（２）詳細
以下、本実施形態の車載デバイス１について図１〜図５を用いて詳細に説明する。本実施形態の車載デバイス１は、第１接続端子１１と、第２接続端子１２と、ケース２と、電池３と、基板４と、音響装置５と、を備えている。 (2) Details Hereinafter, the in-vehicle device 1 of the present embodiment will be described in detail with reference to FIGS. 1 to 5. The vehicle-mounted device 1 of the present embodiment includes a first connection terminal 11, a second connection terminal 12, a case 2, a battery 3, a substrate 4, and an audio device 5.

第１接続端子１１は、例えばＳＵＳ等の金属材料により形成されており、図４Ａに示すように、第１主片１１１と、第１接触片１１２と、第１繋ぎ片１１３と、を有している。第１主片１１１は、上下方向に長い矩形状であり、後述する電池収容部２３の第１差込部２３４に差し込み可能に形成されている。第１主片１１１は、その中央部に矩形状の開口１１４を有している。第１主片１１１には、抑えばね１３が一体に形成されている。本開示でいう「一体に形成」とは、２以上の部材の材料が同じ材料であり、これらの部材が一体に成型、または一体に加工されていることをいう。以下、「一体である」も同じ意味である。 The first connection terminal 11 is made of a metal material such as SUS, and has, as shown in FIG. 4A, a first main piece 111, a first contact piece 112, and a first connecting piece 113. ing. The first main piece 111 has a rectangular shape that is long in the vertical direction, and is formed so as to be insertable into the first insertion portion 234 of the battery accommodating portion 23, which will be described later. The first main piece 111 has a rectangular opening 114 at the center thereof. A holding spring 13 is integrally formed on the first main piece 111. The term "integrally formed" as used in the present disclosure means that the materials of two or more members are the same material, and these members are integrally molded or integrally processed. Hereinafter, "one" has the same meaning.

抑えばね１３は、上下方向に長い矩形状であり、第１主片１１１の開口１１４の下端縁から上向きに突出している。抑えばね１３は、開口１１４の下端縁を支点として折り曲げられており、第１主片１１１の厚さ方向に撓み可能に構成されている。抑えばね１３は、電池収容部２３に電池３が挿入される際に、後述する絶縁部材２３３を間に挟んで電池３に間接的に押されることにより、電池３から離れる向きに撓むように構成されている。 The holding spring 13 has a rectangular shape that is long in the vertical direction, and projects upward from the lower end edge of the opening 114 of the first main piece 111. The holding spring 13 is bent around the lower end edge of the opening 114 as a fulcrum, and is configured to be flexible in the thickness direction of the first main piece 111. When the battery 3 is inserted into the battery accommodating portion 23, the holding spring 13 is configured to bend in a direction away from the battery 3 by being indirectly pushed by the battery 3 with an insulating member 233, which will be described later, sandwiched between the holding spring 13. ing.

抑えばね１３の上端は、絶縁部材２３３に引っ掛かることがないように、開口１１４に向かう向きに折り曲げられている。言い換えれば、抑えばね１３の電池３の第２面３２と接触する側の一端は、電池収容部２３に電池３が収容された状態において、電池３の第２面３２から離れる向きに折り曲げられている。 The upper end of the holding spring 13 is bent in the direction toward the opening 114 so as not to be caught by the insulating member 233. In other words, one end of the holding spring 13 on the side in contact with the second surface 32 of the battery 3 is bent in a direction away from the second surface 32 of the battery 3 in a state where the battery 3 is housed in the battery accommodating portion 23. There is.

第１接触片１１２は、第１主片１１１の短手方向に長い矩形状に形成されている。第１接触片１１２は、電池収容部２３に電池３を収容した状態で、電池３の負極３３に弾性的に接触するように構成されている。第１繋ぎ片１１３は、上下方向に長い矩形状の板の中間部を折り曲げた形状であり、第１主片１１１と第１接触片１１２とを繋ぐ。 The first contact piece 112 is formed in a rectangular shape that is long in the lateral direction of the first main piece 111. The first contact piece 112 is configured to elastically contact the negative electrode 33 of the battery 3 with the battery 3 housed in the battery housing portion 23. The first connecting piece 113 has a shape in which an intermediate portion of a rectangular plate long in the vertical direction is bent, and connects the first main piece 111 and the first contact piece 112.

第１主片１１１は、一対の第１保持片１１５と、第１接続片１１６と、を有している。一対の第１保持片１１５は、それぞれ上下方向に長い矩形状であり、第１主片１１１の短手方向の両端縁の一部を切り起こして形成されている。一対の第１保持片１１５は、第１主片１１１を後述する第１差込部２３４に差し込む際に、それぞれ第１差込部２３４の一対の第１立壁２３４Ｂに押されて撓むように構成されている。このため、一対の第１保持片１１５は、第１主片１１１が第１差込部２３４に差し込まれた状態にて、第１差込部２３４を押す向きの弾性力を発生することにより、第１接続端子１１を第１差込部２３４に保持する。 The first main piece 111 has a pair of first holding pieces 115 and a first connecting piece 116. Each of the pair of first holding pieces 115 has a rectangular shape that is long in the vertical direction, and is formed by cutting out a part of both end edges of the first main piece 111 in the lateral direction. The pair of first holding pieces 115 are configured to be pushed and bent by the pair of first standing walls 234B of the first insertion portion 234 when the first main piece 111 is inserted into the first insertion portion 234 described later. ing. Therefore, the pair of first holding pieces 115 generate an elastic force in the direction of pushing the first insertion portion 234 in a state where the first main piece 111 is inserted into the first insertion portion 234. The first connection terminal 11 is held in the first insertion portion 234.

第１接続片１１６は、上下方向に長い棒状であり、第１主片１１１の上端であって、かつ第１主片１１１の短手方向の一端に一体に形成されている。第１接続片１１６は、スルーホール実装により基板４の回路４１に電気的に接続されている。このため、電池収容部２３に電池３が収容された状態にて、第１接触片１１２と電池３の負極３３とが電気的に接続されることにより、第１接続片１１６を介して電池３の負極３３と基板４の回路４１とが電気的に接続される。 The first connecting piece 116 has a long rod shape in the vertical direction, is formed at the upper end of the first main piece 111, and is integrally formed at one end of the first main piece 111 in the lateral direction. The first connection piece 116 is electrically connected to the circuit 41 of the substrate 4 by mounting through holes. Therefore, in a state where the battery 3 is housed in the battery housing portion 23, the first contact piece 112 and the negative electrode 33 of the battery 3 are electrically connected to each other, so that the battery 3 is connected via the first connection piece 116. The negative electrode 33 of the above and the circuit 41 of the substrate 4 are electrically connected.

第２接続端子１２は、例えばＳＵＳ等の金属材料により形成されており、図４Ｂに示すように、第２主片１２１と、第２接触片１２２と、第２繋ぎ片１２３と、を有している。第２主片１２１は、上下方向に長い矩形状であり、後述する電池収容部２３の第２差込口２３５に差し込み可能に形成されている。 The second connection terminal 12 is made of a metal material such as SUS, and has a second main piece 121, a second contact piece 122, and a second connecting piece 123, as shown in FIG. 4B. ing. The second main piece 121 has a rectangular shape that is long in the vertical direction, and is formed so that it can be inserted into the second insertion port 235 of the battery accommodating portion 23, which will be described later.

第２接触片１２２は、正方形状に形成されており、その中央部に上向きに突出する突部１２２Ａを有している。第２接触片１２２は、電池収容部２３に電池３を収容した状態で、突部１２２Ａを介して電池３の正極３４に弾性的に接触するように構成されている。第２繋ぎ片１２３は、上下方向に長い矩形状の板の中間部を折り曲げた形状であり、第２主片１２１と第２接触片１２２とを繋ぐ。 The second contact piece 122 is formed in a square shape, and has a protrusion 122A protruding upward at the center thereof. The second contact piece 122 is configured to elastically contact the positive electrode 34 of the battery 3 via the protrusion 122A in a state where the battery 3 is housed in the battery housing portion 23. The second connecting piece 123 has a shape in which an intermediate portion of a rectangular plate long in the vertical direction is bent, and connects the second main piece 121 and the second contact piece 122.

第２主片１２１は、一対の第２保持片１２４と、第２接続片１２５と、を有している。一対の第２保持片１２４は、それぞれ上下方向に長い矩形状であり、第２主片１２１の短手方向の両端縁の一部を切り起こして形成されている。一対の第２保持片１２４は、第２主片１２１を後述する第２差込部２３５に差し込む際に、それぞれ第２差込部２３５の一対の第２立壁２３５Ｂに押されて撓むように構成されている。このため、一対の第２保持片１２４は、第２主片１２１が第２差込部２３５に差し込まれた状態にて、第２差込部２３５を押す向きの弾性力を発生することにより、第２接続端子１２を第２差込部２３５に保持する。 The second main piece 121 has a pair of second holding pieces 124 and a second connecting piece 125. Each of the pair of second holding pieces 124 has a rectangular shape that is long in the vertical direction, and is formed by cutting out a part of both end edges of the second main piece 121 in the lateral direction. The pair of second holding pieces 124 are configured to be pushed and bent by the pair of second standing walls 235B of the second insertion portion 235 when the second main piece 121 is inserted into the second insertion portion 235 described later. ing.

（３）電池の取付方法
以下、本実施形態の車載デバイス１に電池３を取り付ける方法について図６Ａ及び図６Ｂを用いて説明する。車載デバイス１に電池３を取り付けていない状態では、図６Ａに示すように、絶縁部材２３３の一部（ここでは、上端部）は、電池収容部２３に電池３が挿入されている状態における第２面３２（同図の二点鎖線Ａ１）を超えた位置にある。この状態では、絶縁部材２３３は、撓んでいない。つまり、絶縁部材２３３は、電池３を電池収容部２３に挿入すると撓むように設計されている。このため、接続端子（第１接続端子）１１の抑えばね１３には、電池３を電池収容部２３に挿入していない状態において、絶縁部材２３３の変形による応力が加わらないので、抑えばね１３が電池３を抑えるための弾性力を失いにくい、という利点がある。 (3) Battery Mounting Method Hereinafter, a method of mounting the battery 3 in the vehicle-mounted device 1 of the present embodiment will be described with reference to FIGS. 6A and 6B. In the state where the battery 3 is not attached to the in-vehicle device 1, as shown in FIG. 6A, a part of the insulating member 233 (here, the upper end portion) is in a state where the battery 3 is inserted in the battery accommodating portion 23. It is located beyond the two-sided 32 (two-dot chain line A1 in the figure). In this state, the insulating member 233 is not bent. That is, the insulating member 233 is designed to bend when the battery 3 is inserted into the battery accommodating portion 23. Therefore, stress due to deformation of the insulating member 233 is not applied to the holding spring 13 of the connection terminal (first connection terminal) 11 when the battery 3 is not inserted into the battery accommodating portion 23, so that the holding spring 13 is used. There is an advantage that the elastic force for suppressing the battery 3 is not easily lost.

電池３を電池収容部２３に挿入すると、図６Ｂに示すように、絶縁部材２３３の傾斜面２３３Ａが電池３に押されることにより、絶縁部材２３３は、対向する周壁２３２に近付く向き（同図における左向き）に撓む。そして、絶縁部材２３３が撓むことにより、接続端子（第１接続端子）１１の抑えばね１３も、絶縁部材２３３に押されて、対向する周壁２３２に近付く向き（同図における左向き）に撓む。つまり、電池収容部２３に電池３が挿入されると、絶縁部材２３３及び抑えばね１３の両方が撓む。そして、絶縁部材２３３及び抑えばね１３が撓んだ状態で、電池収容部２３に電池３が収容される。 When the battery 3 is inserted into the battery accommodating portion 23, as shown in FIG. 6B, the inclined surface 233A of the insulating member 233 is pushed by the battery 3, so that the insulating member 233 approaches the facing peripheral wall 232 (in the figure). Bends to the left). Then, as the insulating member 233 bends, the holding spring 13 of the connecting terminal (first connecting terminal) 11 is also pushed by the insulating member 233 and bends in a direction approaching the facing peripheral wall 232 (to the left in the figure). .. That is, when the battery 3 is inserted into the battery accommodating portion 23, both the insulating member 233 and the holding spring 13 bend. Then, the battery 3 is accommodated in the battery accommodating portion 23 in a state where the insulating member 233 and the holding spring 13 are bent.

電池収容部２３に電池３が収容された状態では、絶縁部材２３３が元の状態（図６Ａに示す状態）に復帰しようとすることにより、絶縁部材２３３の弾性力が電池３の第２面３２に加わる。言い換えれば、絶縁部材２３３は、電池収容部２３に電池３が収容された状態で、電池３の第２面３２に接触して押すように構成されている。また、電池収容部２３に電池３が収容された状態では、抑えばね１３が元の状態（図６Ａに示す状態）に復帰しようとすることにより、抑えばね１３の弾性力が絶縁部材２３３を介して電池３の第２面３２に加わる。 When the battery 3 is housed in the battery accommodating portion 23, the insulating member 233 tries to return to the original state (the state shown in FIG. 6A), so that the elastic force of the insulating member 233 is reduced to the second surface 32 of the battery 3. Join in. In other words, the insulating member 233 is configured to contact and push the second surface 32 of the battery 3 in a state where the battery 3 is housed in the battery housing portion 23. Further, in the state where the battery 3 is housed in the battery housing portion 23, the holding spring 13 tries to return to the original state (the state shown in FIG. 6A), so that the elastic force of the holding spring 13 passes through the insulating member 233. It joins the second surface 32 of the battery 3.

したがって、電池３は、絶縁部材２３３及び抑えばね１３と、周壁２３２との間で抑えられることにより、電池収容部２３に保持される。このように、本実施形態では、電池収容部２３に電池３が保持されることにより、車両１００の振動に伴って電池３が振動するのを抑えることができる。これにより、本実施形態では、電池３が振動することによる接続端子１１，１２と電池３の電極３３，３４との接触不良を防ぎやすい。また、これにより、本実施形態では、電池３が振動することによる共鳴音（異音）の発生を防ぎやすい。 Therefore, the battery 3 is held by the battery accommodating portion 23 by being suppressed between the insulating member 233 and the holding spring 13 and the peripheral wall 232. As described above, in the present embodiment, the battery 3 is held in the battery accommodating portion 23, so that the battery 3 can be suppressed from vibrating with the vibration of the vehicle 100. Thereby, in the present embodiment, it is easy to prevent poor contact between the connection terminals 11 and 12 and the electrodes 33 and 34 of the battery 3 due to the vibration of the battery 3. Further, in this embodiment, it is easy to prevent the generation of resonance sound (abnormal noise) due to the vibration of the battery 3.

本実施形態では、絶縁部材２３３が電池３の第２面３２を押す位置と、抑えばね１３が電池３の第２面３２を間接的に押す位置とは、同じである。言い換えれば、抑えばね１３は、電池収容部２３に電池３が収容された状態で、絶縁部材２３３が電池３の第２面３２を押す位置を、絶縁部材２３３を介して押すように構成されている。 In the present embodiment, the position where the insulating member 233 pushes the second surface 32 of the battery 3 and the position where the holding spring 13 indirectly pushes the second surface 32 of the battery 3 are the same. In other words, the holding spring 13 is configured to push the position where the insulating member 233 pushes the second surface 32 of the battery 3 via the insulating member 233 while the battery 3 is housed in the battery housing portion 23. There is.

また、本実施形態では、絶縁部材２３３及び抑えばね１３は、電池収容部２３に電池３が収容された状態で、電池３の第２面３２に直交する方向（電池３の径方向）にて第２面３２を押すように構成されている。つまり、本実施形態では、絶縁部材２３３及び抑えばね１３は、電池３の径方向において、周壁２３２との間で電池３を抑えている。 Further, in the present embodiment, the insulating member 233 and the holding spring 13 are arranged in a direction orthogonal to the second surface 32 of the battery 3 (in the radial direction of the battery 3) in a state where the battery 3 is housed in the battery accommodating portion 23. It is configured to push the second surface 32. That is, in the present embodiment, the insulating member 233 and the holding spring 13 hold the battery 3 together with the peripheral wall 232 in the radial direction of the battery 3.

また、本実施形態では、抑えばね１３及び絶縁部材２３３は、電池収容部２３に電池３が収容された状態で、電池３の軸方向（上下方向）の中央部を押すように構成されている。つまり、抑えばね１３は、電池収容部２３に電池３が収容された状態で、抑えばね１３から電池３を見たときの電池３の第２面３２の中央部を押すように構成されている。 Further, in the present embodiment, the holding spring 13 and the insulating member 233 are configured to push the central portion of the battery 3 in the axial direction (vertical direction) in a state where the battery 3 is accommodated in the battery accommodating portion 23. .. That is, the holding spring 13 is configured to push the central portion of the second surface 32 of the battery 3 when the battery 3 is viewed from the holding spring 13 in a state where the battery 3 is housed in the battery housing portion 23. ..

Further, in the present embodiment, since the step of manufacturing the dedicated spring member is unnecessary, the manufacturing process of the vehicle-mounted device 1 can be simplified, and there is an advantage that the vehicle-mounted device 1 can be easily manufactured. .. Further, in the present embodiment, the number of parts can be reduced and the manufacturing process of the in-vehicle device 1 can be simplified, and as a result, there is an advantage that the manufacturing cost can be easily reduced.

なお、電池収容部２３の凹所２３０の径寸法を電池３の径寸法と略同じにすることで、ケース２の周壁２３２のみで電池３を抑える構成も考えられる。しかしながら、この構成では、電池収容部２３に電池３を挿入する際に、電池３が周壁２３２に接触しながら擦り動くことで、電池３の絶縁被覆を傷つける可能性がある。一方、本実施形態では、凹所２３０の径寸法を電池３の径寸法と略同じにすることなく、抑えばね１３により電池３を電池収容部２３にて十分に保持することが可能である。このため、本実施形態では、上記のような問題が生じにくい。 By making the diameter dimension of the recess 230 of the battery accommodating portion 23 substantially the same as the diameter dimension of the battery 3, it is conceivable that the battery 3 is suppressed only by the peripheral wall 232 of the case 2. However, in this configuration, when the battery 3 is inserted into the battery accommodating portion 23, the battery 3 rubs while contacting the peripheral wall 232, which may damage the insulating coating of the battery 3. On the other hand, in the present embodiment, the battery 3 can be sufficiently held by the battery accommodating portion 23 by the holding spring 13 without making the diameter dimension of the recess 230 substantially the same as the diameter dimension of the battery 3. Therefore, in the present embodiment, the above-mentioned problems are unlikely to occur.

As described above, the vehicle-mounted device (1) according to the first aspect includes a battery accommodating portion (23), a connection terminal (first connection terminal) (11), and a holding spring (13). The battery accommodating portion (23) is provided in the case (2) and can accommodate the battery (3). The battery (3) is electrically insulated from the electrode (33) by intersecting the first surface (31) provided with an electrode (negative electrode) (33) at one end in the axial direction and the first surface (31). It has a second surface (32). The connection terminal (11) contacts the electrode (33) of the battery (3) with the battery (3) housed in the battery housing (23) to electrically attach the battery (3) to the substrate (4). Connect to. The holding spring (13) has a wall (peripheral wall (peripheral wall (peripheral wall)) in which the second surface (32) of the battery (3) is a part of the case (2) in a state where the battery (3) is housed in the battery housing portion (23). 232)) and suppress it. The connection terminal (11) is integrated with the holding spring (13).

この態様によれば、車載デバイス（１）の電池格納構造において、電池（３）を抑えるための専用のばね部材が不要であるので、部品点数を削減することができる、という利点がある。 According to this aspect, in the battery storage structure of the in-vehicle device (1), since a dedicated spring member for holding down the battery (3) is not required, there is an advantage that the number of parts can be reduced.

第２の態様に係る車載デバイス（１）は、第１の態様において、絶縁部材（２３３）を更に備える。絶縁部材（２３３）は、電池収容部（２３）に電池（３）が収容された状態で、電池（３）の第２面（３２）と抑えばね（１３）との間に位置する。 The vehicle-mounted device (1) according to the second aspect further includes an insulating member (233) in the first aspect. The insulating member (233) is located between the second surface (32) of the battery (3) and the holding spring (13) in a state where the battery (3) is housed in the battery housing portion (23).

この態様によれば、第１接続端子（１１）の抑えばね（１３）と、電池（３）との間の電気的な絶縁性を十分に確保しやすい、という利点がある。 According to this aspect, there is an advantage that it is easy to sufficiently secure the electrical insulation between the holding spring (13) of the first connection terminal (11) and the battery (3).

第３の態様に係る車載デバイス（１）では、第２の態様において、絶縁部材（２３３）は、樹脂製のばねである。絶縁部材（２３３）は、ケース（２）と一体である。 In the vehicle-mounted device (1) according to the third aspect, in the second aspect, the insulating member (233) is a resin spring. The insulating member (233) is integrated with the case (2).

この態様によれば、抑えばね（１３）のみで電池（３）を抑える構成と比較して、接続端子（第１接続端子）（１１）と電池（３）との間の電気的な絶縁性を確保しやすい、という利点がある。すなわち、抑えばね（１３）のみで電池（３）を抑える構成では、金属製の抑えばね（１３）が直接、電池（３）の第２面（３２）に接触することから、電池（３）と接続端子（第１接続端子）（１１）との間の電気的な絶縁性を確保しにくい。一方、絶縁部材（２３３）のみで電池（３）を抑える構成では、絶縁部材（２３３）の経年劣化により、抑えばね（１３）と比較して電池（３）を抑える効果が持続しにくい。この態様によれば、抑えばね（１３）及び絶縁部材（２３３）の両者を用いた構成であるため、両者の欠点を補いつつ、電池（３）を抑えることが可能になる、という利点がある。また、この態様によれば、ケース（２）の一部が絶縁部材（２３３）を兼ねているので、絶縁部材（２３３）を専用品として製造する必要がなく、電池格納構造において、部品点数を削減することができる、という利点がある。 According to this aspect, the electrical insulation between the connection terminal (first connection terminal) (11) and the battery (3) is compared with the configuration in which the battery (3) is suppressed only by the holding spring (13). There is an advantage that it is easy to secure. That is, in the configuration in which the battery (3) is suppressed only by the holding spring (13), the metal holding spring (13) directly contacts the second surface (32) of the battery (3), so that the battery (3) It is difficult to secure the electrical insulation between the connection terminal (first connection terminal) (11) and the connection terminal (first connection terminal) (11). On the other hand, in the configuration in which the battery (3) is suppressed only by the insulating member (233), the effect of suppressing the battery (3) is less likely to be sustained as compared with the holding spring (13) due to the aged deterioration of the insulating member (233). According to this aspect, since the configuration uses both the holding spring (13) and the insulating member (233), there is an advantage that the battery (3) can be held down while compensating for the shortcomings of both. .. Further, according to this aspect, since a part of the case (2) also serves as the insulating member (233), it is not necessary to manufacture the insulating member (233) as a dedicated product, and the number of parts can be increased in the battery storage structure. It has the advantage that it can be reduced.

第４の態様に係る車載デバイス（１）では、第２または第３の態様において、抑えばね（１３）は、電池収容部（２３）に電池（３）が収容された状態で、絶縁部材（２３３）が電池（３）の第２面（３２）を押す位置を、絶縁部材（２３３）を介して押すように構成されている。 In the in-vehicle device (1) according to the fourth aspect, in the second or third aspect, the holding spring (13) is an insulating member (13) in a state where the battery (3) is accommodated in the battery accommodating portion (23). The position where the 233) pushes the second surface (32) of the battery (3) is configured to push through the insulating member (233).

この態様によれば、絶縁部材（２３３）が電池（３）の第２面（３２）を押す位置と、抑えばね（１３）が電池（３）の第２面（３２）を間接的に押す位置とは、同じである。このため、この態様によれば、抑えばね（１３）が絶縁部材（２３３）の変形による影響を受けにくいことから、抑えばね（１３）が電池（３）を抑えるための弾性力を失いにくい、という利点がある。 According to this aspect, the position where the insulating member (233) pushes the second surface (32) of the battery (3) and the holding spring (13) indirectly push the second surface (32) of the battery (3). The position is the same. Therefore, according to this aspect, since the holding spring (13) is not easily affected by the deformation of the insulating member (233), the holding spring (13) is unlikely to lose the elastic force for holding the battery (3). There is an advantage.

第５の態様に係る車載デバイス（１）では、第２または第３の態様において、絶縁部材（２３３）は、電池収容部（２３）に電池（３）が収容された状態で、電池（３）の第２面（３２）に接触して押すように構成されている。 In the vehicle-mounted device (1) according to the fifth aspect, in the second or third aspect, the insulating member (233) is a battery (3) in a state where the battery (3) is housed in the battery housing portion (23). ) Is configured to come into contact with and push the second surface (32).

この態様によれば、電池収容部（２３）に電池（３）が収容された状態で、絶縁部材（２３３）は、抑えばね（１３）の有無に依らず、単体でも電池（３）を抑えるための弾性力を発生している。このため、この態様によれば、抑えばね（１３）のみで電池（３）を抑える場合と比較して、より強い力で電池（３）を抑えることが可能になる、という利点がある。 According to this aspect, in a state where the battery (3) is housed in the battery housing portion (23), the insulating member (233) holds down the battery (3) by itself regardless of the presence or absence of the holding spring (13). Is generating elastic force. Therefore, according to this aspect, there is an advantage that the battery (3) can be suppressed with a stronger force as compared with the case where the battery (3) is suppressed only by the holding spring (13).

第６の態様に係る車載デバイス（１）では、第１〜第５のいずれかの態様において、抑えばね（１３）は、電池収容部（２３）に電池（３）が収容された状態で、電池（３）の第２面（３２）と直交する方向にて第２面（３２）を押すように構成されている。 In the vehicle-mounted device (1) according to the sixth aspect, in any one of the first to fifth aspects, the holding spring (13) has the battery (3) housed in the battery housing section (23). It is configured to push the second surface (32) in a direction orthogonal to the second surface (32) of the battery (3).

この態様によれば、上記方向以外の方向にて第２面（３２）を押す場合と比較して、抑えばね（１３）の弾性力が電池（３）の第２面（３２）に伝わりやすく、抑えばね（１３）と壁（周壁（２３２））との間で電池（３）を抑えやすい、という利点がある。 According to this aspect, the elastic force of the holding spring (13) is more easily transmitted to the second surface (32) of the battery (3) as compared with the case where the second surface (32) is pushed in a direction other than the above direction. There is an advantage that the battery (3) can be easily held between the holding spring (13) and the wall (peripheral wall (232)).

第７の態様に係る車載デバイス（１）では、第１〜第６のいずれかの態様において、抑えばね（１３）は、電池収容部（２３）に電池（３）が収容された状態で、抑えばね（１３）から電池（３）を見たときの電池（３）の第２面（３２）の中央部を押すように構成されている。 In the vehicle-mounted device (1) according to the seventh aspect, in any one of the first to sixth aspects, the holding spring (13) has the battery (3) housed in the battery housing section (23). It is configured to push the central portion of the second surface (32) of the battery (3) when the battery (3) is viewed from the holding spring (13).

この態様によれば、抑えばね（１３）が電池（３）の第２面（３２）の中央部以外の位置を押す場合と比較して、安定して抑えばね（１３）と壁（周壁（２３２））との間で電池（３）を抑えやすい、という利点がある。すなわち、抑えばね（１３）が電池（３）の第２面（３２）の中央部以外の位置を押す場合、電池（３）に不要なモーメントが掛かりやすくなる可能性がある一方、この態様では、そのような事象が生じにくい。また、この態様によれば、抑えばね（１３）が電池（３）の第２面（３２）の中央部を押すため、他の位置を押す場合と比較して、小さい弾性力により抑えばね（１３）と壁（周壁（２３２））との間で電池（３）を抑えやすい、という利点がある。 According to this aspect, the holding spring (13) and the wall (peripheral wall (peripheral wall (peripheral wall)) are more stable than the case where the holding spring (13) pushes a position other than the central portion of the second surface (32) of the battery (3). There is an advantage that the battery (3) can be easily suppressed between the 232)) and the battery (3). That is, when the holding spring (13) pushes a position other than the central portion of the second surface (32) of the battery (3), an unnecessary moment may be easily applied to the battery (3), but in this embodiment, , Such an event is unlikely to occur. Further, according to this aspect, since the holding spring (13) pushes the central portion of the second surface (32) of the battery (3), the holding spring (13) has a smaller elastic force than the case of pushing the other positions. There is an advantage that the battery (3) can be easily suppressed between the wall (13) and the wall (peripheral wall (232)).

第２〜第７の態様に係る構成については、車載デバイス（１）に必須の構成ではなく、適宜省略可能である。 The configurations according to the second to seventh aspects are not essential configurations for the in-vehicle device (1) and can be omitted as appropriate.
