［アダプタダクト５０の構造］
図１に示すように、ＨＶＡＣ１の空気送出口１１とデフロスタダクト３０の空気受け入れ口３１（図８（ａ），図８（ｂ）参照）の間には樹脂製のアダプタダクト５０が介在している。図６（ａ），図６（ｂ），図７（ａ），図７（ｂ），図７（ｃ）に示すように、このアダプタダクト５０は、デフロスタダクト３０の空気受け入れ部３２に嵌合（内嵌、図８（ｂ）参照）する角筒状の上側空気流通部５１と、下端部に空気受け入れ口４９（図７（ｂ）参照）が形成された下側空気流通部５２とを備え、左ハンドル仕様のアダプタダクト５０と右ハンドル仕様のアダプタダクト５０が同一構造の共通部品に構成されている。 [Structure of adapter duct 50]
As shown in FIG. 1, an adapter duct 50 made of resin is interposed between the air delivery port 11 of the HVAC 1 and the air receiving port 31 of the defroster duct 30 (see FIGS. 8A and 8B). Yes. 6 (a), 6 (b), 7 (a), 7 (b), and 7 (c), the adapter duct 50 is fitted into the air receiving portion 32 of the defroster duct 30. An upper air circulation part 51 having a rectangular tube shape (internal fitting, see FIG. 8B), and a lower air circulation part 52 in which an air receiving port 49 (see FIG. 7B) is formed at the lower end part. The left-hand handle type adapter duct 50 and the right-hand handle type adapter duct 50 are configured as common parts having the same structure.

前記上側空気流通部５１は横断面において車両の左右方向（車幅方向）に長い長方形状に形成され、下側空気流通部５２は横断面において、車両の左右方向に長く、かつ、前記上側空気流通部５１に対して前記左右方向に位置ずれした長方形状に形成されている。このアダプタダクト５０は車両の左右方向に沿うように配置される。 The upper air circulation portion 51 is formed in a rectangular shape that is long in the left-right direction (vehicle width direction) of the vehicle in the transverse section, and the lower air circulation portion 52 is long in the left-right direction of the vehicle in the transverse section, and the upper air It is formed in a rectangular shape shifted in the left-right direction with respect to the flow part 51. The adapter duct 50 is arranged along the left-right direction of the vehicle.

詳しくは、下側空気流通部５２は下側開放の長方形の上下反転した皿状に形成され、下端部の周部からＨＶＡＣ１の空気送出口１１の開口周縁部に圧接するフランジ５３が張り出している。このフランジ５３とＨＶＡＣ１の開口周縁部との間に前記パッキン１０（図１参照）が介在する。また、下側空気流通部５２の周壁とフランジ５３の上面とに、周壁の周方向に間隔を空けて並ぶ複数の補強リブＬが架け渡されている。 Specifically, the lower air circulation part 52 is formed in a rectangular shape that is vertically opened and inverted vertically, and a flange 53 that presses from the peripheral part of the lower end part to the opening peripheral part of the air outlet 11 of the HVAC 1 projects. . The packing 10 (see FIG. 1) is interposed between the flange 53 and the opening peripheral edge of the HVAC 1. In addition, a plurality of reinforcing ribs L that are arranged at intervals in the circumferential direction of the peripheral wall are bridged between the peripheral wall of the lower air circulation portion 52 and the upper surface of the flange 53.

そして、下側空気流通部５２の上壁６０の長手方向一端部側の一部分を残して前記上壁６０に開口部を形成し、この開口部の周部から側壁５５を立ち上げて前記上側空気流通部５１が形成されている。これにより、上側空気流通部５１と下側空気流通部５２がアダプタダクト５０の長手方向（車両の左右方向）で位置ずれした状態になっている。位置ずれ量は、左ハンドル仕様のＨＶＡＣ１の空気送出口１１と右ハンドル仕様のＨＶＡＣ１の空気送出口１１との車両の左右方向での位置ずれ量と同一である。 Then, an opening is formed in the upper wall 60 leaving a part of one end side in the longitudinal direction of the upper wall 60 of the lower air circulation part 52, and the side wall 55 is raised from the peripheral part of the opening to raise the upper air A distribution part 51 is formed. Thereby, the upper air circulation part 51 and the lower air circulation part 52 are in a state of being displaced in the longitudinal direction of the adapter duct 50 (the left-right direction of the vehicle). The amount of displacement is the same as the amount of displacement in the left-right direction of the vehicle between the air outlet 11 of the left-hand handle HVAC 1 and the air outlet 11 of the right-handle HVAC 1.

上側空気流通部５１と下側空気流通部５２の長手方向に沿う一対の内面間には、上側ほど上側空気流通部５１及び下側空気流通部５２の長手方向他端部側に位置するように傾斜した複数のフィン５４が架設されている。このフィン５４は運転席側に空気をガイドする。このフィン５４で運転席側に空気をガイドすることで、左ハンドル仕様のＨＶＡＣ１が車両の左右中心Ｏに対して右側に位置ずれしていることに起因する送風口の風量の左右不均等と、右ハンドル仕様のＨＶＡＣ１が車両の左右中心Ｏに対して左側に位置ずれしていることに起因する送風口の風量の左右不均等とを抑制して、前記風量を左右で均等にしやすくすることができる。 Between the pair of inner surfaces along the longitudinal direction of the upper air circulation part 51 and the lower air circulation part 52, the upper air circulation part 51 and the lower air circulation part 52 are positioned closer to the other end in the longitudinal direction of the upper air circulation part 51 and the lower air circulation part 52. A plurality of inclined fins 54 are installed. This fin 54 guides air to the driver's seat side. By guiding the air to the driver's seat side with this fin 54, the left and right HVAC 1 of the left handle specification is displaced to the right side with respect to the left and right center O of the vehicle, It is possible to make the air volume easy to equalize on the left and right sides by suppressing the left and right non-uniformity in the air volume of the air blowing port due to the right-hand drive specification HVAC 1 being displaced to the left with respect to the left and right center O of the vehicle. it can.

図３（ａ），図６（ｂ），図７（ａ）に示すように、アダプタダクト５０の長手方向に沿う一対の側壁の外面に複数の嵌合凸部５６が形成されている。この嵌合凸部５６はデフロスタダクト３０の空気受け入れ部３２の下端部に形成された前記嵌合凹部３５に下側から挿入して弾性嵌合する。図６（ｂ），図７（ａ）の符号５６Ｈは嵌合凸部５６を形成する型部分を抜いて形成された型抜き孔である。 As shown in FIGS. 3A, 6 B, and 7 A, a plurality of fitting convex portions 56 are formed on the outer surfaces of the pair of side walls along the longitudinal direction of the adapter duct 50. The fitting convex portion 56 is inserted into the fitting concave portion 35 formed at the lower end portion of the air receiving portion 32 of the defroster duct 30 from below and is elastically fitted. Reference numeral 56 H in FIGS. 6B and 7 A is a die-cutting hole formed by removing a mold portion that forms the fitting convex portion 56.

図６（ｂ），図７（ａ），図７（ｂ），図７（ｃ）に示すように、アダプタダクト５０の幅方向の一端部に、アダプタダクト５０の幅方向外側に突出する一対の第１係合爪５７（第１係合部に相当）が設けられ、幅方向の他端部に、アダプタダクト５０の幅方向外側に突出する一対の第２係合爪５８（第２係合部に相当）が設けられている。一対の第１係合爪５７と一対の第２係合爪５８はアダプタダクト５０の長手方向の端部側に位置している。一対の第１係合爪５７の間隔Ａ１と一対の第２係合爪５８の間隔Ｂ１は異なり、一対の第１係合爪５７の間隔Ａ１が一対の第２係合爪５８の間隔Ｂ１よりも短く設定されている。 6 (b), 7 (a), 7 (b), and 7 (c), a pair that protrudes outward in the width direction of the adapter duct 50 at one end portion in the width direction of the adapter duct 50. The first engagement claws 57 (corresponding to the first engagement portion) are provided, and a pair of second engagement claws 58 (second engagement) projecting outward in the width direction of the adapter duct 50 are provided at the other end portion in the width direction. Equivalent to the joint). The pair of first engaging claws 57 and the pair of second engaging claws 58 are located on the end side in the longitudinal direction of the adapter duct 50. The distance A1 between the pair of first engagement claws 57 and the distance B1 between the pair of second engagement claws 58 are different, and the distance A1 between the pair of first engagement claws 57 is greater than the distance B1 between the pair of second engagement claws 58. Is also set short.

前記一対の第１係合爪５７と第２係合爪５８は、前記上壁６０とフランジ５３の上面に一体に設けられた平面視コの字状の支持壁５９からアダプタダクト５０の幅方向外側に突出している。アダプタダクト５０の長手方向他端部側の支持壁５９の端部は前記上側空気流通部５１を構成する側壁５５に連なっている。また、アダプタダクト５０の長手方向一端部側の支持壁５９の端部は、アダプタダクト５０の上壁６０の上面に連なっている。これらの構造により、第１係合爪５７と第２係合爪５８の剛性・強度を向上させることができる。 The pair of first engaging claws 57 and the second engaging claws 58 are arranged in the width direction of the adapter duct 50 from a U-shaped support wall 59 provided integrally on the upper surfaces of the upper wall 60 and the flange 53. Projects outward. The end of the support wall 59 on the other end side in the longitudinal direction of the adapter duct 50 is connected to the side wall 55 that constitutes the upper air circulation part 51. Further, the end portion of the support wall 59 on the one end side in the longitudinal direction of the adapter duct 50 is continuous with the upper surface of the upper wall 60 of the adapter duct 50. With these structures, the rigidity and strength of the first engagement claw 57 and the second engagement claw 58 can be improved.

アダプタダクト５０の一対の第１係合爪５７は、左ハンドル仕様のベントダクト４０の一対の第１係合孔４５に各別に係合し、アダプタダクト５０の一対の第２係合爪５８は、右ハンドル仕様のベントダクト４０の一対の第２係合孔４６に各別に係合する。前述のように、一対の第１係合爪５７同士の間隔Ａ１と一対の第２係合爪５８同士の間隔Ｂ１が異なるとともに、一対の第１係合孔４５の間隔Ａ２と一対の第２係合孔４６の間隔Ｂ２とが異なって、一対の第１係合爪５７と一対の第２係合孔４６とが係合不可能に構成され、一対の第２係合爪５８と一対の第１係合孔４５とが係合不可能に構成されているから、左ハンドル仕様のベントダクト４０と右ハンドル仕様のベントダクト４０を取り違えで誤組み付けすることを防止することができる。 The pair of first engaging claws 57 of the adapter duct 50 are individually engaged with the pair of first engaging holes 45 of the vent duct 40 of the left handle specification, and the pair of second engaging claws 58 of the adapter duct 50 are The pair of second engagement holes 46 of the vent duct 40 of the right handle specification are individually engaged. As described above, the distance A1 between the pair of first engagement claws 57 is different from the distance B1 between the pair of second engagement claws 58, and the distance A2 between the pair of first engagement holes 45 and the pair of second engagement holes 45. Unlike the interval B2 between the engagement holes 46, the pair of first engagement claws 57 and the pair of second engagement holes 46 are configured to be unengageable. Since the first engagement hole 45 is configured so that it cannot be engaged, it is possible to prevent the left handle vent duct 40 and the right handle vent duct 40 from being mistakenly assembled.

図９（ａ），図９（ｂ）に示すように、前記アダプタダクト５０は、左ハンドル仕様の場合にはデフロスタダクト３０の空気受け入れ口３１の軸芯Ｑ周りの第１位置Ｄ１に位置し（図９（ａ））、右ハンドル仕様の場合には前記第１位置Ｄ１から前記軸芯Ｑ周りに１８０度（設定角度に相当）回転した第２位置Ｄ２に位置して（図９（ｂ））、いずれの仕様の場合もアダプタダクト５０の空気受け入れ口４９がＨＶＡＣ１の空気送出口１１に重なるよう構成されている。 As shown in FIGS. 9A and 9B, the adapter duct 50 is located at the first position D1 around the axis Q of the air receiving port 31 of the defroster duct 30 in the case of the left handle specification. (FIG. 9 (a)), in the case of the right handle specification, it is located at a second position D2 rotated by 180 degrees (corresponding to a set angle) around the axis Q from the first position D1 (FIG. 9 (b)). In any case, the air receiving port 49 of the adapter duct 50 is configured to overlap the air sending port 11 of the HVAC 1.

［左ハンドル仕様のＨＶＡＣ１とデフロスタダクト３０とベントダクト４０の組み付け］
図３（ａ）に示すように、アダプタダクト５０の長手方向の一端部を車両の右側に位置させるとともに他端部を左側に位置させて、アダプタダクト５０の上側空気流通部５１をデフロスタダクト３０の空気受け入れ部３２に嵌合させる（図８（ｂ）参照）。また、アダプタダクト５０の複数の嵌合凸部５６を、デフロスタダクト３０の空気受け入れ部３２の下端部に形成された複数の嵌合凹部３５に下側から挿入させて弾性嵌合させる。さらに、一対の第１係合爪５７（図６（ｂ），図７（ｂ）参照）を、左ハンドル仕様のベントダクト４０の背部の下端部に形成された一対の第１係合孔４５に車両前後方向で係合させる。これにより、デフロスタダクト３０・アダプタダクト５０・ベントダクト４０が互いに連結する。 [Assembly of left-hand drive HVAC1, defroster duct 30 and vent duct 40]

In the vehicle longitudinal direction. Thereby, the defroster duct 30, the adapter duct 50, and the vent duct 40 are connected to each other.

左ハンドル仕様のベントダクト４０の車両の左右中心Ｏに対するオフセット量と、右ハンドル仕様のベントダクト４０の車両の左右中心Ｏに対するオフセット量とは小さくて、一方の仕様のベントダクト４０を他方の仕様のベントダクト４０と取り違えて誤組み付けしてしまうことが考えられるが、前記一対の第１係合爪５７は、右ハンドル仕様のベントダクト４０の背部に形成された一対の第２係合孔４６には係合不可能であるので、上記の誤組み付けを防止することができる。 The offset amount of the left-hand handle vent duct 40 with respect to the left-right center O of the vehicle and the offset amount of the right-hand handle vent duct 40 with respect to the left-right center O of the vehicle are small. However, the pair of first engagement claws 57 may be paired with the second engagement holes 46 formed in the back portion of the right-hand handle vent duct 40. Can not be engaged, so that the above-described erroneous assembly can be prevented.
