The shaft portion of the left fixing bolt 17b is inserted through the left bolt insertion hole 17a and screwed into the left bolt hole 19a formed in the left fixing base 19 (see FIG. 3A) fixed to the housing 2. there is Thereby, the left heat exchanger fixing portion 16 is fixed to the housing 2 . The shaft portion of the left fixing bolt 17b extends rearward and upward.
　左側仮止部１８は、左側仮止孔１８ａが２つ形成されている。２つの左側仮止孔１８ａは、前後方向及び上下方向に離間して配置されている。各左側仮止孔１８ａには、左側壁部７から突出する左側仮止ボルト１８ｂが挿通している。各左側仮止ボルト１８ｂは、いわゆる段付きネジとされている。すなわち、各左側仮止ボルト１８ｂは、ネジ部と頭部との間に、ネジが切られていない円柱状の段部が設けられている。各左側仮止孔１８ａの直径は、左側仮止ボルト１８ｂの頭部及び段部の直径よりも大きい。 The left temporary fixing portion 18 is formed with two left temporary fixing holes 18a. The two left temporary fixing holes 18a are spaced apart in the front-rear direction and the vertical direction. A left temporary fixing bolt 18b protruding from the left side wall portion 7 is inserted through each left temporary fixing hole 18a. Each left temporary fixing bolt 18b is a so-called stepped screw. That is, each left temporary bolt 18b is provided with an unthreaded columnar stepped portion between the threaded portion and the head portion. The diameter of each left temporary fixing hole 18a is larger than the diameter of the head and stepped portion of the left temporary fixing bolt 18b.
　また、右側仮止部１４と左側仮止部１８とは、熱交換部１０の幅方向の重心を挟むように設けられている。すなわち、右側仮止部１４は、熱交換部１０の重心よりも右側に位置し、左側係止部は、熱交換部１０の重心よりも左側に位置している。 In addition, the right temporary fixing portion 14 and the left temporary fixing portion 18 are provided so as to sandwich the center of gravity of the heat exchange section 10 in the width direction. That is, the right temporary fixing portion 14 is positioned on the right side of the center of gravity of the heat exchanging portion 10 , and the left locking portion is positioned on the left side of the center of gravity of the heat exchanging portion 10 .
　次に、熱交換部１０を筐体２に固定する方法について説明する。
　まず、図４Ａに示すように、左側壁部７に設けられた左側仮止ボルト１８ｂに対して、左側仮止部１８に形成された左側仮止孔１８ａを挿通させる。この時、図４Ｂに示すように、２本の左側仮止ボルト１８ｂが、各々、左側仮止孔１８ａを挿通するようにする。このようにして、まず、熱交換器１１の左側を筐体２に対して仮止めする（保持工程）。 Next, a method for fixing the heat exchange section 10 to the housing 2 will be described.
First, as shown in FIG. 4A , the left temporary fixing bolt 18 b provided on the left side wall portion 7 is inserted into the left temporary fixing hole 18 a formed in the left temporary fixing portion 18 . At this time, as shown in FIG. 4B, the two left temporary fixing bolts 18b are inserted through the left temporary fixing holes 18a. In this manner, first, the left side of the heat exchanger 11 is temporarily fixed to the housing 2 (holding step).
　次に、右側壁部６に設けられた右側仮止ボルト１４ｂに対して、右側仮止部１４に形成された右側仮止孔１４ａを挿通させる。このとき、熱交換器１１の左側が２点で仮止めされているため、幅方向の軸を中心とした熱交換器１１の回転が抑制される。このため、作業員は、容易に右側仮止ボルト１４ｂに対して、右側仮止孔１４ａを挿通させることができる。このようにして、熱交換器１１の右側も筐体２に対して仮止めする（保持工程）。 Next, the right temporary fixing hole 14 a formed in the right temporary fixing portion 14 is inserted into the right temporary fixing bolt 14 b provided on the right side wall portion 6 . At this time, since the left side of the heat exchanger 11 is temporarily fixed at two points, rotation of the heat exchanger 11 about the axis in the width direction is suppressed. Therefore, the worker can easily insert the right temporary fixing hole 14a into the right temporary fixing bolt 14b. In this manner, the right side of the heat exchanger 11 is also temporarily fixed to the housing 2 (holding step).
　熱交換部１０が仮止めされると、作業員が熱交換部１０を支持していない状態となった場合であっても、左側仮止孔１８ａの下縁が左側仮止ボルト１８ｂを下方から支持するとともに、右側仮止孔１４ａの下縁が右側仮止ボルト１４ｂを下方から支持する。したがって、熱交換部１０が筐体２に対して保持された状態（仮止めされた状態）が維持される。また、この状態では、熱交換部１０の幅方向の移動が、左側係止部と左側壁部７の干渉及び右側係止部と右側壁部６との干渉によって、規制されている。また、右側仮止孔１４ａ及び左側仮止孔１８ａの直径は、左側仮止ボルト１８ｂの段部及び右側仮止ボルト１４ｂの段部の直径よりも大きく形成されている。すなわち、左側仮止ボルト１８ｂ及び右側仮止ボルト１４ｂは、挿通する各仮止孔との間に形成される隙間分だけ移動可能とされている。 When the heat exchange section 10 is temporarily fixed, even if the worker does not support the heat exchange section 10, the lower edge of the left temporary fixing hole 18a will be able to push the left temporary fixing bolt 18b from below. In addition to supporting the right temporary fixing bolt 14b, the lower edge of the right temporary fixing hole 14a supports the right temporary fixing bolt 14b from below. Therefore, the state in which the heat exchange unit 10 is held with respect to the housing 2 (the state in which it is temporarily fixed) is maintained. Further, in this state, the movement of the heat exchange portion 10 in the width direction is restricted by the interference between the left locking portion and the left side wall portion 7 and the interference between the right locking portion and the right side wall portion 6 . The diameters of the right temporary fixing hole 14a and the left temporary fixing hole 18a are formed to be larger than the diameters of the steps of the left temporary fixing bolt 18b and the right temporary fixing bolt 14b. That is, the left temporary bolt 18b and the right temporary bolt 14b are movable by the gap formed between the temporary bolts 18b and 14b through which they are inserted.
　左右両方の仮止めが完了すると、熱交換部１０を筐体２側の部材（本実施形態では右側固定台１５及び左側固定台１９）に固定する作業を行う。具体的には、まず、図２Ｃに示すように、左側固定部１７を左側固定台１９の方向へ移動させ、左側ボルト挿通孔１７ａと左側ボルト孔１９ａとを合わせる。この状態で、左側ボルト挿通孔１７ａに左側固定ボルト１７ｂを挿通するとともに、左側ボルト孔１９ａに左側固定ボルト１７ｂを螺合させる。次に、図２Ｄに示すように、右側固定部１３を右側固定台１５の方向へ移動させ、右側ボルト挿通孔１３ａと右側ボルト孔１５ａとを合わせる。この状態で、右側ボルト挿通孔１３ａに右側固定ボルト１３ｂを挿通するとともに、右側ボルト孔１５ａに右側固定ボルト１３ｂを螺合させる（固定工程）。
　以上のように、左側固定部１７及び右側固定部１３が筐体２に対して固定されることで、熱交換部１０が筐体２に固定される（図２Ａ及び図２Ｂ参照）。なお、熱交換部１０が筐体２に固定された状態では、仮止めが解除されている。 When both the left and right sides are temporarily fixed, the work of fixing the heat exchange section 10 to the members on the housing 2 side (in this embodiment, the right fixing base 15 and the left fixing base 19) is carried out. Specifically, first, as shown in FIG. 2C, the left fixing portion 17 is moved toward the left fixing base 19, and the left bolt insertion holes 17a and the left bolt holes 19a are aligned. In this state, the left fixing bolt 17b is inserted into the left bolt insertion hole 17a, and the left fixing bolt 17b is screwed into the left bolt hole 19a. Next, as shown in FIG. 2D, the right fixing portion 13 is moved toward the right fixing table 15, and the right bolt insertion hole 13a and the right bolt hole 15a are aligned. In this state, the right fixing bolt 13b is inserted into the right bolt insertion hole 13a, and the right fixing bolt 13b is screwed into the right bolt hole 15a (fixing step).
As described above, the heat exchange section 10 is fixed to the housing 2 by fixing the left fixing section 17 and the right fixing section 13 to the housing 2 (see FIGS. 2A and 2B). Note that the temporary fixing is released when the heat exchange unit 10 is fixed to the housing 2 .

　次に、ファンモータ２０を筐体２に固定する方法について説明する。
　まず、湾曲部３０上にファンモータ２０を乗せ、湾曲部３０とファンモータ２０をボルト等で固定する。次に、図７Ａに示すように、固定ブラケット２４の湾曲部３０に設けられたスリットと爪部２８とを係止させる。このとき、図７Ａ及び図７Ｂに示すように、モータ仮止ボルト３６に対して、モータ仮止部３２に形成されたモータ仮止孔３２ａが挿通されていない。次に、図８Ａに示すように、モータ仮止ボルト３６に対して、モータ仮止部３２に形成されたモータ仮止孔３２ａを挿通させる。この時、図８Ｂに示すように、モータ仮止ボルト３６に対して、モータ仮止孔３２ａの大孔部３２ａａを挿通させる。そして、作業員がモータを支持していない状態とすると、重力によって、モータ仮止部３２が下方に移動する。これによって、図９Ａ及び図９Ｂに示すように、モータ仮止ボルト３６がモータ仮止孔３２ａの小孔部３２ａｂへ移動する。
　このようにして、ファンモータ２０を筐体２に対して仮止めする。 Next, a method for fixing the fan motor 20 to the housing 2 will be described.
First, the fan motor 20 is placed on the curved portion 30, and the curved portion 30 and the fan motor 20 are fixed with bolts or the like. Next, as shown in FIG. 7A, the slit provided in the curved portion 30 of the fixed bracket 24 and the claw portion 28 are engaged. At this time, as shown in FIGS. 7A and 7B , the temporary motor fixing holes 32 a formed in the temporary motor fixing portion 32 are not inserted into the temporary motor fixing bolts 36 . Next, as shown in FIG. 8A , the motor temporary fixing holes 32 a formed in the motor temporary fixing portions 32 are inserted into the motor temporary fixing bolts 36 . At this time, as shown in FIG. 8B, the motor temporary fixing bolt 36 is inserted through the large hole portion 32aa of the motor temporary fixing hole 32a. When the operator does not support the motor, the motor temporary fixing portion 32 moves downward due to gravity. As a result, the motor temporary fixing bolt 36 moves to the small hole portion 32ab of the motor temporary fixing hole 32a, as shown in FIGS. 9A and 9B.
Thus, the fan motor 20 is temporarily fixed to the housing 2 .
　ファンモータ２０が仮止めされると、モータ仮止ボルト３６が、モータ仮止部３２を介して、ファンモータ２０を支持する。したがって、ファンモータ２０が筐体２に対して保持された状態（仮止めされた状態）が維持される。また、この状態では、モータ仮止ボルト３６がモータ仮止孔３２ａの小孔部３２ａｂと係合しているため、ファンモータ２０の幅方向の移動が規制されている。また、小孔部３２ａｂの下方は、大孔部３２ａａと連通しているので、モータ仮止部３２の上方へは移動可能とされている。 When the fan motor 20 is temporarily fixed, the motor temporary fixing bolt 36 supports the fan motor 20 via the motor temporary fixing portion 32 . Therefore, the state in which the fan motor 20 is held with respect to the housing 2 (the state in which it is temporarily fixed) is maintained. Further, in this state, the motor temporary fixing bolt 36 is engaged with the small hole portion 32ab of the motor temporary fixing hole 32a, so that the movement of the fan motor 20 in the width direction is restricted. Further, since the lower portion of the small hole portion 32ab communicates with the large hole portion 32aa, the motor temporary fixing portion 32 can be moved upward.
　仮止めが完了すると、ファンモータ２０を筐体２側の部材（本実施形態ではモータブラケット２３のモータ螺合部２９）に固定する作業を行う。具体的には、図６Ｂ及び図６Ｃに示すように、モータ固定部３１を上方へ移動させ、ボルト挿通孔３１ａとモータ固定用ボルト孔２９ａとを合わせる。この状態で、ボルト挿通孔３１ａにモータ固定ボルト３１ｂを挿通するとともに、モータ固定用ボルト孔２９ａにモータ固定ボルト３１ｂを螺合させる。
　以上のように、モータ固定部３１が筐体２に対して固定されることで、ファンモータ２０が筐体２に対して固定される（図６Ａから図６Ｃ参照）。なお、ファンモータ２０が筐体２に固定された状態では、仮止めが解除されている。 When the temporary fixing is completed, the operation of fixing the fan motor 20 to the member on the housing 2 side (in this embodiment, the motor screw portion 29 of the motor bracket 23) is performed. Specifically, as shown in FIGS. 6B and 6C, the motor fixing portion 31 is moved upward to align the bolt insertion hole 31a with the motor fixing bolt hole 29a. In this state, the motor fixing bolt 31b is inserted into the bolt insertion hole 31a, and the motor fixing bolt 31b is screwed into the motor fixing bolt hole 29a.
As described above, the fan motor 20 is fixed to the housing 2 by fixing the motor fixing portion 31 to the housing 2 (see FIGS. 6A to 6C). In addition, when the fan motor 20 is fixed to the housing 2, the temporary fixing is released.
　本実施形態によれば、以下の作用効果を奏する。
　本実施形態では、熱交換部１０及びファンモータ２０を固定するためのボルト（右側仮止ボルト１４ｂや、モータ固定ボルト３１ｂ等）の軸方向の移動を許容するように、熱交換部１０及びファンモータ２０を保持（仮止め）可能な仮止部（左側仮止部１８やモータ仮止部３２）を備えている。 According to this embodiment, the following effects are obtained.
In the present embodiment, the heat exchange unit 10 and the fan motor 20 are arranged so as to allow axial movement of the bolts (the right temporary bolt 14b, the motor fixing bolt 31b, etc.) for fixing the heat exchange unit 10 and the fan motor 20. A temporary fixing portion (the left temporary fixing portion 18 and the motor temporary fixing portion 32) capable of holding (temporarily fixing) the motor 20 is provided.
　これにより、熱交換部１０及びファンモータ２０を保持させた状態で、熱交換部１０及びファンモータ２０をボルト（右側仮止ボルト１４ｂや、モータ固定ボルト３１ｂ等）とともに軸方向に移動させて筐体２側に固定することができる。したがって、熱交換部１０及びファンモータ２０を固定する際に、作業者が熱交換部１０及びファンモータ２０を支持する必要がない。よって、熱交換部１０及びファンモータ２０の固定作業を容易化することができる。 As a result, while the heat exchange unit 10 and the fan motor 20 are held, the heat exchange unit 10 and the fan motor 20 are moved in the axial direction together with the bolts (the right temporary bolt 14b, the motor fixing bolt 31b, etc.) to move the housing. It can be fixed on the body 2 side. Therefore, when fixing the heat exchange section 10 and the fan motor 20, the operator does not need to support the heat exchange section 10 and the fan motor 20. FIG. Therefore, the fixation work of the heat exchange section 10 and the fan motor 20 can be facilitated.
　また、本実施形態では、仮止部（左側仮止部１８やモータ仮止部３２）が、熱交換部１０及びファンモータ２０を固定するためのボルト（右側仮止ボルト１４ｂや、モータ固定ボルト３１ｂ等）の軸方向と交差する交差方向の移動を規制するように熱交換部１０及びファンモータ２０を保持可能とされている。これにより、熱交換部１０及びファンモータ２０を固定する際に、交差方向の移動が規制される。よって、ボルト（右側仮止ボルト１４ｂや、モータ固定ボルト３１ｂ等）の交差方向の位置決めを行うことができる。したがって、容易にボルト（右側仮止ボルト１４ｂや、モータ固定ボルト３１ｂ等）を軸方向へ移動させることができるので、熱交換部１０及びファンモータ２０の固定作業を容易化することができる。 Further, in the present embodiment, the temporary fixing portions (the left temporary fixing portion 18 and the motor temporary fixing portion 32) are provided with bolts (the right temporary fixing bolt 14b and the motor fixing bolt) for fixing the heat exchange portion 10 and the fan motor 20. 31b, etc.) can hold the heat exchange section 10 and the fan motor 20 so as to restrict the movement in the direction crossing the axial direction. As a result, movement in the cross direction is restricted when fixing the heat exchange section 10 and the fan motor 20 . Therefore, the bolts (right temporary bolt 14b, motor fixing bolt 31b, etc.) can be positioned in the cross direction. Therefore, since the bolts (right temporary bolt 14b, motor fixing bolt 31b, etc.) can be easily moved in the axial direction, fixing work of the heat exchange section 10 and the fan motor 20 can be facilitated.
　また、本実施形態では、複数の仮止部（左側仮止部１８やモータ仮止部３２）が、熱交換部１０及びファンモータ２０の重心を挟んで配置されている。これにより、仮止部（左側仮止部１８やモータ仮止部３２）に仮止めされる熱交換部１０及びファンモータ２０が安定する。したがって、熱交換部１０及びファンモータ２０の固定作業を容易化することができる。 Further, in this embodiment, a plurality of temporary fixing portions (the left temporary fixing portion 18 and the motor temporary fixing portion 32) are arranged with the center of gravity of the heat exchange portion 10 and the fan motor 20 interposed therebetween. As a result, the heat exchange portion 10 and the fan motor 20 temporarily fixed to the temporary fixing portions (the left temporary fixing portion 18 and the motor temporary fixing portion 32) are stabilized. Therefore, the fixation work of the heat exchange section 10 and the fan motor 20 can be facilitated.

　次に、仕切板５２を筐体２に固定する方法について説明する。
　まず、仕切板５２に固定された仕切板仮止ボルト５５ｂの段部を、第１直線部５９ａの下端から仮止用切欠き５９に導入する。次に、仕切板仮止ボルト５５ｂを仮止用切欠き５９に沿って移動させ、第３直線部５９ｃの下端まで移動させる（図１２参照）。このようにして、まず、仕切板５２を筐体２に対して仮止めする（保持工程）。なお、仮止めは、左右同時に行ってもよく、どちらか一方を先に行ってもよい。 Next, a method for fixing the partition plate 52 to the housing 2 will be described.
First, the step portion of the partition plate temporary fixing bolt 55b fixed to the partition plate 52 is introduced into the temporary fixing notch 59 from the lower end of the first linear portion 59a. Next, the partition plate temporary fixing bolt 55b is moved along the temporary fixing notch 59 to the lower end of the third linear portion 59c (see FIG. 12). In this way, first, the partition plate 52 is temporarily fixed to the housing 2 (holding step). Temporary fixing may be performed on the left and right at the same time, or one of them may be performed first.
　仕切板５２が仮止めされると、作業員が仕切板５２を支持していない状態となった場合であっても、仮止用切欠き５９の第３直線部５９ｃの下縁が、仕切板仮止ボルト５５ｂを下方から支持する。したがって、仕切板５２が筐体２に対して保持された状態（仮止めされた状態）が維持される。また、この状態では、仕切板５２の前後方向の移動は、第３直線部５９ｃの前縁及び後縁によって規制される。また、仕切板５２の上下方向の移動は、第３直線部５９ｃの長さの分だけ許容される。また、仕切板５２の幅方向の移動は、仕切板係止ボルトの頭部が突出する分だけ許容される。それ以上の幅方向の移動は、頭部と左側壁部５８または右側壁部５７とが干渉するため、規制される。 When the partition plate 52 is temporarily fixed, the lower edge of the third linear portion 59c of the temporary fixing notch 59 is aligned with the partition plate even if the operator does not support the partition plate 52. The temporary fixing bolt 55b is supported from below. Therefore, the state in which the partition plate 52 is held with respect to the housing 2 (the temporarily fixed state) is maintained. Further, in this state, movement of the partition plate 52 in the front-rear direction is restricted by the front and rear edges of the third linear portion 59c. Further, the vertical movement of the partition plate 52 is allowed by the length of the third linear portion 59c. Further, the movement of the partition plate 52 in the width direction is allowed only by the projection of the head portion of the partition plate locking bolt. Further movement in the width direction is restricted because the head interferes with the left side wall portion 58 or the right side wall portion 57 .
　左右両方の仮止めが完了すると、仕切板５２を筐体２側の部材（本実施形態では左側壁部５８、右側壁部５７及び天井部５）に固定する作業を行う。具体的には、仕切板５２の上側フランジ部５４を上方へ移動させ、各貫通孔を挿通するボルトによって、上側フランジ部５４を天井部５に固定する。また、仕切板５２の左側フランジ部５５を左方へ移動させ、各貫通孔を挿通するボルトによって、左側フランジ部５５を左側壁部５８に固定する。また、仕切板５２の右側フランジ部５６を右方へ移動させ、各貫通孔を挿通するボルトによって、右側フランジ部５６を右側壁部５７に固定する。
　以上のように、上側フランジ部５４、左側フランジ部５５及び右側フランジ部５６が筐体２に対して固定されることで、仕切板５２が筐体２に固定される（図１０参照）。なお、仕切板５２が筐体２に固定された状態では、仮止めが解除されている。 When both the left and right sides are temporarily fixed, the work of fixing the partition plate 52 to the members on the housing 2 side (in this embodiment, the left side wall portion 58, the right side wall portion 57, and the ceiling portion 5) is performed. Specifically, the upper flange portion 54 of the partition plate 52 is moved upward, and the upper flange portion 54 is fixed to the ceiling portion 5 with bolts inserted through the through holes. Also, the left flange portion 55 of the partition plate 52 is moved to the left, and the left flange portion 55 is fixed to the left wall portion 58 by bolts inserted through the respective through holes. Also, the right flange portion 56 of the partition plate 52 is moved to the right, and the right flange portion 56 is fixed to the right side wall portion 57 by bolts inserted through the respective through holes.
By fixing the upper flange portion 54, the left flange portion 55, and the right flange portion 56 to the housing 2 as described above, the partition plate 52 is fixed to the housing 2 (see FIG. 10). It should be noted that the temporary fixing is released when the partition plate 52 is fixed to the housing 2 .
