォッシャタンクを提供することを目的とする。 The present invention has been made in view of the above-mentioned circumstances, and while improving the degree of freedom of molding and ensuring the layout of the washer tank, even if the washer liquid filled in the storage portion freezes, it bursts. It is an object of the present invention to provide a washer tank that can prevent the above.

前記課題を解決するために、本発明に係るウォッシャタンクは、水平方向に互いに対向して配置され、ウォッシャ液の貯留部となる閉断面構造を内側に形成する一対の椀状部材を有し、重力方向下部に配置された底壁部と、前記底壁部から重力方向に沿って立ち上がり、前記重力方向と直交する水平方向で対向する２つの側壁部と、前記底壁部の前記重力方向上方に配置され、前記底壁部と前記重力方向で対向する天壁部と、前記側壁部および前記天壁部のいずれか一方に形成され、外部から前記ウォッシャ液を前記貯留部内に流入させる流入孔と、前記側壁部に沿って、前記流入孔と隣り合い、かつ前記２つの側壁部に跨るように設けられたリブと、を備え、前記椀状部材それぞれにおける開口周縁部にはタンク溶着面が形成され、それぞれの前記タンク溶着面同士が、互いに溶着されて接合され、前記リブは、前記貯留部側に向けて突出するように、前記一対の椀状部材に各別に形成され、一対の前記リブ同士は、前記水平方向に互いに対向して配置されるとともに、それぞれの先端部同士が溶着されるリブ溶着面を有し、前記リブ溶着面は、前記タンク溶着面と同一平面上に位置し、前記リブは、前記重力方向に沿って延在し、前記重力方向上方の上辺における全体が、前記天壁部と接合されているとともに、各側辺の全体が、それぞれ前記側壁部に接合されており、前記リブは、基端側に位置し、前記２つの側壁部のうちの少なくともいずれか一方を凹ませた凹部からなる中空部と、先端側に位置する中実部と、を有することを特徴とする。 In order to solve the above problems, the washer tank according to the present invention has a pair of bowl-shaped members that are arranged horizontally facing each other and form a closed cross-sectional structure that serves as a storage portion for the washer fluid. A bottom wall portion arranged in the lower part in the gravity direction, two side wall portions rising from the bottom wall portion along the gravity direction and facing each other in the horizontal direction orthogonal to the gravity direction, and the bottom wall portion above the gravity direction. An inflow hole formed in one of the bottom wall portion, the top wall portion facing the bottom wall portion in the direction of gravity, the side wall portion, and the top wall portion, and allowing the washer fluid to flow into the storage portion from the outside. And a rib provided along the side wall portion so as to be adjacent to the inflow hole and straddle the two side wall portions, and a tank welding surface is provided on the opening peripheral edge portion of each of the bowl-shaped members. The tank welding surfaces are formed and welded to each other and joined to each other, and the ribs are separately formed on the pair of bowl-shaped members so as to project toward the storage portion side, and the pair of the above ribs are formed. The ribs are arranged so as to face each other in the horizontal direction and have a rib welding surface to which their respective tips are welded, and the rib welding surface is located on the same plane as the tank welding surface. The ribs extend along the direction of gravity, and the entire upper side in the direction of gravity is joined to the top wall portion, and the entire side surface is joined to the side wall portion. The rib is located on the proximal end side and has a hollow portion formed by a recess in which at least one of the two side wall portions is recessed, and a solid portion located on the distal end side. It is characterized by.

このように、上記構成では、一対の椀状部材が水平方向に互いに対向して配置されている。このため、ウォッシャタンクの水平方向の凹凸形状に対する成形の自由度を向上し、エンジンルーム内で隣り合う部材に合わせたウォッシャタンクのレイアウト性を確保することができる。
また、一対のリブ同士が溶着されるリブ溶着面同士が、タンク溶着面と同一平面上に位置している。このため、タンク溶着面の溶着作業において、高熱の鉄板をタンク溶着面に当接させた際に、リブ溶着面にも同時に当接させることが可能になる。これにより、縦割タイプのウォッシャタンクであっても、タンク溶着面およびリブ溶着面それぞれにおける溶着作業を、同時に効率的に行うことができる。 As described above, in the above configuration, a pair of bowl-shaped members are arranged so as to face each other in the horizontal direction. Therefore, it is possible to improve the degree of freedom of molding the washer tank with respect to the uneven shape in the horizontal direction, and to secure the layout of the washer tank according to the adjacent members in the engine room.
Further, the rib welding surfaces on which the pair of ribs are welded are located on the same plane as the tank welding surface. Therefore, in the welding work of the tank welding surface, when the high-temperature iron plate is brought into contact with the tank welding surface, it can be brought into contact with the rib welding surface at the same time. As a result, even in the vertically split type washer tank, the welding work on each of the tank welding surface and the rib welding surface can be efficiently performed at the same time.

また、リブが重力方向に沿って延在するとともに、重力方向上方の上辺における全体が、天壁部と接合されているとともに、各側辺の全体が、それぞれ側壁部に接合されている。このため、貯留部のうち、リブを挟んで流入孔と水平方向で反対側に位置する部分に、ウォッシャ液が充填されにくくなる空間であるエア溜り部を形成することができる。これにより、貯留部にウォッシャ液が充満するのを抑制し、貯留部に充満したウォッシャ液が凍結することで、破裂するのを防止することができる。
さらに、リブが先端側に位置する中実部を有している。このため、リブの全体を中空状に形成しないことで、リブの先端が過剰に細くなるのを防ぐことができる。よって、リブの成形を容易にするとともに、リブの先端に形成されるリブ溶着面を大きく形成することで、リブの強度を大きくすることができる。 Further, the ribs extend along the direction of gravity, the entire upper side in the direction of gravity is joined to the top wall portion, and the entire side side is joined to the side wall portion. For this reason, it is possible to form an air reservoir portion, which is a space in which the washer fluid is less likely to be filled, in a portion of the storage portion located on the side opposite to the inflow hole in the horizontal direction across the rib. As a result, it is possible to prevent the reservoir from being filled with the washer fluid, and to prevent the washer fluid filled in the reservoir from freezing and bursting.
Further, the rib has a solid portion located on the tip side. Therefore, by not forming the entire rib in a hollow shape, it is possible to prevent the tip of the rib from becoming excessively thin. Therefore, the strength of the rib can be increased by facilitating the molding of the rib and forming a large rib welding surface formed at the tip of the rib.

また、前記ウォッシャタンクは、前記流入孔に設けられ、前記ウォッシャ液を前記貯留部に供給するホースを備え、前記流入孔は、前記天壁部に形成され、前記リブの前記重力方向の大きさは、前記ホースのうち、前記貯留部内に位置する部分の前記重力方向の大きさよりも大きくてもよい。 Further, the washer tank is provided in the inflow hole and includes a hose for supplying the washer liquid to the storage portion. The inflow hole is formed in the top wall portion and has a size of the rib in the gravity direction. May be larger than the size of the portion of the hose located in the storage portion in the direction of gravity.

この場合には、リブの重力方向の大きさが、ホースのうち、貯留部内に位置する部分の重力方向の大きさよりも大きくなっている。このため、エンジンルーム内のレイアウトによって、貯留部内にホースを配置する空間を大きく確保できない場合であっても、リブにより貯留部内にエア溜りを確実に確保することができる。 In this case, the size of the rib in the direction of gravity is larger than the size of the portion of the hose located in the storage portion in the direction of gravity. Therefore, even if a large space for arranging the hose cannot be secured in the storage portion due to the layout in the engine room, the rib can surely secure the air pool in the storage portion.

また、本発明に係るウォッシャタンクは、水平方向に互いに対向して配置され、ウォッシャ液の貯留部となる閉断面構造を内側に形成する一対の椀状部材を有し、重力方向下部に配置された底壁部と、前記底壁部から重力方向に沿って立ち上がり、前記重力方向と直交する水平方向で対向する２つの側壁部と、前記底壁部の前記重力方向上方に配置され、前記底壁部と前記重力方向で対向する天壁部と、前記側壁部に形成され、外部から前記ウォッシャ液を前記貯留部内に流入させる流入孔と、前記側壁部に沿って、前記流入孔と隣り合い、かつ前記２つの側壁部に跨るように設けられたリブと、を備え、前記椀状部材それぞれにおける開口周縁部にはタンク溶着面が形成され、それぞれの前記タンク溶着面同士が、互いに溶着されて接合され、前記リブは、前記貯留部側に向けて突出するように、前記一対の椀状部材に各別に形成され、一対の前記リブ同士は、前記水平方向に互いに対向して配置されるとともに、それぞれの先端部同士が溶着されるリブ溶着面を有し、前記リブ溶着面は、前記タンク溶着面と同一平面上に位置し、前記リブは、前記流入孔の正面視で、前記流入孔を前記重力方向上方から囲むように、かつ前記重力方向下方が開放されるように配置されているとともに、各側辺の全体がそれぞれ前記側壁部に接合されていることを特徴とする。 Further, the washer tank according to the present invention is arranged so as to face each other in the horizontal direction, has a pair of bowl-shaped members forming a closed cross-sectional structure that serves as a storage portion for the washer fluid, and is arranged in the lower part in the direction of gravity. The bottom wall portion, the two side wall portions that rise from the bottom wall portion in the direction of gravity and face each other in the horizontal direction perpendicular to the gravity direction, and the bottom wall portion that is arranged above the bottom wall portion in the gravity direction. A top wall portion facing the wall portion in the direction of gravity, an inflow hole formed in the side wall portion and allowing the washer fluid to flow into the storage portion from the outside, and an inflow hole adjacent to the inflow hole along the side wall portion. A tank welding surface is formed at the opening peripheral edge of each of the bowl-shaped members, and the tank welding surfaces are welded to each other. The ribs are separately formed on the pair of bowl-shaped members so as to project toward the storage portion side, and the pair of ribs are arranged so as to face each other in the horizontal direction. At the same time, each tip portion has a rib welding surface to which the tips are welded to each other, the rib welding surface is located on the same horizontal surface as the tank welding surface, and the rib is the inflow in front view of the inflow hole. It is characterized in that the hole is arranged so as to surround the hole from above in the direction of gravity and the lower part in the direction of gravity is opened, and the entire side surface is joined to the side wall portion.

また、リブが、流入孔の正面視で、流入孔を重力方向上方から囲むように、かつ重力方向下方が開放されるように配置されているとともに、各側辺の全体がそれぞれ側壁部に接合されている。このため、貯留部のうち、流入孔を囲むリブの外側に位置する部分に、ウォッシャ液が充填されにくくなる空間であるエア溜り部を形成することができる。これにより、貯留部にウォッシャ液が充満するのを抑制し、貯留部に充満したウォッシャ液が凍結することで、破裂するのを防止することができる。 In addition, the ribs are arranged so as to surround the inflow hole from above in the gravity direction and open in the lower part in the gravity direction in front view of the inflow hole, and the entire side of each side is joined to the side wall portion. Has been done. For this reason, it is possible to form an air pool portion, which is a space in which the washer fluid is less likely to be filled, in a portion of the storage portion located outside the rib surrounding the inflow hole. As a result, it is possible to prevent the reservoir from being filled with the washer fluid, and to prevent the washer fluid filled in the reservoir from freezing and bursting.

また、前記リブは、前記流入孔の開口周縁部に沿って、前記流入孔の正面視で、前記流入孔を前記重力方向上方から囲むように配置されてもよい。
この場合には、リブが流入孔の開口周縁部に沿って、流入孔を重力方向上方から囲むように配置されているので、流入孔の開口周縁部とリブとの間に空間が形成されるのを防ぐことができる。これにより、流入孔を囲むリブの外側に形成されるエア溜り部を、可能な限り大きくすることができる。 Further, the rib may be arranged along the peripheral edge of the opening of the inflow hole so as to surround the inflow hole from above in the direction of gravity in front view of the inflow hole.
In this case, since the ribs are arranged along the peripheral edge of the opening of the inflow hole so as to surround the inflow hole from above in the direction of gravity, a space is formed between the peripheral edge of the opening of the inflow hole and the rib. Can be prevented. As a result, the air reservoir formed on the outside of the rib surrounding the inflow hole can be made as large as possible.

また、前記リブは、前記２つの側壁部のうちの少なくともいずれか一方を凹ませることで、前記貯留部側に向けて突出した状態で形成されてもよい。
この場合には、２つの側壁部のうちの少なくともいずれか一方を凹ませることで、リブが形成されているので、側壁部およびリブの厚みを全域にわたって均一にすることができる。これにより、側壁部およびリブが、例えば合成樹脂材料の射出成形等により形成された場合に、側壁部およびリブに、局部的に表面が凹むヒケが生じるのを抑制することができる。 Further, the rib may be formed in a state of protruding toward the storage portion side by denting at least one of the two side wall portions.
In this case, since the rib is formed by denting at least one of the two side wall portions, the thickness of the side wall portion and the rib can be made uniform over the entire area. As a result, when the side wall portion and the rib are formed by, for example, injection molding of a synthetic resin material, it is possible to prevent the side wall portion and the rib from having a sink mark whose surface is locally recessed.

また、前記リブは、基端側に位置し、前記２つの側壁部のうちの少なくともいずれか一方を凹ませた凹部からなる中空部と、先端側に位置する中実部と、を有してもよい。
この場合には、リブが先端側に位置する中実部を有している。このため、リブの全体を中空状に形成しないことで、リブの先端が過剰に細くなるのを防ぐことができる。よって、リブの成形を容易にするとともに、リブの先端に形成されるリブ溶着面を大きく形成することで、リブの強度を大きくすることができる。 Further, the rib has a hollow portion that is located on the proximal end side and is formed by recessing at least one of the two side wall portions, and a solid portion that is located on the distal end side. May be good.
In this case, the rib has a solid portion located on the tip side. Therefore, by not forming the entire rib in a hollow shape, it is possible to prevent the tip of the rib from becoming excessively thin. Therefore, the strength of the rib can be increased by facilitating the molding of the rib and forming a large rib welding surface formed at the tip of the rib.

また、前記中空部は、前記側壁部のうち、前記貯留部側に向けて立ち上がり、先端部同士が接合された２つの脚部であり、前記中実部は、前記脚部の先端部から、前記貯留部側に向けて突出する突出部であってもよい。
この場合には、中空部が２つの脚部であるため、中空部の強度を確保することができるとともに、貯留部側に向けて突出する中実部の先端に、リブ溶着面を容易に設けることができる。 Further, the hollow portion is two legs of the side wall portion that rise toward the storage portion side and the tip portions are joined to each other, and the solid portion is formed from the tip portion of the leg portion. It may be a protruding portion that protrudes toward the storage portion side.
In this case, since the hollow portion has two legs, the strength of the hollow portion can be ensured, and a rib welding surface is easily provided at the tip of the solid portion protruding toward the storage portion side. be able to.

本発明によれば、成形の自由度を向上してウォッシャタンクのレイアウト性を確保しながら、仮に貯留部に充満したウォッシャ液が凍結しても破裂するのを防止することができる。 According to the present invention, it is possible to prevent the washer liquid filled in the storage portion from bursting even if it freezes, while improving the degree of freedom of molding and ensuring the layout of the washer tank.

The pair of tank walls 11 and 12 are separately molded from a synthetic resin. The washer tank 10 has a rectangular shape that is longer in the lateral direction (one of the horizontal directions) than in the vertical direction (gravity direction) when viewed from the front.

一対のタンク壁１１、１２それぞれにおける開口周縁部には、タンク溶着面１１Ａ、１２Ａが形成されている。
ウォッシャタンク１０は、それぞれのタンク溶着面１１Ａ、１２Ａ同士が、互いに溶着されて、接合されることで閉断面構造を形成している。 Tank welding surfaces 11A and 12A are formed on the peripheral edges of the openings in the pair of tank walls 11 and 12, respectively.
The washer tank 10 has a closed cross-sectional structure when the welded surfaces 11A and 12A of the tanks are welded to each other and joined to each other.

図示の例では、リブ２１、２２は、流入孔１５の開口周縁部に沿って、正面視で流入孔１５を上方から囲む位置に配置されている。リブ２１、２２は正面視で下方に向けて開口するＵ字状をなしている。 As shown in FIG. 4, the ribs 21 and 22 are arranged so as to surround the inflow hole 15 from above and open downward in front view of the inflow hole 15, and are arranged on each side. The whole is joined to the side wall portion 13.
In the illustrated example, the ribs 21 and 22 are arranged at positions that surround the inflow hole 15 from above in front view along the peripheral edge of the opening of the inflow hole 15. The ribs 21 and 22 have a U shape that opens downward when viewed from the front.

また、第１タンク壁１１に形成された第１リブ２１は、２つの側壁部１３のうちの一方を凹ませることで、貯留部Ａ側に向けて突出した状態で形成されている。なお、２つの側壁部１３のうちの両方を凹ませることで、リブ２１、２２を形成してもよい。 Further, the first rib 21 formed on the first tank wall 11 is formed in a state of protruding toward the storage portion A side by denting one of the two side wall portions 13. The ribs 21 and 22 may be formed by denting both of the two side wall portions 13.

次に、このように構成されたウォッシャタンク１０にウォッシャ液Ｗを充填した状態を説明する。図４に示すように、流入孔１５から貯留部Ａにウォッシャ液Ｗを充填すると、貯留部Ａ内にウォッシャ液Ｗが貯留される。そして、ウォッシャ液Ｗの水面が、リブ２１、２２の下端縁と同等の位置に位置すると、貯留部Ａ内のうち、ウォッシャ液Ｗの水面よりも上方に位置する部分から空気が抜ける経路がなくなり、ウォッシャ液Ｗの貯留部Ａ内への充填が停止する。すなわち、流入孔１５の正面視でリブ２１、２２の外側に位置し、かつウォッシャ液Ｗの水面よりも上方に位置する部分にエア溜り部Ｂが形成される。 Next, a state in which the washer liquid W is filled in the washer tank 10 configured in this way will be described. As shown in FIG. 4, when the washer fluid W is filled in the storage portion A from the inflow hole 15, the washer fluid W is stored in the reservoir A. When the water surface of the washer fluid W is located at a position equivalent to the lower edge of the ribs 21 and 22, there is no path for air to escape from the portion of the storage portion A above the water surface of the washer fluid W. , The filling of the washer fluid W into the storage portion A is stopped. That is, the air collecting portion B is formed in a portion located outside the ribs 21 and 22 and above the water surface of the washer fluid W in the front view of the inflow hole 15.

以上説明したように、一対のタンク壁１１、１２が水平方向に互いに対向して配置されている。このため、ウォッシャタンク１０の水平方向の凹凸形状に対する成形の自由度が向上し、エンジンルーム内で隣り合う部材に合わせたウォッシャタンク１０のレイアウト性を確保することができる。
また、一対のリブ２１、２２同士が溶着されるリブ溶着面２１Ａ、２２Ａ同士が、タンク溶着面１１Ａ、１２Ａと同一平面上に位置している。このため、タンク溶着面の溶着作業において、高熱の鉄板をタンク溶着面１１Ａ、１２Ａに当接させた際に、リブ溶着面２１Ａ、２２Ａにも同時に当接させることが可能になる。これにより、縦割タイプのウォッシャタンク１０であっても、タンク溶着面およびリブ溶着面それぞれにおける溶着作業を、同時に効率的に行うことができる。 As described above, the pair of tank walls 11 and 12 are arranged so as to face each other in the horizontal direction. Therefore, the degree of freedom of molding of the washer tank 10 with respect to the uneven shape in the horizontal direction is improved, and the layout of the washer tank 10 can be ensured according to the adjacent members in the engine room.
Further, the rib welding surfaces 21A and 22A to which the pair of ribs 21 and 22 are welded are located on the same plane as the tank welding surfaces 11A and 12A. Therefore, in the welding work of the tank welding surface, when the hot iron plate is brought into contact with the tank welding surfaces 11A and 12A, it is possible to bring them into contact with the rib welding surfaces 21A and 22A at the same time. As a result, even in the vertically split type washer tank 10, the welding work on each of the tank welding surface and the rib welding surface can be efficiently performed at the same time.

また、リブ２１、２２が、流入孔１５の正面視で、流入孔１５を上方から囲むように、かつ下方が開放されるように配置されているとともに、各側辺の全体がそれぞれ側壁部１３に接合されている。このため、貯留部Ａのうち、流入孔１５を囲むリブ２１、２２の外側に位置する部分に、ウォッシャ液Ｗが充填されにくくなる空間であるエア溜り部Ｂを形成することができる。これにより、貯留部Ａにウォッシャ液Ｗが充満するのを抑制し、貯留部Ａに充満したウォッシャ液Ｗが凍結することで、破裂するのを防止することができる。 Further, the ribs 21 and 22 are arranged so as to surround the inflow hole 15 from above and open below in the front view of the inflow hole 15, and the entire side surface of each side is the side wall portion 13. It is joined to. Therefore, an air collecting portion B, which is a space in which the washer fluid W is less likely to be filled, can be formed in a portion of the storage portion A located outside the ribs 21 and 22 surrounding the inflow hole 15. As a result, it is possible to prevent the reservoir A from being filled with the washer fluid W, and to prevent the washer fluid W filled in the reservoir A from freezing and bursting.

また、リブ２１、２２が流入孔１５の開口周縁部に沿って、流入孔１５を上方から囲むように配置されているので、流入孔１５の開口周縁部とリブ２１、２２との間に空間が形成されるのを防ぐことができる。これにより、流入孔１５を囲むリブ２１、２２の外側に形成されるエア溜り部Ｂを、可能な限り大きくすることができる。 Further, since the ribs 21 and 22 are arranged along the opening peripheral edge of the inflow hole 15 so as to surround the inflow hole 15 from above, there is a space between the opening peripheral edge of the inflow hole 15 and the ribs 21 and 22. Can be prevented from being formed. As a result, the air collecting portion B formed on the outside of the ribs 21 and 22 surrounding the inflow hole 15 can be made as large as possible.

また、２つの側壁部１３のうちの少なくともいずれか一方を凹ませることで、リブ２１が形成されているので、側壁部１３およびリブ２１の厚みを全域にわたって均一にすることができる。これにより、側壁部１３およびリブ２１が、例えば合成樹脂材料の射出成形等により形成された場合に、側壁部１３およびリブ２１に、局部的に表面が凹むヒケが生じるのを抑制することができる。 Further, since the rib 21 is formed by denting at least one of the two side wall portions 13, the thickness of the side wall portion 13 and the rib 21 can be made uniform over the entire area. As a result, when the side wall portion 13 and the rib 21 are formed by, for example, injection molding of a synthetic resin material, it is possible to prevent the side wall portion 13 and the rib 21 from having a sink mark whose surface is locally recessed. ..

（変形例）
次に、リブ２１、２２の変形例について説明する。
図５（ａ）に示すように、第１変形例に係るリブ２１Ｂ、２２Ｂは、流入孔１５の周縁の一部に設けられ、流入孔１５の正面視で下方に向けて開口した矩形状をなしている。
図５（ｂ）に示すように、第２変形例に係るリブ２１Ｃ、２２Ｃは、流入孔１５の正面視で流入孔１５を横方向に挟み込むように配置された一対の板状をなし、ウォッシャタンク１０の天壁部１６と各別に接続されている。この場合、一対のリブ２１Ｃ、２２Ｃの内側のうち、流入孔１５の開口周縁部よりも上方に位置する部分にもエア溜り部Ｂが形成される。 (Modification example)
Next, a modification of the ribs 21 and 22 will be described.
As shown in FIG. 5A, the ribs 21B and 22B according to the first modification are provided on a part of the peripheral edge of the inflow hole 15, and have a rectangular shape that opens downward in the front view of the inflow hole 15. I'm doing it.

It is separately connected to the top wall portion 16 of the tank 10. In this case, the air collecting portion B is also formed inside the pair of ribs 21C and 22C, which is located above the peripheral edge of the opening of the inflow hole 15.

図５（ｃ）に示すように、第３変形例に係るリブ２１Ｄ、２２Ｄは、第２変形例に係るリブ２１Ｃ、２２Ｃを横方向に傾斜させた構成となっている。すなわち、本変形例に係るリブ２１Ｄ、２２Ｄは天壁部１６から下方に向かうに従い漸次、横方向に向けて延びている。
図５（ｄ）に示すように、第４変形例に係るリブ２１Ｅ、２２Ｅは、流入孔１５の横方向の一方側にのみ配置されている。 As shown in FIG. 5C, the ribs 21D and 22D according to the third modification have a configuration in which the ribs 21C and 22C according to the second modification are inclined in the lateral direction. That is, the ribs 21D and 22D according to this modification gradually extend in the lateral direction from the top wall portion 16 downward.
As shown in FIG. 5D, the ribs 21E and 22E according to the fourth modification are arranged only on one side in the lateral direction of the inflow hole 15.

（第２実施形態）
以下、図６から図１０を参照し、本発明の第２実施形態に係るウォッシャタンク１０Ｂについて説明する。なお、以下の説明において、第１実施形態と同一の構成については同一の符号を付し、その説明を省略する。 (Second Embodiment)
Hereinafter, the washer tank 10B according to the second embodiment of the present invention will be described with reference to FIGS. 6 to 10. In the following description, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

図６および図７に示すように、ウォッシャタンク１０Ｂは、正面視で横方向よりも上下方向に長い矩形状をなしている。また、リブ溶着面２１Ａ、２２Ａ、およびタンク壁１１、１２におけるタンク溶着面１１Ａ、１２Ａは上下方向に対して傾斜して延びている。
すなわち、リブ溶着面２１Ａ、２２Ａ、およびタンク壁１１、１２におけるタンク溶着面１１Ａ、１２Ａは、上方に向かうに従い漸次、タンク壁１１の開口する方向に向けて延びている。 As shown in FIGS. 6 and 7, the washer tank 10B has a rectangular shape that is longer in the vertical direction than in the horizontal direction when viewed from the front. Further, the rib welding surfaces 21A and 22A and the tank welding surfaces 11A and 12A on the tank walls 11 and 12 extend so as to be inclined in the vertical direction.
That is, the rib welding surfaces 21A and 22A and the tank welding surfaces 11A and 12A on the tank walls 11 and 12 gradually extend toward the opening of the tank wall 11 as they go upward.

本実施形態に係るウォッシャタンク１０Ｂでは、流入孔１５は、ウォッシャタンク１０Ｂの天壁部１６に形成されている。
流入孔１５に設けられたホース３０は、ウォッシャタンク１０Ｂの内側に挿通されている。 In the washer tank 10B according to the present embodiment, the inflow hole 15 is formed in the top wall portion 16 of the washer tank 10B.
The hose 30 provided in the inflow hole 15 is inserted inside the washer tank 10B.

一対のリブ２１Ｆ、２２Ｆは、上下方向に沿って延在するとともに、上方の上辺における全体が、天壁部１６と接合されているとともに、各側辺の全体が、それぞれ側壁部１３に接合されている。
リブ２１Ｆ、２２Ｆの上下方向の大きさは、ホース３０のうち、貯留部Ａ内に位置する部分の上下方向の大きさよりも大きくなっている。 The pair of ribs 21F and 22F extend in the vertical direction, and the entire upper upper side is joined to the top wall portion 16, and the entire side surface is joined to the side wall portion 13, respectively. ing.
The vertical size of the ribs 21F and 22F is larger than the vertical size of the portion of the hose 30 located in the storage portion A.

図９に示すように、第１タンクの第１リブ２１Ｆは、基端側に位置し、２つの側壁部１３のうちの少なくともいずれか一方を凹ませた凹部からなる中空部３１と、先端側に位置する中実部３２と、を有している。中実部３２は表裏面が横方向を向く板状をなしている。中実部３２の先端に、リブ溶着面２１Ａ、２２Ａが形成されている。 As shown in FIG. 9, the first rib 21F of the first tank is located on the base end side, and has a hollow portion 31 formed of a recess in which at least one of the two side wall portions 13 is recessed, and a tip side. It has a solid portion 32 located at. The solid portion 32 has a plate shape with the front and back surfaces facing laterally. Rib welding surfaces 21A and 22A are formed at the tip of the solid portion 32.

中空部３１は、側壁部１３のうち、貯留部Ａ側に向けて立ち上がり、先端部同士が接合された２つの脚部であり、中実部３２は、脚部の先端部から、貯留部Ａ側に向けて突出する突出部である。中空部３１および中実部３２それぞれにおける厚み寸法は、互いに同等となっている。 The hollow portion 31 is two leg portions of the side wall portion 13 that rise toward the storage portion A side and the tips thereof are joined to each other, and the solid portion 32 is a storage portion A from the tip portion of the leg portion. It is a protruding portion that protrudes toward the side. The thickness dimensions of the hollow portion 31 and the solid portion 32 are the same as each other.

次に、このように構成されたウォッシャタンク１０Ｂにウォッシャ液Ｗを充填した状態を説明する。図１０に示すように、流入孔１５からホース３０の内側を通して貯留部Ａにウォッシャ液Ｗを充填すると、貯留部Ａ内にウォッシャ液Ｗが貯留される。
そして、ウォッシャ液Ｗの水面が、リブ２１Ｆ、２２Ｆの下端縁と同等の位置になると、貯留部Ａ内のうち、ウォッシャ液Ｗの水面よりも上方に位置する部分からの空気が抜ける経路がなくなり、ウォッシャ液Ｗの貯留部Ａ内への充填が停止する。すなわち、リブ２１Ｆ、２２Ｆを挟んで流入孔１５と水平方向で反対側に位置する部分であって、かつウォッシャ液Ｗの水面よりも上方に位置する部分にエア溜り部Ｂが形成される。
また、リブ２１Ｆ、２２Ｆを挟んで流入孔１５側の空間では、ホース３０の下端縁よりも上方に位置する部分にエア溜り部Ｂが形成される。 Next, a state in which the washer liquid W is filled in the washer tank 10B configured as described above will be described. As shown in FIG. 10, when the washer fluid W is filled in the storage portion A through the inside of the hose 30 through the inflow hole 15, the washer fluid W is stored in the reservoir A.
Then, when the water surface of the washer fluid W is at a position equivalent to the lower end edges of the ribs 21F and 22F, there is no path for air to escape from the portion of the storage portion A located above the water surface of the washer fluid W. , The filling of the washer fluid W into the storage portion A is stopped. That is, the air collecting portion B is formed at a portion located on the side opposite to the inflow hole 15 in the horizontal direction with the ribs 21F and 22F sandwiched between the ribs 21F and 22F, and at a portion located above the water surface of the washer fluid W.
Further, in the space on the inflow hole 15 side across the ribs 21F and 22F, an air collecting portion B is formed in a portion located above the lower end edge of the hose 30.

以上説明したように、リブ２１Ｆ、２２Ｆが上下方向に沿って延在するとともに、上方の上辺における全体が、天壁部１６と接続されているとともに、各側辺の全体が、それぞれ側壁部１３に接合されている。このため、貯留部Ａのうち、リブ２１Ｆ、２２Ｆを挟んで流入孔１５と水平方向で反対側に位置する部分に、ウォッシャ液Ｗが充填されにくくなる空間であるエア溜り部Ｂを形成することができる。これにより、貯留部Ａにウォッシャ液Ｗが充満するのを抑制し、貯留部Ａに充満したウォッシャ液Ｗが凍結することで、破裂するのを防止することができる。 As described above, the ribs 21F and 22F extend in the vertical direction, the entire upper upper side is connected to the top wall portion 16, and the entire side surface portion 13 is provided. It is joined to. For this reason, an air collecting portion B, which is a space in which the washer fluid W is less likely to be filled, is formed in a portion of the storage portion A located on the side opposite to the inflow hole 15 in the horizontal direction with the ribs 21F and 22F interposed therebetween. Can be done. As a result, it is possible to prevent the reservoir A from being filled with the washer fluid W, and to prevent the washer fluid W filled in the reservoir A from freezing and bursting.

また、リブ２１Ｆ、２２Ｆの上下方向の大きさが、ホース３０のうち、貯留部Ａ内に位置する部分の上下方向の大きさよりも大きくなっている。このため、エンジンルーム内のレイアウトによって、貯留部Ａ内にホース３０を配置する空間を大きく確保できない場合であっても、リブ２１Ｆ、２２Ｆにより貯留部Ａ内にエア溜りを確実に確保することができる。したがって、図１０のように、ホース３０を挿入方向に延長した位置と重なるように、側壁部１３を重力方向に対して傾斜させた形状とすることも可能となる。 Further, the vertical size of the ribs 21F and 22F is larger than the vertical size of the portion of the hose 30 located in the storage portion A. Therefore, even if a large space for arranging the hose 30 cannot be secured in the storage section A due to the layout in the engine room, the ribs 21F and 22F can surely secure the air pool in the storage section A. can. Therefore, as shown in FIG. 10, the side wall portion 13 can be formed to be inclined with respect to the gravity direction so as to overlap the position where the hose 30 is extended in the insertion direction.

また、リブ２１Ｆが先端側に位置する中実部３２を有している。このため、リブ２１Ｆの全体を中空状に形成しないことで、リブ２１Ｆの先端が過剰に細くなるのを防ぐことができる。よって、リブ２１Ｆの成形を容易にするとともに、リブ溶着面２１Ａを大きく形成することで、リブ２１Ｆ、２２Ｆの強度を大きくすることができる。
また、中空部３１が２つの脚部であるため、中空部３１の強度を確保することができるとともに、貯留部Ａ側に向けて突出する中実部３２の先端に、リブ溶着面２１Ａを容易に設けることができる。 Further, the rib 21F has a solid portion 32 located on the tip end side. Therefore, by not forming the entire rib 21F in a hollow shape, it is possible to prevent the tip of the rib 21F from becoming excessively thin. Therefore, the strength of the ribs 21F and 22F can be increased by facilitating the molding of the ribs 21F and forming the rib welding surface 21A large.
Further, since the hollow portion 31 has two legs, the strength of the hollow portion 31 can be ensured, and the rib welding surface 21A can be easily formed at the tip of the solid portion 32 protruding toward the storage portion A side. Can be provided in.

例えば、上記各実施形態においては、第１リブ２１、２１Ｆが、第１タンク壁１１を凹ませることで、貯留部Ａ側に突出されて形成されている構成を示したが、このような態様に限られない。第１リブ２１、２１Ｆは第１タンク壁１１を凹ませることなく形成されてもよい。 For example, in each of the above embodiments, the first ribs 21 and 21F are formed by denting the first tank wall 11 so as to project toward the storage portion A side. Not limited to. The first ribs 21 and 21F may be formed without denting the first tank wall 11.

また、上記第２実施形態においては、リブ２１Ｆ、２２Ｆの上下方向の大きさが、ホース３０のうち、貯留部Ａ内に位置する部分の上下方向の大きさよりも大きい構成を示したが、このような態様に限られない。リブの上下方向の大きさは、ホース３０のうち、貯留部Ａ内に位置する部分の上下方向の大きさよりも小さくてもよい。 Further, in the second embodiment, the vertical size of the ribs 21F and 22F is larger than the vertical size of the portion of the hose 30 located in the storage portion A. It is not limited to such an aspect. The vertical size of the rib may be smaller than the vertical size of the portion of the hose 30 located in the storage portion A.

また、上記第２実施形態においては、リブ２１Ｆのみが中空部３１と中実部３２とを備えている構成を示したが、このような態様に限られない。リブ２１Ｆ、２２Ｆの両方が、中空部３１と中実部３２とを備えていてもよい。また、リブ２１Ｆ、２２Ｆの全体が、中空部３１又は中実部３２のうちのいずれか一方により形成されてもよい。
また、中空部３１および中実部３２の形状については、任意に変更することができる。 Further, in the second embodiment, only the rib 21F has a configuration in which the hollow portion 31 and the solid portion 32 are provided, but the present invention is not limited to such an embodiment. Both the ribs 21F and 22F may include a hollow portion 31 and a solid portion 32. Further, the entire ribs 21F and 22F may be formed by either the hollow portion 31 or the solid portion 32.
