車両用空調装置のドア保持構造及びこれを備えた車両用空調装置Vehicle air conditioner door holding structure and vehicle air conditioner equipped with the same
 本発明は、2つのドアを同軸上で支持するために採用される車両用空調装置のドア保持構造とこのドア保持構造を備えた車両用空調装置に関する。 The present invention relates to a door holding structure for a vehicle air conditioner that is employed to support two doors on the same axis, and a vehicle air conditioner equipped with the door holding structure.

 車両用空調装置に用いられるドアは、軽量化を図るために樹脂製のドアが用いられるが、上述したドア構造においては、一方のドアの軸を他方のドアの軸の径方向の外側から挿入して仮組みする構成であるので、仮組みする際に、径方向の力のかけ具合によっては、被支持部(回転軸部)自体が径方向に撓んでしまい、円滑なドアの回転が阻害される恐れがあった。 The door used in the vehicle air conditioner is a resin door to reduce the weight, but in the door structure described above, the shaft of one door is inserted from the outside in the radial direction of the shaft of the other door. Therefore, when temporarily assembled, depending on how the radial force is applied, the supported portion (rotating shaft) itself is bent in the radial direction, and smooth rotation of the door is obstructed. There was a fear.
 本発明は、係る事情に鑑みてなされたものであり、仮組み時にドアの被支持部が径方向に撓むことを防ぎ、円滑なドアの回転を確保することが可能なドア保持構造と、これを備えた車両用空調装置を提供することを主たる課題としている。 The present invention has been made in view of such circumstances, a door holding structure capable of preventing the supported portion of the door from being bent in the radial direction during temporary assembly, and ensuring smooth rotation of the door; It is the main subject to provide a vehicle air conditioner provided with this.
 上記課題を達成するために、本発明にかかる車両用空調装置のドア保持構造は、回転軸線の径方向に力を加えないように2つのドアを仮組みする構成を提案するもので、対をなす第1の被支持部を備える第1ドアと、対をなす第2の被支持部を備える第2ドアとを有し、対向する第1の壁と第2の壁との間に前記第1ドアと前記第2ドアとが配置されるドア保持構造であって、前記第1の被支持部の一方は、前記第1の壁に形成された第1の軸受孔に回転可能に支持され、前記第2の被支持部の他方は、前記第2の壁に形成された第2の軸受孔に回転可能に支持されるドア保持構造において、前記第2の被支持部の一方は、前記第1の被支持部の一方に前記第1の軸受孔からの垂線に沿って支持され、前記第1の軸受孔の軸線を中心として回転可能であり、前記第1の被支持部の他方は、前記第2の被支持部の他方に前記第2の軸受孔からの垂線に沿って支持され、前記第2の軸受孔の軸線を中心として回転可能であることを特徴としている。 In order to achieve the above object, the door holding structure for a vehicle air conditioner according to the present invention proposes a configuration in which two doors are temporarily assembled so as not to apply a force in the radial direction of the rotation axis. A first door having a first supported portion formed and a second door having a second supported portion forming a pair, and the first door is disposed between the first wall and the second wall facing each other. A door holding structure in which one door and the second door are arranged, wherein one of the first supported portions is rotatably supported by a first bearing hole formed in the first wall. In the door holding structure in which the other of the second supported parts is rotatably supported by a second bearing hole formed in the second wall, one of the second supported parts is One of the first supported parts is supported along a perpendicular line from the first bearing hole, and the axis of the first bearing hole is the center. The other one of the first supported parts is supported along the perpendicular from the second bearing hole to the other of the second supported parts, and the axis of the second bearing hole is It is characterized by being rotatable as a center.
 このように、第1のドアと第2ドアとを仮組みする際に、第2の被支持部の一方を第1の被支持部の一方に第1の軸受孔からの垂線に沿って(第1の軸受孔の軸方向に沿って)支持させ、また、第1の被支持部の他方を第2の被支持部の他方に第2の軸受孔からの垂線に沿って(第2の軸受孔の軸方向に沿って)支持させるので、被支持部の径方向の外側から他の被支持部を挿入する必要がなく、ドアの被支持部が撓むことが防止される。 Thus, when temporarily assembling the first door and the second door, one of the second supported parts is connected to one of the first supported parts along the perpendicular line from the first bearing hole ( The other one of the first supported parts is supported along the perpendicular from the second bearing hole to the other of the second supported parts (second direction). Since it is supported (along the axial direction of the bearing hole), it is not necessary to insert another supported part from the outside in the radial direction of the supported part, and the supported part of the door is prevented from being bent.
 なお、第2の被支持部の一方を第1の被支持部の一方に第1の軸受孔からの垂線に沿って支持し、且つ、第1の被支持部の他方を、第2の被支持部の他方に第2の軸受孔からの垂線に沿って支持する構成としては、
 (1)第2の被支持部の一方を第1の被支持部の一方の内径側に挿入することで軸方向に沿って支持し、第1の被支持部の他方を第2の被支持部の他方の内径側に挿入することで軸方向に沿って支持するようにしても、
 (2)第2の被支持部の一方を第1の被支持部の一方の外径側に外装することで軸方向に沿って支持し、第1の被支持部の他方を第2の被支持部の他方の外径側に外装することで軸方向に沿って支持するようにしても、
 (3)第2の被支持部の一方を第1の被支持部の一方の内径側に挿入することで軸方向に沿って支持し、第1の被支持部の他方を第2の被支持部の他方の外径側に外装することで軸方向に沿って支持するようにしても、
 (4)第2の被支持部の一方を第1の被支持部の一方の外径側に外装することで軸方向に沿って支持し、第1の被支持部の他方を第2の被支持部の他方の内径側に挿入することで軸方向に沿って支持するようにしてもよい。
One of the second supported parts is supported by one of the first supported parts along the perpendicular from the first bearing hole, and the other of the first supported parts is supported by the second supported part. As a configuration to support along the perpendicular from the second bearing hole to the other support portion,
(1) One of the second supported parts is supported along the axial direction by being inserted into one inner diameter side of the first supported part, and the other of the first supported parts is supported as the second supported part. Even if it is supported along the axial direction by inserting the other inner diameter side of the part,
(2) One of the second supported parts is supported along the axial direction by covering one outer diameter side of the first supported part, and the other of the first supported parts is supported by the second supported part. Even if it is supported along the axial direction by covering the other outer diameter side of the support part,
(3) One of the second supported parts is supported along the axial direction by being inserted into one inner diameter side of the first supported part, and the other of the first supported parts is supported as the second supported part. Even if it is supported along the axial direction by covering the other outer diameter side of the part,
(4) One of the second supported parts is supported along the axial direction by covering one outer diameter side of the first supported part, and the other of the first supported parts is supported by the second supported part. You may make it support along an axial direction by inserting in the other internal diameter side of a support part.
 以上の構成は、第1ドアと第2ドアが、それぞれの被支持部に対して略垂直に延設される一対の側壁部と、この一対の側壁部の間を繋ぐ閉塞部とを有して構成されるロータリ式ドアであっても、それぞれの被支持部の軸線に対して略平行に延設された板状部を備える板ドアであっても同様に採用可能である。 In the above configuration, the first door and the second door have a pair of side wall portions that extend substantially perpendicular to the respective supported portions, and a blocking portion that connects between the pair of side wall portions. Even a rotary door configured as described above can be similarly adopted even if it is a plate door provided with a plate-like portion extending substantially parallel to the axis of each supported portion.
 特に、ロータリ式ドアを採用する場合には、前記一対の側壁部の間に、前記被支持部の近傍でリブを架設することが強度上好ましい。 In particular, when a rotary door is employed, it is preferable in terms of strength that a rib is provided between the pair of side wall portions in the vicinity of the supported portion.
 なお、このような構成を車両用空調装置に採用するには、前記第1の壁と前記第2の壁を、空気流路が内部に形成された空調ケースで構成し、前記第1ドアと前記第2ドアを、前記空気流路に配設するとよい。 In order to adopt such a configuration for a vehicle air conditioner, the first wall and the second wall are formed of an air conditioning case in which an air flow path is formed, and the first door and The second door may be disposed in the air flow path.
 以上述べたように、本発明によれば、対をなす第1の被支持部を備えた第1ドアと、対をなす第2の被支持部を備えた第2ドアとを同軸上で支持するにあたり、第2の被支持部の一方を第1の被支持部の一方に第1の軸受孔からの垂線に沿って回転可能に支持し、第1の被支持部の他方を、第2の被支持部の他方に第2の軸受孔からの垂線に沿って回転可能に支持するようにしたので、第1ドアと第2ドアとの仮組み時に、被支持部の径方向の外側から他の被支持部を挿入する必要がなく、それぞれの被支持部に径方向から力が加わることがなくなる。このため、被支持部が径方向に撓むことを防止することが可能となり、ドアの円滑な回転が阻害されることがなくなる。 As described above, according to the present invention, the first door having the first supported portion that makes a pair and the second door having the second supported portion that makes the pair are coaxially supported. In doing so, one of the second supported parts is supported by one of the first supported parts so as to be rotatable along a perpendicular line from the first bearing hole, and the other of the first supported parts is secondly supported. The other supported portion is supported so as to be rotatable along the vertical line from the second bearing hole, so that when the first door and the second door are temporarily assembled, from the outside in the radial direction of the supported portion. There is no need to insert other supported parts, and no force is applied to each supported part from the radial direction. For this reason, it is possible to prevent the supported portion from being bent in the radial direction, and the smooth rotation of the door is not hindered.
 なお、第1ドア及び第2ドアをロータリ式ドアで構成する場合において、一対の側壁部間に被支持部の近傍でリブを架設することで、側壁部に対して軸方向に力が加わった場合でもドアの撓みをなくし、被支持部が支持部から脱落することを防止することが可能となる。 In the case where the first door and the second door are composed of rotary doors, a force is applied in the axial direction to the side wall portion by installing a rib between the pair of side wall portions in the vicinity of the supported portion. Even in this case, it is possible to eliminate the bending of the door and prevent the supported portion from falling off the supporting portion.

However, in the present invention, the following four forms are adopted. Hereinafter, each form is explained in full detail.
 図2において、ドア保持構造の第1の実施例が示されている。この例において、ミックスドア20の第1の被支持部の一方21aは、側壁部22aから回転軸線上を空調ケース2の外側へ向けて円筒状に形成されるもので、ケース部材2b(第2の壁)と対向するケース部材2a(第1の壁)に形成された第1の軸受孔50aに回転自在に支持されている。また、第1の被支持部の他方21bは、側壁部22bから回転軸線上を空調ケース2の外側に向けて円柱状に形成されている。 FIG. 2 shows a first embodiment of the door holding structure.

The second bearing hole 50b formed in the (second wall) is rotatably supported.
 第2の被支持部の一方31aの外径は、第1の被支持部の一方21aに形成されている筒孔25aの内径よりも僅かに小さく形成されており、したがって、第2の被支持部の一方31aは、第1の被支持部の一方21aの筒孔25aに回転自在に挿入される。また、第1の被支持部の他方21bの外径は、第2の被支持部の他方31bに形成されている筒孔35bの内径よりも僅かに小さく形成されており、したがって、第1の被支持部の他方21bは、第2の被支持部の他方31bの筒孔35bに回転自在に挿入される。 The outer diameter of one of the second supported parts 31a is slightly smaller than the inner diameter of the cylindrical hole 25a formed in one of the first supported parts 21a. One of the parts 31a is rotatably inserted into the cylindrical hole 25a of the one 21a of the first supported part. In addition, the outer diameter of the other 21b of the first supported portion is formed slightly smaller than the inner diameter of the cylindrical hole 35b formed in the other 31b of the second supported portion. The other 21b of the supported part is rotatably inserted into the cylindrical hole 35b of the other 31b of the second supported part.
 第1の被支持部の一方21aの軸方向の長さは、第2の被支持部の一方31aの軸方向の長さよりも長く形成され、第2の被支持部の一方31aが挿入される筒孔25aの範囲は少なくとも断面円形に形成されている。また、第2の被支持部の他方31bの軸方向の長さは、第1の被支持部の他方21bの軸方向の長さよりも長く形成され、第1の被支持部の他方21bが挿入される筒孔35bの範囲は、少なくとも断面円形に形成されている The length in the axial direction of one side 21a of the first supported part is formed longer than the length in the axial direction of one side 31a of the second supported part, and one side 31a of the second supported part is inserted. The range of the cylindrical hole 25a is at least circular in cross section. In addition, the length in the axial direction of the other supported portion 31b of the second supported portion is longer than the length in the axial direction of the other supported portion 21b of the first supported portion, and the other 21b of the first supported portion is inserted. The range of the cylinder hole 35b to be formed is at least circular in cross section
 なお、51aは、空調ケース2の外側から第1の被支持部の一方21aに装着されてミックスドア20に回転動力を付与するレバー部材であり、51bは、空調ケース2の外側から第2の被支持部の他方31bに装着されてモードドア30に回転動力を付与するレバー部材である。 In addition, 51a is a lever member which is attached to one side 21a of the first supported portion from the outside of the air conditioning case 2 and applies rotational power to the mix door 20, and 51b is a second member from the outside of the air conditioning case 2. It is a lever member that is attached to the other supported portion 31 b and applies rotational power to the mode door 30.
 以上の構成において、ミックスドア20(第1ドア)とモードドア30(第2ドア)とを組み付けるには、図3(a)に示されるように、ミックスドア20とモードドア30とを互いの被支持部(第1の被支持部21a,21bと第2の被支持部31a,31b)を近接させるように対向させ、この状態からミックスドア20の被支持部(21a,21b)とモードドア30の被支持部(31a,31b)とが軸方向で一列となるように互いのドアを軸方向でずらした状態とし(図3(b))、しかる後に、一方のドア(モードドア30)を他方のドア(ミックスドア20)に軸方向で重ね合わせるように移動させて、第2の被支持部の一方31aを第1の被支持部の一方21aに軸方向に沿って近接させ、また、第2の被支持部の他方31bを第1の被支持部の他方21bに軸方向に沿って同方向から近接させる。 In the above configuration, to assemble the mix door 20 (first door) and the mode door 30 (second door), as shown in FIG. 3A, the mix door 20 and the mode door 30 are connected to each other. The supported parts (the first supported parts 21a, 21b and the second supported parts 31a, 31b) are opposed to each other, and from this state, the supported parts (21a, 21b) of the mix door 20 and the mode door The doors are shifted in the axial direction so that the 30 supported portions (31a, 31b) are aligned with each other in the axial direction (FIG. 3B), and then one of the doors (mode door 30). Is moved so as to overlap the other door (mixed door 20) in the axial direction, and one of the second supported parts 31a is brought close to one of the first supported parts 21a along the axial direction, and , The other of the second supported parts 3 The b along the axial direction to a first other 21b of the supported portion to close in the same direction.
 そして、第2の被支持部の一方31aを第1の被支持部の一方21aの筒孔25aに挿入し(第1の被支持部の一方21aを第2の被支持部の一方31aに外装し)、また、第2の被支持部の他方31bを第1の被支持部の他方21bに外装(第1の被支持部の他方21bを第2の被支持部の他方31bの筒孔35bに挿入)することで、ミックスドア20とモードドア30とを同軸線上で互いに回転可能に仮組みする(図3(c))。 Then, the one 31a of the second supported part is inserted into the cylindrical hole 25a of the one 21a of the first supported part (the one 21a of the first supported part is attached to the one 31a of the second supported part). In addition, the other 31b of the second supported portion is attached to the other 21b of the first supported portion, and the exterior (the other 21b of the first supported portion is connected to the cylindrical hole 35b of the other 31b of the second supported portion). 3), the mix door 20 and the mode door 30 are temporarily assembled so as to be rotatable with respect to each other on the coaxial line (FIG. 3C).
 その後、左右に2分割されたケース部材2a,2bを回転軸線方向の外側から近接させ、第1の被支持部の一方21aをケース部材2aの第1の軸受孔50aに挿入し、また、第2の被支持部の他方31bをケース部材2bの第2の軸受孔50bに挿入する(図3(d))。 Thereafter, the case members 2a and 2b divided into the left and right parts are brought close to each other from the outside in the rotation axis direction, and one of the first supported parts 21a is inserted into the first bearing hole 50a of the case member 2a. The other supported portion 31b of 2 is inserted into the second bearing hole 50b of the case member 2b (FIG. 3D).
 したがって、上述した構成によれば、ミックスドア20とモードドア30とを仮組みする際には、第2の被支持部の一方31aを第1の被支持部の一方21aに第1の軸受孔50aからの垂線に沿って(第1の軸受孔50aの軸方向に沿って)支持させ、また、第1の被支持部の他方21bを第2の被支持部の他方31bに第2の軸受孔50bからの垂線に沿って(第2の軸受孔50bの軸方向に沿って)支持させるので、第1の被支持部に対して第2の被支持部を径方向の外側から挿入する必要や、第2の被支持部に対して第1の被支持部を径方向の外側から挿入する必要がなく、それぞれの被支持部21a,21b,31a,31bに径方向から力が加わることがなくなる。このため、それぞれの被支持部21a,21b.31a,31bが径方向に撓むことが防止され、組み付け後において、ドアの円滑な回転が阻害されることがなくなる。 Therefore, according to the configuration described above, when the mix door 20 and the mode door 30 are temporarily assembled, the first bearing hole 31a is connected to the first supported portion one side 21a. The second bearing is supported along the perpendicular from 50a (along the axial direction of the first bearing hole 50a), and the other 21b of the first supported part is supported on the other 31b of the second supported part. Since it is supported along the vertical line from the hole 50b (along the axial direction of the second bearing hole 50b), it is necessary to insert the second supported part from the outside in the radial direction with respect to the first supported part. In addition, it is not necessary to insert the first supported portion from the outside in the radial direction with respect to the second supported portion, and a force is applied to each supported portion 21a, 21b, 31a, 31b from the radial direction. Disappear. For this reason, each supported part 21a, 21b. 31a and 31b are prevented from bending in the radial direction, and smooth rotation of the door is not hindered after assembly.
 また、ミックスドア20とモードドア30には、それぞれの被支持部21a,21b,31a,31bの近傍で一対の側壁部の間にリブ24,34が架設されているので、側壁部に対して軸方向に力が加わった場合でもドアの撓みをなくし、被支持部が支持部から脱落することを防止することが可能となる。 Moreover, since the ribs 24 and 34 are constructed between the pair of side wall portions in the vicinity of the supported portions 21a, 21b, 31a and 31b in the mix door 20 and the mode door 30, Even when a force is applied in the axial direction, it is possible to prevent the door from being bent and prevent the supported portion from falling off the support portion.
 図4において、ドア保持構造の第2の実施例が示されている。この例において、ミックスドア20の第1の被支持部の一方21aは、側壁部22aから回転軸線上を空調ケース2の外側及び内側に向けて円柱状に形成されるもので、外側に向けて形成された部分は、ケース部材2b(第2の壁)と対向するケース部材2a(第1の壁)に形成された第1の軸受孔50aに回転自在に支持されている。また、第1の被支持部の他方21bは、側壁部22bから回転軸線上に延設させないで、または、僅かに外側へ***させてボス部を形成し、そこに通孔25bを形成することによって構成されている。 FIG. 4 shows a second embodiment of the door holding structure. In this example, one side 21a of the first supported portion of the mix door 20 is formed in a columnar shape from the side wall portion 22a on the rotation axis toward the outside and the inside of the air conditioning case 2, and toward the outside. The formed portion is rotatably supported by a first bearing hole 50a formed in the case member 2a (first wall) facing the case member 2b (second wall). Further, the other 21b of the first supported portion does not extend from the side wall portion 22b onto the rotation axis, or is slightly raised outward to form a boss portion, and a through hole 25b is formed there. It is constituted by.
 モードドア30の第2の被支持部の一方31aは、側壁部32aから回転軸線上に何も延設されず、または僅かに外側へ***されてボス部を形成し、そこに通孔35aを形成することによって構成されている。また、第2の被支持部の他方31bは、側壁部32bから回転軸線上を空調ケース2の外側及び内側に向けて円柱状に形成され、ケース部材2a(第1の壁)と対向するケース部材2b(第2の壁)に形成された第2の軸受孔50bに回転自在に支持されている。 One of the second supported parts 31a of the mode door 30 is not extended on the rotation axis from the side wall part 32a, or is slightly raised outward to form a boss part, through which a through hole 35a is formed. It is configured by forming. Further, the other 31b of the second supported portion is formed in a columnar shape on the rotation axis from the side wall portion 32b toward the outside and inside of the air conditioning case 2, and faces the case member 2a (first wall). The second bearing hole 50b formed in the member 2b (second wall) is rotatably supported.
 第1の被支持部の一方21aの側壁部22aから内側に向けて形成された部分の外径は、第2の被支持部の一方31aに形成されている通孔35aの内径よりも僅かに小さく形成されており、したがって、第2の被支持部の一方31aは、第1の被支持部の一方21aに回転自在に外装される。また、第2の被支持部の他方31bの側壁部32bから内側に向けて形成された部分の外径は、第1の被支持部の他方21bに形成されている通孔25bの内径よりも僅かに小さく形成されており、したがって、第1の被支持部の他方21bは、第2の被支持部の他方31bに回転自在に外装される。 The outer diameter of the portion formed inward from the side wall portion 22a of the first supported portion 21a is slightly smaller than the inner diameter of the through hole 35a formed in the first supported portion 31a. Therefore, one of the second supported portions 31a is rotatably mounted on one of the first supported portions 21a. In addition, the outer diameter of the portion formed inward from the side wall portion 32b of the other 31b of the second supported portion is larger than the inner diameter of the through hole 25b formed in the other 21b of the first supported portion. Therefore, the other 21b of the first supported portion is rotatably mounted on the other 31b of the second supported portion.
 なお、51aは、空調ケース2の外側から第1の被支持部の一方21aに装着されてミックスドア20に回転動力を付与するレバー部材であり、51bは、空調ケース2の外側から第2の被支持部の他方31bに装着されてモードドア30に回転動力を付与するレバー部材である。 In addition, 51a is a lever member which is attached to one side 21a of the first supported portion from the outside of the air conditioning case 2 and applies rotational power to the mix door 20, and 51b is a second member from the outside of the air conditioning case 2. It is a lever member that is attached to the other supported portion 31 b and applies rotational power to the mode door 30.
 以上の構成において、ミックスドア20とモードドア30とを組み付けるには、図5(a)に示されるように、ミックスドア20とモードドア30とを互いの被支持部(第1の被支持部21a,21bと第2の被支持部31a,31b)を近接させるように対向させ、この状態からミックスドア20の被支持部(21a,21b)とモードドア30の被支持部(31a,31b)とが軸方向で一列となるように互いのドアを軸方向でずらした状態とし(図5(b))、しかる後に、一方のドア(モードドア30)を他方のドア(ミックスドア20)に軸方向で重ね合わせるように移動させて、第2の被支持部の一方31aを第1の被支持部の一方21aに軸方向に沿って近接させ、また、第2の被支持部の他方31bを第1の被支持部の他方21bに軸方向に沿って同方向から近接させる。 In the above configuration, in order to assemble the mix door 20 and the mode door 30, as shown in FIG. 5A, the mix door 20 and the mode door 30 are connected to each other supported portion (first supported portion). 21a, 21b and the second supported portions 31a, 31b) are made to face each other, and from this state, the supported portions (21a, 21b) of the mix door 20 and the supported portions (31a, 31b) of the mode door 30 The doors are shifted in the axial direction so that they are aligned in the axial direction (FIG. 5B), and then one door (mode door 30) is replaced with the other door (mixed door 20). The second supported part 31a is moved close to the first supported part 21a in the axial direction by being moved so as to overlap in the axial direction, and the second supported part 31b Other than the first supported part Along the axial direction to approach the same direction 21b.
 そして、第2の被支持部の一方31aを第1の被支持部の一方21aに外装し(第1の被支持部の一方21aを第2の被支持部の一方31aの通孔35aに挿入し)、また、第2の被支持部の他方31bを第1の被支持部の他方21bの通孔25bに挿入(第1の被支持部の他方21bを第2の被支持部の他方31bに外装)することで、ミックスドア20とモードドア30とを同軸線上で互いに回転可能に仮組みする(図5(c))。 Then, one of the second supported parts 31a is sheathed on one of the first supported parts 21a (the one 21a of the first supported part is inserted into the through hole 35a of the one 31a of the second supported part. In addition, the other 31b of the second supported portion is inserted into the through hole 25b of the other 21b of the first supported portion (the other 21b of the first supported portion is inserted into the other 31b of the second supported portion). The mix door 20 and the mode door 30 are temporarily assembled so as to be rotatable with respect to each other on the coaxial line (FIG. 5C).
 その後、左右に2分割されたケース部材2a,2bを回転軸線方向の外側から近接させ、第1の被支持部の一方21aをケース部材2aの第1の軸受孔50aに挿入し、第2の被支持部の他方31bをケース部材2bの第2の軸受孔50bに挿入する(図5(d))。 After that, the case members 2a and 2b divided into left and right are brought close to each other from the outside in the rotation axis direction, and one of the first supported portions 21a is inserted into the first bearing hole 50a of the case member 2a, and the second The other supported portion 31b is inserted into the second bearing hole 50b of the case member 2b (FIG. 5D).
 したがって、上述した構成においても、ミックスドア20とモードドア30とを仮組みする際には、第2の被支持部の一方31aを第1の被支持部の一方21aに第1の軸受孔50aからの垂線に沿って(第1の軸受孔50aの軸方向に沿って)支持させ、また、第1の被支持部の他方21bを第2の被支持部の他方31bに第2の軸受孔50bからの垂線に沿って(第2の軸受孔50bの軸方向に沿って)支持させるので、第1の被支持部に対して第2の被支持部を径方向の外側から挿入する必要や、第2の被支持部に対して第1の被支持部を径方向の外側から挿入する必要がなく、それぞれの被支持部21a,21b,31a,31bに径方向から力が加わることがなくなる。このため、それぞれの被支持部21a,21b,31a,31bが径方向に撓むことが防止され、組み付け後において、ドアの円滑な回転が阻害されることがなくなる。 Therefore, also in the above-described configuration, when the mix door 20 and the mode door 30 are temporarily assembled, the first bearing hole 50a is formed such that the one 31a of the second supported portion is connected to the one 21a of the first supported portion. Is supported along the vertical line (along the axial direction of the first bearing hole 50a), and the other 21b of the first supported part is supported on the other 31b of the second supported part by the second bearing hole. Since it is supported along the vertical line from 50b (along the axial direction of the second bearing hole 50b), it is necessary to insert the second supported portion from the outside in the radial direction with respect to the first supported portion. It is not necessary to insert the first supported portion from the outside in the radial direction with respect to the second supported portion, and no force is applied to each supported portion 21a, 21b, 31a, 31b from the radial direction. . For this reason, each supported part 21a, 21b, 31a, 31b is prevented from bending in the radial direction, and the smooth rotation of the door is not hindered after assembly.
 また、ミックスドア20とモードドア30には、それぞれの被支持部21a,21b,31a,31bの近傍で一対の側壁部の間にリブ24,34が架設されているので、側壁部に対して軸方向に力が加わった場合でもドアの撓みをなくし、被支持部が支持部から脱落することを防止することが可能となる。 Moreover, since the ribs 24 and 34 are constructed between the pair of side wall portions in the vicinity of the supported portions 21a, 21b, 31a and 31b in the mix door 20 and the mode door 30, Even when a force is applied in the axial direction, it is possible to prevent the door from being bent and prevent the supported portion from falling off the support portion.
 図6において、ドア保持構造の第3の実施例が示されている。この例において、ミックスドア20の第1の被支持部の一方21aは、側壁部22aから回転軸線上を空調ケース2の外側に向けて円筒状に形成されるもので、ケース部材2b(第2の壁)と対向するケース部材2a(第1の壁)に形成された第1の軸受孔50aに回転自在に支持されている。また、第1の被支持部の他方21bは、側壁部22bから回転軸線上に何も延設されず、または僅かに外側へ***されてボス部を形成し、そこに通孔25bを形成することによって構成されている。 FIG. 6 shows a third embodiment of the door holding structure. In this example, one of the first supported parts 21a of the mix door 20 is formed in a cylindrical shape from the side wall part 22a toward the outside of the air conditioning case 2 on the rotation axis, and the case member 2b (second And a first bearing hole 50a formed in the case member 2a (first wall) facing the wall. Also, the other 21b of the first supported portion is not extended from the side wall portion 22b on the rotation axis, or is slightly raised outward to form a boss portion, and a through hole 25b is formed there. Is made up of.
 モードドア30の第2の被支持部の一方31aは、側壁部32aから回転軸線上を空調ケース2の外側に向けて円柱状に形成されている。また、第2の被支持部の他方31bは、側壁部32bから回転軸線上を空調ケース2の外側及び内側に向けて円柱状に形成され、ケース部材2a(第1の壁)と対向するケース部材2b(第2の壁)に形成された第2の軸受孔50bに回転自在に支持されている。 One side 31 a of the second supported portion of the mode door 30 is formed in a columnar shape from the side wall portion 32 a toward the outside of the air conditioning case 2 on the rotation axis. Further, the other 31b of the second supported portion is formed in a columnar shape on the rotation axis from the side wall portion 32b toward the outside and inside of the air conditioning case 2, and faces the case member 2a (first wall). The second bearing hole 50b formed in the member 2b (second wall) is rotatably supported.
 第2の被支持部の一方31aの外径は、第1の被支持部の一方21aに形成されている筒孔25aの内径よりも僅かに小さく形成されており、したがって、第2の被支持部の一方31aは、第1の被支持部の一方21aの筒孔25aに回転自在に挿入される。ここで、第1の被支持部の一方21aの軸方向の長さは、第2の被支持部の一方31aの軸方向の長さよりも長く形成され、第2の被支持部の一方31aが挿入される筒孔25aの範囲は少なくとも断面円形に形成されている。 The outer diameter of one of the second supported parts 31a is slightly smaller than the inner diameter of the cylindrical hole 25a formed in one of the first supported parts 21a. One of the parts 31a is rotatably inserted into the cylindrical hole 25a of the one 21a of the first supported part. Here, the axial length of the first supported portion 21a is longer than the axial length of the second supported portion 31a, and the second supported portion 31a The range of the cylindrical hole 25a to be inserted is at least circular in cross section.
 また、第2の被支持部の他方31bの側壁部32bから内側に向けて形成された部分の外径は、第1の被支持部の他方21bに形成されている通孔25bの内径よりも僅かに小さく形成されており、したがって、第1の被支持部の他方21bは、第2の被支持部の他方31bに回転自在に外装される。 In addition, the outer diameter of the portion formed inward from the side wall portion 32b of the other 31b of the second supported portion is larger than the inner diameter of the through hole 25b formed in the other 21b of the first supported portion. Therefore, the other 21b of the first supported portion is rotatably mounted on the other 31b of the second supported portion.
 なお、51aは、空調ケース2の外側から第1の被支持部の一方21aに装着されてミックスドア20に回転動力を付与するレバー部材であり、51bは、空調ケース2の外側から第2の被支持部の他方31bに装着されてモードドア30に回転動力を付与するレバー部材である。 In addition, 51a is a lever member which is attached to one side 21a of the first supported portion from the outside of the air conditioning case 2 and applies rotational power to the mix door 20, and 51b is a second member from the outside of the air conditioning case 2. It is a lever member that is attached to the other supported portion 31 b and applies rotational power to the mode door 30.
 以上の構成において、ミックスドア20とモードドア30とを組み付けるには、図7(a)に示されるように、ミックスドア20とモードドア30とを互いの被支持部(第1の被支持部21a,21bと第2の被支持部31a,31b)を近接させるように対向させ、この状態からミックスドア20の被支持部(21a,21b)とモードドア30の被支持部(31a,31b)とが軸方向で一列となるように互いのドアを軸方向でずらした状態とし(図7(b))、しかる後に、一方のドア(モードドア30)を他方のドア(ミックスドア20)に軸方向で重ね合わせるように移動させて、第2の被支持部の一方31aを第1の被支持部の一方21aに軸方向に沿って近接させ、また、第2の被支持部の他方31bを第1の被支持部の他方21bに軸方向に沿って同方向から近接させる。 In the above configuration, in order to assemble the mix door 20 and the mode door 30, as shown in FIG. 7A, the mix door 20 and the mode door 30 are connected to each other supported portion (first supported portion). 21a, 21b and the second supported portions 31a, 31b) are made to face each other, and from this state, the supported portions (21a, 21b) of the mix door 20 and the supported portions (31a, 31b) of the mode door 30 The doors are shifted in the axial direction so that they are aligned in the axial direction (FIG. 7B), and then one door (mode door 30) is replaced with the other door (mixed door 20). The second supported part 31a is moved close to the first supported part 21a in the axial direction by being moved so as to overlap in the axial direction, and the second supported part 31b Other than the first supported part Along the axial direction to approach the same direction 21b.
 そして、第2の被支持部の一方31aを第1の被支持部の一方21aの筒孔25aに挿入し(第1の被支持部の一方21aを第2の被支持部の一方31aに外装し)、また、第2の被支持部の他方31bを第1の被支持部の他方21bの通孔25bに挿入(第1の被支持部の他方21bを第2の被支持部の他方31bに外装)することで、ミックスドア20とモードドア30とを同軸線上で互いに回転可能に仮組みする(図7(c))。 Then, the one 31a of the second supported part is inserted into the cylindrical hole 25a of the one 21a of the first supported part (the one 21a of the first supported part is attached to the one 31a of the second supported part). In addition, the other 31b of the second supported portion is inserted into the through hole 25b of the other 21b of the first supported portion (the other 21b of the first supported portion is inserted into the other 31b of the second supported portion). , The mix door 20 and the mode door 30 are temporarily assembled so as to be rotatable with respect to each other on the coaxial line (FIG. 7C).
 その後、左右に2分割されたケース部材2a,2bを回転軸線方向の外側から近接させ、第1の被支持部の一方21aをケース部材2aの第1の軸受孔50aに挿入し、第2の被支持部の他方31bをケース部材2bの第2の軸受孔50bに挿入する(図7(d))。 After that, the case members 2a and 2b divided into left and right are brought close to each other from the outside in the rotation axis direction, and one of the first supported portions 21a is inserted into the first bearing hole 50a of the case member 2a, and the second The other supported portion 31b is inserted into the second bearing hole 50b of the case member 2b (FIG. 7D).
 したがって、上述した構成においても、ミックスドア20とモードドア30とを仮組みする際には、第2の被支持部の一方31aを第1の被支持部の一方21aに第1の軸受孔50aからの垂線に沿って(第1の軸受孔50aの軸方向に沿って)支持させ、また、第1の被支持部の他方21bを第2の被支持部の他方31bに第2の軸受孔50bからの垂線に沿って(第2の軸受孔50bの軸方向に沿って)支持させるので、第1の被支持部に対して第2の被支持部を径方向の外側から挿入する必要や、第2の被支持部に対して第1の被支持部を径方向の外側から挿入する必要がなく、それぞれの被支持部21a,21b,31a,31bに径方向から力が加わることがなくなる。このため、それぞれの被支持部21a,21b,31a,31bが径方向に撓むことが防止され、組み付け後において、ドアの円滑な回転が阻害されることがなくなる。 Therefore, also in the above-described configuration, when the mix door 20 and the mode door 30 are temporarily assembled, the first bearing hole 50a is formed such that the one 31a of the second supported portion is connected to the one 21a of the first supported portion. Is supported along the vertical line (along the axial direction of the first bearing hole 50a), and the other 21b of the first supported part is supported on the other 31b of the second supported part by the second bearing hole. Since it is supported along the vertical line from 50b (along the axial direction of the second bearing hole 50b), it is necessary to insert the second supported portion from the outside in the radial direction with respect to the first supported portion. It is not necessary to insert the first supported portion from the outside in the radial direction with respect to the second supported portion, and no force is applied to each supported portion 21a, 21b, 31a, 31b from the radial direction. . For this reason, each supported part 21a, 21b, 31a, 31b is prevented from bending in the radial direction, and the smooth rotation of the door is not hindered after assembly.
 また、ミックスドア20とモードドア30には、それぞれの被支持部21a,21b,31a,31bの近傍で一対の側壁部の間にリブ24,34が架設されているので、側壁部に対して軸方向に力が加わった場合でもドアの撓みをなくし、被支持部が支持部から脱落することを防止することが可能となる。 Moreover, since the ribs 24 and 34 are constructed between the pair of side wall portions in the vicinity of the supported portions 21a, 21b, 31a and 31b in the mix door 20 and the mode door 30, Even when a force is applied in the axial direction, it is possible to prevent the door from being bent and prevent the supported portion from falling off the support portion.
 図8において、ドア保持構造の第4の実施例が示されている。この例において、ミックスドア20の第1の被支持部の一方21aは、側壁部22aから回転軸線上を空調ケース2の外側及び内側に向けて円柱状に形成されるもので、外側に向けて形成された部分は、ケース部材2b(第2の壁)と対向するケース部材2a(第1の壁)に形成された第1の軸受孔50aに回転自在に支持されている。また、第1の被支持部の他方21bは、側壁部22bから回転軸線上を空調ケース2の外側に向けて円柱状に形成されている。 FIG. 8 shows a fourth embodiment of the door holding structure. In this example, one side 21a of the first supported portion of the mix door 20 is formed in a columnar shape from the side wall portion 22a on the rotation axis toward the outside and the inside of the air conditioning case 2, and toward the outside. The formed portion is rotatably supported by a first bearing hole 50a formed in the case member 2a (first wall) facing the case member 2b (second wall). Further, the other 21b of the first supported portion is formed in a columnar shape from the side wall portion 22b toward the outside of the air conditioning case 2 on the rotation axis.
 モードドア30の第2の被支持部の一方31aは、側壁部32aから回転軸線上に何も延設されず、または僅かに外側へ***されてボス部を形成し、そこに通孔35aを形成することによって構成されている。また、第2の被支持部の他方31bは、側壁部32bから回転軸線上を空調ケース2の外側に向けて円筒状に形成され、ケース部材2a(第1の壁)と対向する他方のケース部材2b(第2の壁)に形成された第2の軸受孔50bに回転自在に支持されている。 One of the second supported parts 31a of the mode door 30 is not extended on the rotation axis from the side wall part 32a, or is slightly raised outward to form a boss part, through which a through hole 35a is formed. It is configured by forming. Further, the other 31b of the second supported portion is formed in a cylindrical shape from the side wall portion 32b toward the outside of the air conditioning case 2 on the rotation axis, and faces the case member 2a (first wall). The second bearing hole 50b formed in the member 2b (second wall) is rotatably supported.
 第1の被支持部の一方21aの側壁部22aから内側に向けて形成された部分の外径は、第2の被支持部の一方31aに形成されている通孔35aの内径よりも僅かに小さく形成されており、したがって、第2の被支持部の一方31aは、第1の被支持部の一方21aに回転自在に外装される。また、第1の被支持部の他方21bの外径は、第2の被支持部の他方31bに形成されている筒孔35bの内径よりも僅かに小さく形成されており、したがって、第1の被支持部の他方21bは、第2の被支持部の他方31bの筒孔35bに回転自在に挿入される。ここで、第2の被支持部の他方31bの軸方向の長さは、第1の被支持部の他方21bの軸方向の長さよりも長く形成され、第1の被支持部の他方21bが挿入される筒孔35bの範囲は、少なくとも断面円形に形成されている。 The outer diameter of the portion formed inward from the side wall portion 22a of the first supported portion 21a is slightly smaller than the inner diameter of the through hole 35a formed in the first supported portion 31a. Therefore, one of the second supported portions 31a is rotatably mounted on one of the first supported portions 21a. In addition, the outer diameter of the other 21b of the first supported portion is formed slightly smaller than the inner diameter of the cylindrical hole 35b formed in the other 31b of the second supported portion. The other 21b of the supported part is rotatably inserted into the cylindrical hole 35b of the other 31b of the second supported part. Here, the axial length of the other 31b of the second supported portion is formed longer than the axial length of the other 21b of the first supported portion, and the other 21b of the first supported portion is The range of the cylindrical hole 35b to be inserted is at least circular in cross section.
 なお、51aは、空調ケース2の外側から第1の被支持部の一方21aに装着されてミックスドア20に回転動力を付与するレバー部材であり、51bは、空調ケース2の外側から第2の被支持部の他方31bに装着されてモードドア30に回転動力を付与するレバー部材である。 In addition, 51a is a lever member which is attached to one side 21a of the first supported portion from the outside of the air conditioning case 2 and applies rotational power to the mix door 20, and 51b is a second member from the outside of the air conditioning case 2. It is a lever member that is attached to the other supported portion 31 b and applies rotational power to the mode door 30.
 以上の構成において、ミックスドア20とモードドア30とを組み付けるには、図9(a)に示されるように、ミックスドア20とモードドア30とを互いの被支持部(第1の被支持部21a,21bと第2の被支持部31a,31b)を近接させるように対向させ、この状態からミックスドア20の被支持部(21a,21b)とモードドア30の被支持部(31a,31b)とが軸方向で一列となるように互いのドアを軸方向でずらした状態とし(図9(b))、しかる後に、一方のドア(モードドア30)を他方のドア(ミックスドア20)に軸方向で重ね合わせるように移動させて、第2の被支持部の一方31aを第1の被支持部の一方21aに軸方向に沿って近接させ、また、第2の被支持部の他方31bを第1の被支持部の他方21bに軸方向に沿って同方向から近接させる。 In the above configuration, in order to assemble the mix door 20 and the mode door 30, as shown in FIG. 9A, the mix door 20 and the mode door 30 are connected to each other supported portion (first supported portion). 21a, 21b and the second supported portions 31a, 31b) are made to face each other, and from this state, the supported portions (21a, 21b) of the mix door 20 and the supported portions (31a, 31b) of the mode door 30 The doors are shifted in the axial direction so that they are aligned in the axial direction (FIG. 9B), and then one door (mode door 30) is replaced with the other door (mixed door 20). The second supported part 31a is moved close to the first supported part 21a in the axial direction by being moved so as to overlap in the axial direction, and the second supported part 31b Other than the first supported part Along the axial direction to approach the same direction 21b.
 そして、第2の被支持部の一方31aを第1の被支持部の一方21aに外装し(第1の被支持部の一方21aを第2の被支持部の一方31aの通孔35aに挿入し)、また、第2の被支持部の他方31bを第1の被支持部の他方21bに外装(第1の被支持部の他方21bを第2の被支持部の他方31bの筒孔35bに挿入)することで、ミックスドア20とモードドア30とを同軸線上で互いに回転可能に仮組みする(図9(c))。 Then, one side 31a of the second supported part is externally mounted on one side 21a of the first supported part (one side 21a of the first supported part is inserted into the through hole 35a of one side 31a of the second supported part. In addition, the other 31b of the second supported portion is placed on the other 21b of the first supported portion and the exterior (the other 21b of the first supported portion is replaced with the cylindrical hole 35b of the other 31b of the second supported portion). 9), the mix door 20 and the mode door 30 are temporarily assembled so as to be rotatable with respect to each other on a coaxial line (FIG. 9C).
 その後、左右に2分割されたケース部材2a,2bを回転軸線方向の外側から近接させ、第1の被支持部の一方21aをケース部材2aの第1の軸受孔50aに挿入し、第2の被支持部の他方31bをケース部材2bの第2の軸受孔50bに挿入する(図9(d))。 After that, the case members 2a and 2b divided into left and right are brought close to each other from the outside in the rotation axis direction, and one of the first supported portions 21a is inserted into the first bearing hole 50a of the case member 2a, and the second The other supported portion 31b is inserted into the second bearing hole 50b of the case member 2b (FIG. 9D).
 したがって、上述した構成においても、ミックスドア20とモードドア30とを仮組みする際には、第2の被支持部の一方31aを第1の被支持部の一方21aに第1の軸受孔50aからの垂線に沿って(第1の軸受孔50aの軸方向に沿って)支持させ、また、第1の被支持部の他方21bを第2の被支持部の他方31bに第2の軸受孔50bからの垂線に沿って(第2の軸受孔50bの軸方向に沿って)支持させるので、第1の被支持部に対して第2の被支持部を径方向の外側から挿入する必要や、第2の被支持部に対して第1の被支持部を径方向の外側から挿入する必要がなく、それぞれの被支持部21a,21b,31a,31bに径方向から力が加わることがなくなる。このため、それぞれの被支持部21a,21b.31a,31bが径方向に撓むことが防止され、組み付け後において、ドアの円滑な回転が阻害されることがなくなる。 Therefore, also in the above-described configuration, when the mix door 20 and the mode door 30 are temporarily assembled, the first bearing hole 50a is formed such that the one 31a of the second supported portion is connected to the one 21a of the first supported portion. Is supported along the vertical line (along the axial direction of the first bearing hole 50a), and the other 21b of the first supported part is supported on the other 31b of the second supported part by the second bearing hole. Since it is supported along the vertical line from 50b (along the axial direction of the second bearing hole 50b), it is necessary to insert the second supported portion from the outside in the radial direction with respect to the first supported portion. It is not necessary to insert the first supported portion from the outside in the radial direction with respect to the second supported portion, and no force is applied to each supported portion 21a, 21b, 31a, 31b from the radial direction. . For this reason, each supported part 21a, 21b. 31a and 31b are prevented from bending in the radial direction, and smooth rotation of the door is not hindered after assembly.
 また、ミックスドア20とモードドア30には、それぞれの被支持部21a,21b,
31a,31bの近傍で一対の側壁部の間にリブ24,34が架設されているので、側壁部に対して軸方向に力が加わった場合でもドアの撓みをなくし、被支持部が支持部から脱落することを防止することが可能となる。
Further, the mixed door 20 and the mode door 30 have respective supported portions 21a, 21b,
Since the ribs 24 and 34 are provided between the pair of side wall portions in the vicinity of 31a and 31b, even when force is applied to the side wall portion in the axial direction, the door is not bent, and the supported portion is the supporting portion. It is possible to prevent falling off.

 ここまでを、ミックスドア20(第1ドア)及びモードドア30(第2ドア)としてロータリ式ドアを用いた例で説明してきたが、ミックスドアとモードドアを、それぞれの被支持部の軸線に対して略平行に延設された板状部を備える板ドアで構成し、前述した被支持部の構成を同様に採用してもよい。 Up to this point, an example has been described in which rotary doors are used as the mix door 20 (first door) and the mode door 30 (second door). However, the mix door and the mode door are connected to the axis of each supported part. Alternatively, it may be configured by a plate door including a plate-like portion extending substantially in parallel, and the above-described configuration of the supported portion may be similarly adopted.
 また、ドアの保持構造を、冷却用熱交換器(エバポレータ7)と加熱用熱交換器(ヒータコア8)との2つの熱交換器を備えた空調ユニットに用いた例として説明してきたが、冷却用熱交換器を備えず加熱用熱交換のみを備え、この加熱用熱交換器をバイパスした導入空気と加熱用熱交換器を通過した空気とで温度調整する空調ユニットに用いてもよい。 Moreover, although the door holding structure has been described as an example used in an air conditioning unit including two heat exchangers, a cooling heat exchanger (evaporator 7) and a heating heat exchanger (heater core 8), It may be used in an air conditioning unit that is provided with only a heat exchange for heating without a heat exchanger for heating, and that adjusts the temperature with the introduced air that bypasses the heat exchanger for heating and the air that has passed through the heat exchanger for heating.
 さらに、上述においては、ヒータコア8としてエンジン冷却水を用いる温水式ヒータを用いた例を示したが、PTCヒータや、周知のヒートポンプによる放熱器に置き換えても、組み合わせて用いてもよい。 Furthermore, in the above description, an example in which a hot water heater using engine cooling water is used as the heater core 8 has been shown, but it may be replaced with a PTC heater or a heat radiator using a known heat pump, or may be used in combination.
