By sandwiching the closing member between the case and the dash panel, the panel hole through which the pipe penetrates is closed.
　閉塞部材は、パネル孔の縁に対して密着しているパッキンに加えて、パッキンの径よりも大きい径を備えたゴムシートと、を有している。ダッシュパネルの車室側の面には、吸音シートが貼られている。吸音シートには、配管が貫通しているシート孔が形成されている。ゴムシートは、シート孔を塞いでいる。即ち、閉塞部材は、パネル孔に加えて、シート孔も塞いでいる。エンジンルームから車室へ伝わる音を効果的に遮ることができる。 The closing member has, in addition to the packing that is in close contact with the edge of the panel hole, a rubber sheet having a diameter larger than the diameter of the packing. A sound absorbing sheet is attached to the surface of the dash panel on the passenger compartment side. The sound absorbing sheet is formed with a sheet hole through which the pipe penetrates. The rubber sheet closes the sheet hole. That is, the closing member closes the seat hole in addition to the panel hole. The sound transmitted from the engine room to the passenger compartment can be effectively blocked.

　上記の通り、ゴムシートは弾性を有しているため、ゴムシートはシート孔の周縁に対して密着しやすい。一方、その弾性の特性ゆえゴムシートは変形しやすい。ゴムシートのうち、ケースに押されていない外周の縁は、ケース側に折れ曲がっている。すなわち、パネル孔の径方向外側に向かうにつれて、ダッシュパネルとゴムシートの間隔が広くなっている。間隔が広くなると、車室内へ音が伝わりやすくなる。遮音性に関して改良の余地がある。 As mentioned above, since the rubber sheet has elasticity, the rubber sheet easily adheres to the peripheral edge of the sheet hole. On the other hand, the rubber sheet is easily deformed due to its elastic characteristics. Of the rubber sheets, the outer peripheral edge that is not pressed by the case is bent toward the case. That is, the distance between the dash panel and the rubber sheet becomes wider toward the outer side in the radial direction of the panel hole. The wider the interval, the easier it is for the sound to be transmitted to the passenger compartment. There is room for improvement in terms of sound insulation.

The inner peripheral surface 71c of the first plate hole 71g and the outer peripheral surface 61a of the first pipe 61 are separated from each other, and a gap is formed. That is, the inner diameter d1 of the sound insulation plate 71 is larger than the outer diameter d2 of the first pipe 61 (d1> d2). Similarly, the inner peripheral surface 44c of the case hole 44b and the outer peripheral surface 61a of the first pipe 61 are separated from each other, and a gap is formed.
　第１のパネル孔１１の軸線Ａｘに沿う方向からみて（図４（ａ）参照）、第１のプレート孔７１ｇは、第１のパネル孔１１に囲われている。即ち、遮音プレート７１の内径ｄ１は、第１のパネル孔１１の径ｄ３よりも小さい（ｄ１＜ｄ３）。 The first plate hole 71g is surrounded by the first panel hole 11 when viewed from the direction along the axis Ax of the first panel hole 11 (see FIG. 4A).

The first closing member 70 has a metal sound insulating plate 71. The density of metal is higher than that of elastic members and resins. Generally, a material having a high density has high sound insulation performance. Therefore, the sound insulation plate 71 can surely block the sound traveling along the axis Ax direction of the first panel hole 11.
　加えて、弾性素材や樹脂等と比較すると、金属製の遮音プレート７１は変形しにくい。第１の閉塞部材７０が、第１の突出部４４と、ダッシュパネル１０とに挟まれても、ダッシュパネル１０の後面１０ａと、遮音プレート７１の前面７１ｆとの間隔Ｌは、一定に保たれる。第１のパネル孔１１の径方向に進む音が伝わることを抑制できる。 In addition, the metal sound insulation plate 71 is less likely to be deformed than the elastic material or resin. Even if the first closing member 70 is sandwiched between the first protrusion 44 and the dash panel 10, the distance L between the rear surface 10a of the dash panel 10 and the front surface 71f of the sound insulation plate 71 is kept constant. Is done. It is possible to suppress the transmission of sound traveling in the radial direction of the first panel hole 11.
　加えて、遮音プレート７１の両面７１ｂ,７１ｆにライナ８１,８２が設けられている。第１のライナ８１は第１の突出部４４の前面４４ａに密着する。第２のライナ８２は吸音シート３０に密着する。よって、さらに第１パネル孔１１の径方向に進む音が伝わることを抑制できる。 In addition, liners 81 and 82 are provided on both sides 71b and 71f of the sound insulation plate 71. The first liner 81 is in close contact with the front surface 44a of the first protrusion 44. The second liner 82 is in close contact with the sound absorbing sheet 30. Therefore, it is possible to further suppress the transmission of the sound traveling in the radial direction of the first panel hole 11.
　図４Ａを参照する。加えて、第１のプレート孔７１ｇは、第１のパネル孔１１に囲われている。軸線Ａｘに沿って第１のパネル孔１１を通過した音の一部は、遮音プレート７１の内周の縁７１ｄに遮られる。 Refer to FIG. 4A. In addition, the first plate hole 71g is surrounded by the first panel hole 11. A part of the sound that has passed through the first panel hole 11 along the axis Ax is blocked by the inner peripheral edge 71d of the sound insulation plate 71.
　なお、第１の閉塞部材７０の構成は、上記の構成に限らない。遮音プレート７１の前面７１ａ又は後面７１ｂの一方のみにライナを設ける構成でもよい。即ち、第２のライナ８２を廃して、遮音プレート７１が吸音シート３０に対して直接に密着する構成や、第１のライナ８１を廃して、遮音プレート７１がケース４０の前面４４ａに対して直接に密着する構成でもよい。さらに、遮音プレート７１の外径、第１のライナ８１～第３のライナ８３の外径も適宜変更できる。 The configuration of the first closing member 70 is not limited to the above configuration. A liner may be provided only on one of the front surface 71a or the rear surface 71b of the sound insulation plate 71. That is, the second liner 82 is eliminated and the sound insulation plate 71 is in direct contact with the sound absorbing sheet 30, or the first liner 81 is eliminated and the sound insulation plate 71 is directly attached to the front surface 44a of the case 40. It may be configured to be in close contact with. Further, the outer diameter of the sound insulating plate 71 and the outer diameters of the first liner 81 to the third liner 83 can be appropriately changed.
　図１及び図２を参照する。第２の配管６２には、第２の閉塞部材９１が取り付けられている。第２の閉塞部材９１は、第２の配管６２が第２のパネル孔１２及び第２のシート孔３２を貫通したときに、第２のパネル孔１２及び第２のシート孔３２を車室Ｒ側から塞ぐ部材である。 Refer to FIGS. 1 and 2. A second closing member 91 is attached to the second pipe 62. When the second pipe 62 penetrates the second panel hole 12 and the second seat hole 32, the second closing member 91 fills the second panel hole 12 and the second seat hole 32 in the passenger compartment R. It is a member that closes from the side.
　第２の閉塞部材９１の構成は、第１の閉塞部材７０の構成と同一である。第２の閉塞部材９１の説明は省略する。 The configuration of the second closing member 91 is the same as the configuration of the first closing member 70. The description of the second closing member 91 will be omitted.
　ケース４０の対向面４３は、ダッシュパネル１０側へ向かって突出している第２の突出部４５を有している。第２の突出部４５の構成は、第１の突出部４４の構成と同一である。第２の突出部４５の説明は省略する。 The facing surface 43 of the case 40 has a second protruding portion 45 that protrudes toward the dash panel 10 side. The configuration of the second protrusion 45 is the same as the configuration of the first protrusion 44. The description of the second protrusion 45 will be omitted.
　第３の配管６３に対しては、第５の配管６５が接続可能である。第４の配管６４に対しては、第６の配管６６が接続可能である。第３の配管６３及び第４の配管６４には、第３の閉塞部材９２が取り付けられている。第３の閉塞部材９２は、第５の配管６５及び第６の配管６６が貫通する第３のパネル孔１３及び第３のシート孔３３を車室Ｒ側から塞ぐ部材である。 The fifth pipe 65 can be connected to the third pipe 63. A sixth pipe 66 can be connected to the fourth pipe 64. A third closing member 92 is attached to the third pipe 63 and the fourth pipe 64. The third closing member 92 is a member that closes the third panel hole 13 and the third seat hole 33 through which the fifth pipe 65 and the sixth pipe 66 penetrate from the vehicle interior R side.
　なお、第３のパネル孔１３と、第３のシート孔３３とは、略トラック形状である（図１参照）。第３の閉塞部材９２は、これらの孔１３,３３を塞ぐことが可能となるような形状である。すなわち、閉塞部材は、ダッシュパネルの孔の形状に沿って、適宜変更することができる。 The third panel hole 13 and the third seat hole 33 have a substantially track shape (see FIG. 1). The third closing member 92 has a shape capable of closing these holes 13, 33. That is, the closing member can be appropriately changed along the shape of the hole in the dash panel.
　第３の閉塞部材９２の基本的な構成は、第１の閉塞部材７０と同一である。第３の閉塞部材９２も、遮音プレートやライナを有している。第３の閉塞部材９２の詳細な説明は省略する。 The basic configuration of the third closing member 92 is the same as that of the first closing member 70. The third closing member 92 also has a sound insulating plate and a liner. A detailed description of the third closing member 92 will be omitted.
　さらに、ケース４０の対向面４３は、ダッシュパネル１０側へ向かって突出している第３の突出部４６を有している。第３の突出部４６の基本的な構成は、第１の突出部４４の構成と同一である。第３の突出部４６の説明は省略する。 Further, the facing surface 43 of the case 40 has a third protruding portion 46 protruding toward the dash panel 10 side. The basic configuration of the third protrusion 46 is the same as the configuration of the first protrusion 44. The description of the third protrusion 46 will be omitted.
　次に、実施例２～実施例４による車両用空調装置２０Ａ～２０Ｃについて説明する。実施例１と比較すると、実施例２～実施例４による車両用空調装置２０Ａ～２０Ｃは、遮音プレートの形状が異なる。実施例１と共通する構成については、同一の符号を付し、説明を省略する。実施例２～実施例４による車両用空調装置２０Ａ～２０Ｃも実施例１と同一の効果を有する。 Next, the vehicle air conditioners 20A to 20C according to the second to fourth embodiments will be described. As compared with Example 1, the vehicle air conditioners 20A to 20C according to Examples 2 to 4 have different shapes of sound insulation plates. The same reference numerals are given to the configurations common to those of the first embodiment, and the description thereof will be omitted. The vehicle air conditioners 20A to 20C according to the second to fourth embodiments have the same effect as that of the first embodiment.
　＜実施例２＞
　図５Ａ及び図５Ｂを参照する。車両用空調装置２０Ａの第１の閉塞部材７０Ａの遮音プレート７２の前面７２ｆと、後面７２ｂとは、ケース４０の前面４４ａへ向かって凸状に膨らむように湾曲している。 <Example 2>
See FIGS. 5A and 5B. The front surface 72f and the rear surface 72b of the sound insulating plate 72 of the first closing member 70A of the vehicle air conditioner 20A are curved so as to bulge convexly toward the front surface 44a of the case 40.
　遮音プレート７２は、全体としてパラボラアンテナ状を呈しており、中心にプレート孔７２ｇが形成されている。遮音プレート７２は、少なくとも前面７２ｆがケース４０の前面４４ａへ向かって凸状に膨らむように湾曲していれば、全体の形状は問わない。例えば、遮音プレート７２は、矩形の平板を撓ませた形状であってもよい。 The sound insulation plate 72 has a parabolic antenna shape as a whole, and a plate hole 72 g is formed in the center. The overall shape of the sound insulation plate 72 does not matter as long as the front surface 72f is curved so as to bulge convexly toward the front surface 44a of the case 40. For example, the sound insulation plate 72 may have a shape in which a rectangular flat plate is bent.
　エンジンルームＥから車室Ｒに侵入した音は、遮音プレート７２の前面７２ｆに反射し、第１のパネル孔１１の軸線Ａｘへ向かう。即ち、遮音プレート７２に反射した音の拡散を抑制できる。 The sound that has entered the vehicle interior R from the engine room E is reflected on the front surface 72f of the sound insulation plate 72 and heads toward the axis Ax of the first panel hole 11. That is, the diffusion of the sound reflected on the sound insulation plate 72 can be suppressed.
　＜実施例３＞
　図６を参照する。車両用空調装置２０Ｂの第１の閉塞部材７０Ｂの遮音プレート７３の外径は、第１のライナ８１及び第２のライナ８２の外径よりも大きい。遮音プレート７３の外周の縁７３ｅは、ダッシュパネル１０側に屈曲している。そのため、遮音プレート７３の剛性が高まる。遮音プレート７３は反りにくくなり、遮音プレート７３の前面７３ｆ及び後面７３ｂの平面度が維持されやすい。後面７３ｂに対する第１のライナ８１の密着性と、前面７３ｆに対する第２のライナ８２の密着性が高まり、ライナ８１，８２が圧縮される。よって第１の閉塞部材７３全体の遮音性が高まる。 <Example 3>
See FIG. The outer diameter of the sound insulating plate 73 of the first closing member 70B of the vehicle air conditioner 20B is larger than the outer diameter of the first liner 81 and the second liner 82. The outer peripheral edge 73e of the sound insulation plate 73 is bent toward the dash panel 10. Therefore, the rigidity of the sound insulation plate 73 is increased. The sound insulation plate 73 is less likely to warp, and the flatness of the front surface 73f and the rear surface 73b of the sound insulation plate 73 is likely to be maintained. The adhesion of the first liner 81 to the rear surface 73b and the adhesion of the second liner 82 to the front surface 73f are enhanced, and the liners 81 and 82 are compressed. Therefore, the sound insulation of the entire first closing member 73 is enhanced.
　外周の縁７３ｅは、ケース４０側へ屈曲させてもよい。さらに、外周の縁７３ｅは、湾曲させてもよく、縁７３ａの形状や曲げの程度は問わない。なお、遮音プレート７３の外周の縁７３ｅが、ダッシュパネル１０側へ屈曲している場合、屈曲した縁７３ａと、ダッシュパネル１０との間隔が狭まる。車室Ｒに侵入し、第１のパネル孔１１の径方向外側へ向かう音を遮りやすくなる。 The outer peripheral edge 73e may be bent toward the case 40 side. Further, the outer peripheral edge 73e may be curved, and the shape and degree of bending of the edge 73a are not limited. When the outer peripheral edge 73e of the sound insulating plate 73 is bent toward the dash panel 10, the distance between the bent edge 73a and the dash panel 10 is narrowed. It becomes easy to invade the vehicle interior R and block the sound toward the radial outer side of the first panel hole 11.
　＜実施例４＞
　図７を参照する。車両用空調装置２０Ｃの第１の閉塞部材７０Ｃの遮音プレート７４には、第１の配管６１が貫通している第１のプレート孔７４ｇに加えて、複数の第２のプレート孔７４ｈが形成されている（図６Ｂには、一部の孔７４ｈが示されている）。各々の第２のプレート孔７４ｈは、第１のライナ８１と第２のライナ８２とで挟まれることにより、塞がれる。さらに第１のライナ８１、第２のライナ８２、吸音シート３０及びダッシュパネル１０が第２のプレート孔７４ｈの周縁から前後方向へ密着し、圧縮している。そのため、遮音効果を保ったまま遮音プレート７４を軽量化することができる。第２のプレート孔７４ｈの個数及び位置は、適宜変更することができる。第２のプレート孔７４ｈは、ケース４０が車室Ｒに配置されたときに、各パネル孔（第１のパネル孔１１、第２のパネル孔１２、第３のパネル孔１３）の軸線Ａｘに沿う方向から見て、各パネル孔１１,１２,１３の径方向外側に配置されている。即ち、各パネル孔１１,１２,１３と、第２のプレート孔７４ｈとは、軸線Ａｘに沿う方向について重なっていない。このように第２のプレート７４ｈが配置されているので、エンジンルームＥから侵入した音が、第２のプレート孔７４ｈを直接的に通過することが防止される。 <Example 4>
See FIG. 7. In the sound insulating plate 74 of the first closing member 70C of the vehicle air conditioner 20C, in addition to the first plate hole 74g through which the first pipe 61 penetrates, a plurality of second plate holes 74h are formed. (FIG. 6B shows some holes 74h). Each second plate hole 74h is closed by being sandwiched between the first liner 81 and the second liner 82. Further, the first liner 81, the second liner 82, the sound absorbing sheet 30, and the dash panel 10 are in close contact with each other in the front-rear direction from the peripheral edge of the second plate hole 74h and are compressed. Therefore, the weight of the sound insulation plate 74 can be reduced while maintaining the sound insulation effect. The number and position of the second plate holes 74h can be changed as appropriate. The second plate hole 74h is formed in the axis Ax of each panel hole (first panel hole 11, second panel hole 12, third panel hole 13) when the case 40 is arranged in the vehicle interior R. It is arranged on the radial outer side of each panel hole 11, 12, 13 when viewed from the direction along the line. That is, the panel holes 11, 12, 13 and the second plate hole 74h do not overlap in the direction along the axis Ax. Since the second plate 74h is arranged in this way, it is possible to prevent the sound that has entered from the engine room E from directly passing through the second plate hole 74h.
　本発明の作用及び効果を奏する限りにおいて、本発明は、実施例に限定されるものではない。例えば、配管６３，６４に対して略トラック状の閉塞部材９２が設けられているように、配管６１，６２に対してもそれぞれが一体となった閉塞部材が設けられていてもよい。即ち、複数の孔を単一の閉塞部材により塞ぐ構成としてもよい。 The present invention is not limited to the examples as long as the actions and effects of the present invention are exhibited. For example, just as the substantially truck-shaped closing member 92 is provided for the pipes 63 and 64, the closing member for which each of the pipes 61 and 62 is integrated may be provided. That is, a configuration may be configured in which a plurality of holes are closed by a single closing member.
