　弾性部６１は、第１弾性部６１ａと、第１弾性部６１ａの上側で第１弾性部６１ａに繋がる第２弾性部６１ｂと、を含む。第１弾性部６１ａは、第１蓋部５１から第１蓋部５１の板面５１ａと平行に延びる。一方で、第２弾性部６１ｂは、第１蓋部５１の板面５１ａに対し左側（－Ｙ側）に傾斜する。 The elastic part 61 includes a first elastic part 61a and a second elastic part 61b connected to the first elastic part 61a above the first elastic part 61a. The first elastic portion 61a extends from the first lid portion 51 in parallel to the plate surface 51a of the first lid portion 51. On the other hand, the second elastic portion 61b is inclined to the left (−Y side) with respect to the plate surface 51a of the first lid portion 51.

Further, FIG. 9 is a schematic cross-sectional view taken along line IX-IX in FIG. 8. Furthermore, FIG. 11 is a schematic cross-sectional view taken along the line XI-XI in FIG.
　図８、図９に示す制御装置２４と、図１０、図１１に示す制御装置２４とは、互いに異なる機種の室内機２０に搭載される。以下の説明において、図８、図９に示す制御装置２４を第１制御装置２４Ａと呼び、図１０、図１１に示す制御装置２４を第２制御装置２４Ｂと呼ぶ。第１制御装置２４Ａと第２制御装置２４Ｂとは、接続される配線３９の本数が異なる。第２制御装置２４Ｂに接続される配線３９の本数は、第１制御装置２４Ａに接続される配線３９の本数より多い。 The control device 24 shown in FIGS. 8 and 9 and the control device 24 shown in FIGS. 10 and 11 are installed in indoor units 20 of different models. In the following description, the control device 24 shown in FIGS. 8 and 9 will be referred to as a first control device 24A, and the control device 24 shown in FIGS. 10 and 11 will be referred to as a second control device 24B. The first control device 24A and the second control device 24B differ in the number of wires 39 connected to them. The number of wires 39 connected to the second control device 24B is greater than the number of wires 39 connected to the first control device 24A.
　なお、本実施の形態では、第１制御装置２４Ａ、および第２制御装置２４Ｂに接続される全ての配線３９の断面積はほぼ等しいものとして説明する。しかしながら、複数の配線３９は、断面積の異なる複数種類の配線を含んでいてもよい。 In this embodiment, the cross-sectional area of all the wirings 39 connected to the first control device 24A and the second control device 24B will be described as being approximately equal. However, the plurality of wirings 39 may include a plurality of types of wirings having different cross-sectional areas.
　図８に示すように、側壁部４１ｃは、電装品箱３０の収容空間Ａを下側から覆う。側壁部４１ｃの先端は、蓋体５０の板面５１ａに対向する。側壁部４１ｃの上側には、蓋体５０の第１リブ５３ａが重なる。側壁部４１ｃの上面と第１リブ５３ａの下面とは、互いに接触していてもよい。 As shown in FIG. 8, the side wall portion 41c covers the housing space A of the electrical component box 30 from below. The tip of the side wall portion 41c faces the plate surface 51a of the lid 50. The first rib 53a of the lid body 50 overlaps the upper side of the side wall portion 41c. The upper surface of the side wall portion 41c and the lower surface of the first rib 53a may be in contact with each other.
　本実施の形態の電装品箱３０は、ケース４０の側壁部４１ｃの上側に蓋体５０の第１リブ５３ａが重なることでケース４０に蓋体５０が組み付けられる。すなわち、蓋体５０は、ケース４０にインロー構造によって組み付けられる。このため、ケース４０と蓋体との間の隙間を狭くすることができ、電装品箱３０内への小動物の侵入を抑制できる。 In the electrical component box 30 of this embodiment, the lid 50 is assembled to the case 40 by overlapping the first rib 53a of the lid 50 with the upper side of the side wall 41c of the case 40. That is, the lid body 50 is assembled to the case 40 by a spigot structure. Therefore, the gap between the case 40 and the lid can be narrowed, and small animals can be prevented from entering the electrical component box 30.
　図９に示すように、側壁部４１ｃの切欠部４５は、蓋体５０側（すなわち右側）に開口する。切欠部４５の内縁４５ａの一部は、第１リブ５３ａの先端部より、底板部４１ａ側（すなわち左側）に配置される。また、第１リブ５３ａの蓋側切欠部５４は、切欠部４５の直上に配置される。 As shown in FIG. 9, the notch 45 of the side wall 41c opens on the lid 50 side (ie, on the right side). A part of the inner edge 45a of the notch 45 is located closer to the bottom plate 41a (ie, to the left) than the tip of the first rib 53a. Further, the lid side notch 54 of the first rib 53a is arranged directly above the notch 45.
　側壁部４１ｃの板厚方向（本実施の形態では鉛直方向Ｚ）から見て、切欠部４５の内縁４５ａと蓋側切欠部５４の内縁５４ａとは、略矩形状の開口を形成する。切欠部４５の内縁４５ａと蓋側切欠部５４の内縁５４ａは、電装品箱３０の収容空間Ａを外部空間に連通させる配線出入口３０ａを構成する。 When viewed from the thickness direction of the side wall portion 41c (vertical direction Z in this embodiment), the inner edge 45a of the notch 45 and the inner edge 54a of the lid-side notch 54 form a substantially rectangular opening. The inner edge 45a of the notch 45 and the inner edge 54a of the lid-side notch 54 constitute a wiring entrance/exit 30a that communicates the storage space A of the electrical component box 30 with the external space.
　複数の配線３９は、切欠部４５の内部に配置される。複数の配線３９は、板バネ部６０の接触部６２に接触する。板バネ部６０は、複数の配線３９を切欠部４５の内縁４５ａに押し当てる。これにより、板バネ部６０は、配線３９が切欠部４５から離脱することを抑制する。さらに、板バネ部６０は、配線３９同士を接触させて配線３９の間の隙間を最小にする。これにより、板バネ部６０は、配線出入口３０ａを介する小動物、および埃の電装品箱３０内への侵入を抑制する。 The plurality of wirings 39 are arranged inside the notch 45. The plurality of wires 39 contact the contact portion 62 of the leaf spring portion 60 . The leaf spring section 60 presses the plurality of wires 39 against the inner edge 45a of the cutout section 45. Thereby, the leaf spring section 60 suppresses the wiring 39 from separating from the notch section 45 . Further, the leaf spring portion 60 brings the wirings 39 into contact with each other to minimize the gap between the wirings 39. As a result, the leaf spring portion 60 prevents small animals and dust from entering the electrical component box 30 through the wiring entrance/exit 30a.
　図８に示すように、板バネ部６０は、接触部６２において複数の配線３９に接触する。また、板バネ部６０は、複数の配線３９を切欠部４５の内縁４５ａ側に押し当てるとともに、配線３９から受ける反力によって蓋体５０側（すなわち右側）に撓む。 As shown in FIG. 8, the leaf spring section 60 contacts the plurality of wirings 39 at the contact section 62. Further, the leaf spring portion 60 presses the plurality of wires 39 against the inner edge 45a side of the notch portion 45, and is bent toward the lid 50 (ie, to the right) by the reaction force received from the wires 39.
　図８、および図９に示す第１制御装置２４Ａでは、配線出入口３０ａを通過する配線３９の本数が比較的少ない。したがって、第１制御装置２４Ａにおける、板バネ部６０のたわみ量は、比較的小さい。
　一方で、図１０、および図１１に示す第２制御装置２４Ｂでは、配線出入口３０ａを通過する配線３９の本数が、第１制御装置２４Ａと比較して多い。したがって、第２制御装置２４Ｂにおける、板バネ部６０のたわみ量は、第１制御装置２４Ａと比較して大きくなる。 In the first control device 24A shown in FIGS. 8 and 9, the number of wires 39 passing through the wire entrance/exit 30a is relatively small. Therefore, the amount of deflection of the leaf spring section 60 in the first control device 24A is relatively small.
On the other hand, in the second control device 24B shown in FIGS. 10 and 11, the number of wires 39 passing through the wire entrance/exit 30a is larger than in the first control device 24A. Therefore, the amount of deflection of the leaf spring portion 60 in the second control device 24B is larger than that in the first control device 24A.
　本実施の形態において、切欠部４５の開口面積、および板バネ部６０の配置などは、想定される配線３９の本数が最も少ない場合であっても、配線３９と板バネ部６０の接触が確保されるように設定される。したがって、板バネ部６０は、如何なる機種の制御装置２４においても、弾性部６１において弾性変形する。これにより、板バネ部６０が、複数の配線３９を切欠部４５の内縁４５ａに押し当てて、配線出入口３０ａに大きな隙間が生じることを抑制する。 In this embodiment, the opening area of the notch 45 and the arrangement of the leaf spring part 60 ensure contact between the wiring 39 and the leaf spring part 60 even when the expected number of wirings 39 is the smallest. is set so that Therefore, the leaf spring section 60 is elastically deformed in the elastic section 61 in any model of the control device 24. Thereby, the leaf spring portion 60 presses the plurality of wires 39 against the inner edge 45a of the notch portion 45, thereby suppressing the formation of a large gap at the wire entrance/exit 30a.
　図８に示すように、本実施の形態の接触部６２は、側壁部４１ｃの下側に配置される。このため、配線３９と板バネ部６０との接触位置を、配線３９と切欠部４５内縁４５ａとの接触位置に対し、下側にずらして配置できる。これにより、配線３９の一部位に左右両側から力が集中して付与されることを抑制できる。 As shown in FIG. 8, the contact portion 62 of this embodiment is arranged below the side wall portion 41c. Therefore, the contact position between the wiring 39 and the leaf spring portion 60 can be shifted downward with respect to the contact position between the wiring 39 and the inner edge 45a of the notch 45. Thereby, it is possible to prevent force from being concentrated and applied to one portion of the wiring 39 from both the left and right sides.
　図８に示すように、本実施の形態の閉塞板部６３は、側壁部４１ｃの下側に配置される。また、図９に示すように、閉塞板部６３は、側壁部４１ｃの板厚方向から見て切欠部４５と重なる。閉塞板部６３は、配線出入口３０ａのうち、配線３９が通過しない領域を閉塞する。 As shown in FIG. 8, the closing plate portion 63 of this embodiment is arranged below the side wall portion 41c. Further, as shown in FIG. 9, the closing plate portion 63 overlaps the notch portion 45 when viewed from the thickness direction of the side wall portion 41c. The closing plate portion 63 closes off a region of the wiring entrance/exit 30a through which the wiring 39 does not pass.
　本実施の形態において、閉塞板部６３の幅寸法Ｄ１は、切欠部４５の開口幅Ｄ２よりも大きい。このため、閉塞板部６３は、幅方向両側で側壁部４１ｃに重なる。本実施の形態によれば、閉塞板部６３が、側壁部４１ｃの板厚方向一方側（下側）で側壁部４１ｃに重なるように配置される。これにより、閉塞板部６３を切欠部４５の内部に配置する場合と比較して、閉塞板部６３と側壁部４１ｃとの間の隙間を小さくすることができ、電装品箱３０の収容空間Ａへの小動物の侵入を抑制できる。 In this embodiment, the width dimension D1 of the closing plate portion 63 is larger than the opening width D2 of the notch portion 45. Therefore, the closing plate portion 63 overlaps the side wall portion 41c on both sides in the width direction. According to this embodiment, the closing plate portion 63 is arranged so as to overlap the side wall portion 41c on one side (lower side) in the thickness direction of the side wall portion 41c. Thereby, compared to the case where the closing plate part 63 is arranged inside the notch part 45, the gap between the closing plate part 63 and the side wall part 41c can be made smaller, and the housing space A of the electrical component box 30 can be made smaller. It can prevent small animals from entering.
　図１０に示すように、第１リブ５３ａの蓋側切欠部５４は、側壁部４１ｃの板厚方向から見て切欠部４５に重なる。蓋側切欠部５４は、切欠部４５を通過する配線３９の本数が多い場合に、切欠部４５の上側で配線３９が第１リブ５３ａに干渉することを抑制する。このため、第１リブ５３ａとの干渉によって配線３９が急激に折り曲げられるなど、配線３９に大きな負荷が加わることを抑制できる。 As shown in FIG. 10, the lid-side notch 54 of the first rib 53a overlaps the notch 45 when viewed from the thickness direction of the side wall 41c. The lid side notch 54 prevents the wiring 39 from interfering with the first rib 53a above the notch 45 when the number of wirings 39 passing through the notch 45 is large. Therefore, it is possible to prevent a large load from being applied to the wiring 39, such as the wiring 39 being suddenly bent due to interference with the first rib 53a.
　図３に示すように、本実施の形態の室内機２０は、熱交換器２２と、送風機２３と、制御装置２４と、熱交換器２２、送風機２３、および制御装置２４を内部に収容する筐体２１と、を備える。図８に示すように、制御装置２４は、複数の配線３９が接続される第１回路基板３１、および第１回路基板３１を収容する電装品箱３０を有する。また、本実施の形態の電装品箱３０は、第１回路基板３１を囲む側壁部４１ｃと、第１回路基板３１を覆う蓋体５０と、蓋体５０に設けられる板バネ部６０と、を有する。側壁部４１ｃには、複数の配線３９を通す切欠部４５が設けられる。板バネ部６０は、切欠部４５の内縁４５ａに複数の配線３９を押し当てる。 As shown in FIG. 3, the indoor unit 20 of the present embodiment includes a heat exchanger 22, a blower 23, a control device 24, and a casing that houses the heat exchanger 22, the blower 23, and the control device 24 inside. A body 21 is provided. As shown in FIG. 8, the control device 24 includes a first circuit board 31 to which a plurality of wires 39 are connected, and an electrical component box 30 that accommodates the first circuit board 31. Further, the electrical component box 30 of the present embodiment includes a side wall portion 41c surrounding the first circuit board 31, a lid body 50 that covers the first circuit board 31, and a leaf spring portion 60 provided on the lid body 50. have The side wall portion 41c is provided with a cutout portion 45 through which the plurality of wiring lines 39 are passed. The leaf spring section 60 presses the plurality of wires 39 against the inner edge 45a of the cutout section 45.
　本実施の形態によれば、板バネ部６０によって複数の配線３９を切欠部４５の内縁４５ａに押し付ける。これにより、切欠部４５の内縁４５ａと複数の配線３９との間、複数の配線３９同士の間、並びに配線３９と板バネ部６０との間に、大きな隙間が生じることを抑制できる。結果的に、配線出入口３０ａから虫などの小動物、および埃が、電装品箱３０の収容空間Ａに侵入することを抑制できる。 According to this embodiment, the plurality of wirings 39 are pressed against the inner edge 45a of the notch 45 by the leaf spring section 60. This can suppress the generation of large gaps between the inner edge 45a of the notch 45 and the plurality of wires 39, between the plurality of wires 39, and between the wires 39 and the leaf spring portion 60. As a result, small animals such as insects and dust can be prevented from entering the housing space A of the electrical component box 30 through the wiring entrance 30a.
　本実施の形態の電装品箱３０によれば、配線出入口３０ａの開口部面積（複数の配線３９の通過を許容する面積、同じ）の大きさが、板バネ部６０の弾性変形によって調整される。図８および図１０に示すように、機種ごとに切欠部４５を通過する配線３９の本数が変わる場合でも、板バネ部６０の弾性変形量が自動的に変わり開口部面積が適切に調整される。本実施の形態によれば、機種ごとに開口部面積を調整する部材を別途用意する必要がなく、複数の機種の室内機２０に対し部品数の低減を図ることができる。 According to the electrical component box 30 of the present embodiment, the size of the opening area of the wiring entrance 30a (the same area that allows the passage of a plurality of wirings 39) is adjusted by elastic deformation of the leaf spring portion 60. . As shown in FIGS. 8 and 10, even if the number of wires 39 passing through the notch 45 changes depending on the model, the amount of elastic deformation of the leaf spring section 60 automatically changes and the opening area is adjusted appropriately. . According to the present embodiment, there is no need to separately prepare a member for adjusting the opening area for each model, and it is possible to reduce the number of parts for the indoor units 20 of a plurality of models.
　本実施の形態によれば、図９に示すように、板バネ部６０によって複数の配線３９を切欠部４５の内縁４５ａに押し付けることで、切欠部４５内で複数の配線３９を位置決めすることができる。本実施の形態によれば、振動などで配線３９が移動することを抑制でき、配線３９の間、または切欠部４５の内縁４５ａとの間に、大きな隙間が生じることを抑制できる。 According to this embodiment, as shown in FIG. 9, the plurality of wirings 39 can be positioned within the notch 45 by pressing the plurality of wirings 39 against the inner edge 45a of the notch 45 by the leaf spring section 60. can. According to the present embodiment, it is possible to suppress the wiring 39 from moving due to vibrations, etc., and it is possible to suppress the generation of large gaps between the wiring 39 or between the wiring 39 and the inner edge 45a of the notch 45.
　特に、本実施の形態の制御装置２４には、複数の配線３９が設けられる。配線が単数である場合、バネ状の部材で配線を単純に挟むことで配線を位置決めできる。しかしながら、配線３９が複数設けられる場合、複数の配線を単純に並べてバネ状の部材で挟むのみであれば、配線３９の個体差、種類の違いの起因する太さの差によって一部の配線３９の支持が不十分になって挟み込んだ部分から一部の配線が離脱する虞がある。本実施の形態によれば、複数の配線３９を、切欠部４５に配置し板バネ部６０によって内縁４５ａに押し付けることで、複数の配線３９の位置決めをより確実に行うことができる。 In particular, the control device 24 of this embodiment is provided with a plurality of wiring lines 39. When there is a single wire, the wire can be positioned by simply sandwiching the wire between spring-like members. However, when a plurality of wires 39 are provided, if the plurality of wires are simply arranged and sandwiched between spring-like members, some of the wires 39 may be There is a risk that some of the wiring may become detached from the sandwiched part due to insufficient support. According to this embodiment, by arranging the plurality of wirings 39 in the notch portion 45 and pressing the plurality of wirings 39 against the inner edge 45a by the leaf spring portion 60, the plurality of wirings 39 can be positioned more reliably.
　また、本実施の形態によれば、側壁部４１ｃに蓋体５０を組み付けることで、自動的に板バネ部６０が配線３９を切欠部４５の内縁４５ａに押し付けるため、複数の配線３９を容易に位置決めできる。特に本実施の形態では、側壁部４１ｃがケース４０の一部であるため、ケース４０の開口に蓋体５０を組み付けることで、配線３９の位置決めを容易に行うことができる。 Further, according to the present embodiment, by assembling the lid 50 to the side wall portion 41c, the leaf spring portion 60 automatically presses the wires 39 against the inner edge 45a of the cutout portion 45, so that the plurality of wires 39 can be easily connected. Can be positioned. Particularly in this embodiment, since the side wall portion 41c is a part of the case 40, the wiring 39 can be easily positioned by assembling the lid 50 into the opening of the case 40.

The elastic portion 61 is fixed to the lid 50 and elastically deforms. The contact portion 62 is located at the tip of the elastic portion 61 and contacts the plurality of wirings 39 . The closing plate portion 63 extends from the contact portion 62 along the wall surface of the side wall portion 41c.
　本実施の形態によれば、閉塞板部６３は、切欠部４５の開口の少なくとも一部を閉塞する。このため、接触部６２において配線３９を切欠部４５の内縁４５ａ側に押し付けるとともに、切欠部４５の開口内であって配線３９が配置されない領域を容易に閉塞できる。これにより、配線出入口３０ａに大きな隙間が生じることを抑制できる。なお、ここで切欠部４５の開口とは、切欠部４５の内縁４５ａによって囲まれる領域を意味する。 According to this embodiment, the closing plate portion 63 closes at least a portion of the opening of the notch portion 45. Therefore, the wiring 39 is pressed against the inner edge 45a of the notch 45 at the contact portion 62, and the area within the opening of the notch 45 where the wiring 39 is not placed can be easily closed. Thereby, it is possible to suppress the formation of a large gap in the wiring entrance/exit 30a. Note that the opening of the notch 45 here means a region surrounded by the inner edge 45a of the notch 45.
　本実施の形態によれば、板バネ部６０の接触部６２が、側壁部４１ｃの板厚方向の一方側（本実施の形態では下側）に配置される。このため、配線３９を挟む側壁部４１ｃの内縁４５ａと接触部６２とを側壁部４１ｃの板厚方向においてずらして配置でき、配線３９の一箇所に応力が集中して付与されることを抑制できる。 According to this embodiment, the contact portion 62 of the leaf spring portion 60 is arranged on one side (lower side in this embodiment) of the side wall portion 41c in the thickness direction. Therefore, the inner edge 45a of the side wall portion 41c sandwiching the wiring 39 and the contact portion 62 can be arranged to be shifted in the thickness direction of the side wall portion 41c, and it is possible to suppress stress from being concentrated at one location on the wiring 39. .
　本実施の形態によれば、板バネ部６０の閉塞板部６３が、側壁部４１ｃの板厚方向の一方側（本実施の形態では下側）に配置される。さらに本実施の形態によれば、閉塞板部６３の幅寸法Ｄ１が、切欠部４５の開口幅Ｄ２よりも大きく幅方向両側で側壁部４１ｃに重なる。このため、板バネ部６０の幅方向両端部と切欠部４５の内縁４５ａとの間に、小動物および埃の侵入経路となる隙間が生じることを抑制できる。 According to this embodiment, the closing plate portion 63 of the leaf spring portion 60 is arranged on one side (lower side in this embodiment) of the side wall portion 41c in the thickness direction. Further, according to the present embodiment, the width dimension D1 of the closing plate portion 63 is larger than the opening width D2 of the notch portion 45 and overlaps with the side wall portion 41c on both sides in the width direction. Therefore, it is possible to suppress the formation of a gap that becomes an intrusion path for small animals and dust between both ends in the width direction of the leaf spring portion 60 and the inner edge 45a of the notch portion 45.
　本実施の形態において、蓋体５０には、側壁部４１ｃに沿って延びる第１リブ５３ａが設けられる。第１リブ５３ａには、側壁部４１ｃの板厚方向から見て切欠部４５と少なくとも一部が重なる蓋側切欠部５４が設けられる。 In this embodiment, the lid 50 is provided with a first rib 53a extending along the side wall 41c. The first rib 53a is provided with a lid-side notch 54 that at least partially overlaps the notch 45 when viewed from the thickness direction of the side wall 41c.
　本実施の形態において、蓋体５０に第１リブ５３ａが設けられるため、第１リブ５３ａと側壁部４１ｃとによって蓋体５０とケース４０とのインロー構造を実現できる。これにより、蓋体５０とケース４０との間に大きな隙間が生じることを抑制できる。 In this embodiment, since the first rib 53a is provided on the lid 50, a spigot structure between the lid 50 and the case 40 can be realized by the first rib 53a and the side wall portion 41c. Thereby, it is possible to suppress the generation of a large gap between the lid body 50 and the case 40.
　本実施の形態によれば、蓋側切欠部５４によって、電装品箱３０の収容空間Ａに導かれる配線３９と第１リブ５３ａとの干渉が抑制され、配線３９に負荷が加わることを抑制できる。 According to the present embodiment, the lid-side notch 54 suppresses interference between the wiring 39 led to the housing space A of the electrical component box 30 and the first rib 53a, thereby suppressing the load on the wiring 39. .
　本実施の形態において、蓋体５０は、第１蓋部５１と第２蓋部５２とを有する。第１蓋部５１は、板バネ部６０と一体的に成形される。第１蓋部５１には、第１蓋部５１の板厚方向から見て板バネ部６０と重なる孔部５１ｈが設けられる。第２蓋部５２は、第１蓋部５１の外側の面を覆う。第２蓋部５２は、孔部５１ｈを閉塞する。 In this embodiment, the lid body 50 has a first lid part 51 and a second lid part 52. The first lid portion 51 is integrally molded with the leaf spring portion 60. The first lid part 51 is provided with a hole 51h that overlaps the leaf spring part 60 when viewed from the thickness direction of the first lid part 51. The second lid part 52 covers the outer surface of the first lid part 51. The second lid portion 52 closes the hole portion 51h.
　本実施の形態によれば、第１蓋部５１に板厚方向から見て重なる孔部５１ｈを設けることで、第１蓋部５１を樹脂成形によって製造する場合に、第１蓋部５１の板厚方向を金型の割方向として、第１蓋部５１、および板バネ部６０を容易に成形できる。また、第１蓋部５１をプレス加工によって製造する場合においても、第１蓋部５１の板厚方向をプレス方向として、第１蓋部５１、および板バネ部６０を容易に成形できる。 According to this embodiment, by providing the first lid part 51 with the overlapping holes 51h when viewed from the plate thickness direction, when the first lid part 51 is manufactured by resin molding, the plate of the first lid part 51 can be The first lid portion 51 and the leaf spring portion 60 can be easily molded by setting the thickness direction as the cutting direction of the mold. Further, even when manufacturing the first lid part 51 by press working, the first lid part 51 and the leaf spring part 60 can be easily molded with the plate thickness direction of the first lid part 51 set as the pressing direction.
　本実施の形態によれば、孔部５１ｈが第２蓋部５２によって閉塞されるため、孔部５１ｈを介して電装品箱３０の収容空間Ａ側に小動物、および埃が侵入することを抑制できる。また、第２蓋部５２が孔部５１ｈを閉塞することで、図８に示すように、板バネ部６０の変形方向には、第２蓋部５２が配置される。このため、板バネ部６０の弾性変形量は、閉塞板部６３と第２蓋部５２との間の隙間寸法以内に制限される。本実施の形態によれば、板バネ部６０が、弾性領域を超えて塑性変形することを抑制することができる。したがって、組立時に切欠部４５内の配線３９が未整列であることによって、板バネ部６０過剰な力が加わる場合などに、板バネ部６０に損傷が生じることを抑制できる。 According to this embodiment, since the hole 51h is closed by the second lid 52, it is possible to suppress small animals and dust from entering the housing space A side of the electrical component box 30 through the hole 51h. . In addition, as the second lid portion 52 closes the hole 51h, the second lid portion 52 is arranged in the deformation direction of the leaf spring portion 60, as shown in FIG. Therefore, the amount of elastic deformation of the leaf spring section 60 is limited to within the gap size between the closing plate section 63 and the second lid section 52. According to the present embodiment, it is possible to suppress plastic deformation of the leaf spring portion 60 beyond the elastic region. Therefore, damage to the leaf spring part 60 can be suppressed when an excessive force is applied to the leaf spring part 60 due to the wiring 39 in the notch 45 being unaligned during assembly.
　本実施の形態において、板バネ部６０は、第１蓋部５１から第１蓋部５１の板面５１ａと平行に延びる第１弾性部６１ａと、第１弾性部６１ａに繋がり板面５１ａに対し複数の配線３９側に傾斜する第２弾性部６１ｂと、を有する。 In the present embodiment, the leaf spring section 60 includes a first elastic section 61a extending from the first lid section 51 in parallel to the plate surface 51a of the first lid section 51, and a first elastic section 61a connected to the first elastic section 61a with respect to the plate surface 51a. The second elastic portion 61b is inclined toward the plurality of wiring lines 39.
　弾性部６１は、複数の配線３９から接触部６２に対し力が付与されると、複数の配線３９側に傾斜する第２弾性部６１ｂが、第１弾性部６１ａよりも優先的に変形する。したがって、第１弾性部６１ａは、弾性部６１において、比較的変形量が小さくなる。本実施の形態によれば、弾性部６１の根元であって第１蓋部５１との接続部分に、比較的変形量小さい第１弾性部６１ａが配置される。このため、第１蓋部５１の孔部５１ｈの内縁と弾性部６１との境界部分に発生する応力集中を小さくすることができ、弾性部６１が大きく変形しても根元部分に損傷を生じることを抑制できる。 In the elastic portion 61, when a force is applied to the contact portion 62 from the plurality of wires 39, the second elastic portion 61b that is inclined toward the plurality of wires 39 deforms preferentially than the first elastic portion 61a. Therefore, in the first elastic portion 61a, the amount of deformation in the elastic portion 61 is relatively small. According to the present embodiment, the first elastic portion 61a with a relatively small amount of deformation is arranged at the base of the elastic portion 61 and at the connection portion with the first lid portion 51. Therefore, stress concentration occurring at the boundary between the inner edge of the hole 51h of the first lid part 51 and the elastic part 61 can be reduced, and even if the elastic part 61 is significantly deformed, damage to the root part will not occur. can be suppressed.
