Description

【０００１】
【発明の属する技術分野】
本発明は、自動車の電池搭載装置に関し、特に電気自動車やハイブリッド自動車の電池搭載装置に関する。
【０００２】
【従来の技術】
一般に電気自動車やハイブリッド自動車は、その電源として比較的軽量で車載性に優れることから、例えばリチウムイオン等を構成主材料とする筒型の高性能電池を複数本組み合わせて用いられている。
【０００３】
しかし、この高性能電池は、過放電及び過充電の際の発熱量が比較的大きく、このため車載にあたっては充分な冷却を行う必要があり、この対策として特開平８−３１０２５５号公報に開示される先行技術がある。
【０００４】
この先行技術には、図９に斜視図を示すように、横板材１０２と縦板材１０３とにより井桁状の電池載架棚１０１を形成すると共に、横板材１０２と縦板材１０３の各交差部に、横板材１０２と縦板材１０３に跨る電池収容窓１０４を形成し、各電池収容窓１０４に円柱状に形成された筒型電池１０５を嵌合収容し、この筒型電池１０５を嵌合収容した電池載架棚１０１を車体部材に締結固定する電気自動車の電池搭載装置が開示されている。
【０００５】
【発明が解決しようとする課題】
上記先行技術によると、電池載架棚の横板材と縦板材との交差部に形成した電池収容窓に筒型電池を嵌合して配置し、しかも電池載架棚が井桁状に形成されることから、筒型電池がその軸方向に流通する冷却風に晒されて冷却される。
【０００６】
しかし、井桁状に形成された板材によって筒型電池の外周面を軸方向に亘って固定することから、筒型電池の軸方向に沿って比較的長く、しかも狭く冷却風通路が形成されて充分な冷却効果が得難く、また筒型電池の長さや外形が異なる場合には、各電池の外形寸法に相応した電池収容窓を有する電池載架棚を準備する必要があり、汎用性に乏しいものである。
【０００７】
一方、平板状の縦板材及び横板材に開口する電池収容窓の縁部のみによって筒型電池を固定することから、筒型電池を保持するための充分な固定強度の確保が困難であり、特に筒型電池の側面方向から衝撃等の力が作用した際に、筒型電池が移動して端子間の短絡等の電気的不具合を誘発するおそれがある。更に電池載架棚が井桁状に形成されることに起因して、電池載架棚それ自体が側面方向からの荷重に対して充分な強度が得られないおそれがある。
【０００８】
この対策として、各板材の板圧を増すと、更に冷却風通路が狭くなり冷却効果が低下しかつ重量の増加を招くことになる。
【０００９】
かかる点に鑑みなされた本発明の目的は、冷却効果及び汎用性に優れ、かつ充分な強度が確保できる自動車の電池搭載装置を提供することにある。
【００１０】
【課題を解決するための手段】
上記目的を達成する請求項１に記載の発明は、一対のケース本体と、該一対のケース本体を互いに離間させて連結する連結軸部材とから構成し、上記離間するケース本体の互いに対向する内側面には電池の端子側端部を嵌合保持する嵌合部を設け、上記ケース本体の外側面には、上記電池の端子を上記ケース本体から突出させる端子挿通孔を設けた自動車の電池搭載装置において、上記ケース本体には、電気絶縁材によって形成され、上記外側面から突出した上記端子を囲む収容部を形成するフランジ部を突設すると共に、上記ケース本体に取付可能でかつ、上記フランジ部の先端に当接して上記収容部を覆う電気絶縁材から形成された蓋を具備することを特徴とする。
【００１１】
この請求項１に記載の発明によると、電池の両端部のみがケース本体の嵌合部に嵌合して保持されることから、電池の広範囲が冷却風に晒され、しかも冷却風通路が電池の外周面に沿って形成されて充分な冷却効果が得られる。
【００１２】
また各ケース本体間が連結軸部材によって互いに一体的に固定されると共に、各ケース本体の嵌合部に両端が嵌合して両ケース本体間に掛け渡された状態で電池が強固に固定されることから衝撃等の荷重に対して電池の固定強度、及び電池搭載装置の強度が確保できる。
【００１３】
更に、ケース本体に保持された電池の端子及び端子間を接続する配線材等がケース本体に突設されたフランジ部及び蓋によって密閉された収容部内に収納でき、外部からの衝撃に対して端子等が保護されて短絡や破損が防止されると共に、端子等は外部から電気絶縁処理及び防水処理がなされ安全性が向上し、かつ端子等が搬送や車載作業中に、作業者に直接触れることが回避されて作業の安全性が向上する。
【００１４】
請求項２に記載の発明は、請求項１に記載の発明において、上記フランジ部には、上記端子への配線用のスリット部を設けたことを特徴とする。このスリット部を介して挿通される接続線によって他のユニットに容易に接続できる。
【００１５】
請求項３に記載の発明は、請求項１または２に記載の発明において、上記ケース本体には、上記収容部内を区画形成する区画壁を突設したことを特徴とする。
【００１６】
この請求項３に記載の発明によると、収容部内を区画壁によって区画することによって、区画壁によって区画された中に電池電圧や電池温度を管理するコントローラを収容配置することが可能になり、電池に取り付けられたセンサとコントローラとの間の配線が極めて短くなると共に、作業空間が容易に確保可能な車載前において予め配線作業ができ、その作業性に優れ、かつ外部からの衝撃に対して端子等がより確実に保護される。
【００１７】
請求項４に記載の発明は、一対のケース本体と、該一対のケース本体を互いに離間させて連結する連結軸部材とから構成し、上記離間するケース本体の互いに対向する内側面には電池の端子側端部を嵌合保持する嵌合部を設け、上記ケース本体の外側面には、上記電池の端子を上記ケース本体から突出させる端子挿通孔を設けた自動車の電池搭載装置において、上記電池の端子には、電気絶縁材から形成された端子カバー部材を設け、上記端子カバー部材には配線用のスリットを開口させたことを特徴とする。
【００１８】
請求項４の発明によると、電池の両端部のみがケース本体の嵌合部に嵌合して保持されることから、電池の広範囲が冷却風に晒され、しかも冷却風通路が電池の外周面に沿って形成されて充分な冷却効果が得られる。また各ケース本体間が連結軸部材によって互いに一体的に固定されると共に、各ケース本体の嵌合部に両端が嵌合して両ケース本体間に掛け渡された状態で電池が強固に固定されることから衝撃等の荷重に対して電池の固定強度、及び電池搭載装置の強度が確保できる。更に、各端子等は外部から電気絶縁及び防水処理がなされ安全性が向上すると共に、外部からの衝撃に対しても端子等が保護されて短絡や破損が未然に回避されるものである。
【００１９】
【発明の実施の形態】
以下、本発明による電気自動車やハイブリッド自動車等に用いられる自動車の電池搭載装置の実施形態を図によって説明する。
【００２０】
（参考例）
本発明における自動車の電池搭載装置の参考例を、電池が筒型電池の場合を例に図１乃至図３によって説明する。
【００２１】
図１は、電池搭載装置１の斜視図であり、電池搭載装置１は、一対のケース本体１０及び、両ケース本体１０を一体的に連結する連結軸部材２０を有している。
【００２２】
各ケース本体１０は、合成樹脂等の電気絶縁材からなり下面が平坦なブロック状であって、各ケース本体１０の相対向する内側面１１には、搭載すべき筒型電池Ｂの円筒部Ｂａの端部Ｂｂが嵌挿可能な複数個、本参考例では各々６個の嵌合部１４が各々離間し、かつ両ケース本体１０間において対向して凹設されている。
【００２３】
これらの嵌合部１４は、図２に図１のＩ−Ｉ線断面を示すように筒型電池Ｂの円筒部Ｂａが嵌合可能な内径Ｄを有する有底の円筒状であって、その底部１４ａには上記端部Ｂｂから円筒状の端子ベース部Ｂｃを介して同軸上に突出する端子Ｂｄを挿通する端子挿通孔１５が開口し、嵌合部１４に嵌挿した筒型電池Ｂの端子Ｂｄの先端が端子挿通孔１５を介してケース本体１０の外側面１２に突出するように形成されている。
【００２４】
なお、図２中符号１６は、上記嵌合部１４の底部１４ａと筒型電池Ｂの円筒部Ｂａの端部Ｂｂとの間に介装されて筒型電池Ｂを保持する円板状のガスケットである。
【００２５】
更に、各ケース本体１０には、内側面１１から外側面１２に貫通する複数の連結軸係合孔１７が穿設されている。
【００２６】
連結軸係合孔１７は、図３に図１のＩＩ−ＩＩ線断面を示すように、内向面１１に開口して連結軸取付ボルト２２と共に連結軸部材２０を構成する連結軸２１の端部２１ａが嵌入する連結軸挿入部１７ａと、この連結軸挿入部１７ａに挿入された連結軸２１の端部２１ａに当接して連結軸２１の挿入量を規制する区画部１７ｂと、外側面１２に開口して連結軸取付ボルト２２の頭部２２ａの挿入を許容するボルト挿入部１７ｃと、区画部１７ｂに形成されて連結軸取付ボルト２２のねじ部２２ｂの挿入を可能にするねじ部挿通部１７ｄを有し、これら連結軸挿入部１７ａ、ボルト挿入部１７ｃ及びねじ部挿通部１７ｄが共に同軸上に形成されている。
【００２７】
そして、内側面１１側から連結軸挿入部１７ａに挿入された連結軸２１は、区画部１７ｂの端部に当接して連結軸２１の挿入量が規制され、ボルト挿入部１７ｃに挿入された連結軸取付ボルト２２のねじ部２２ｂがねじ部挿通部１７ｄを貫通し、連結軸２１のねじ穴２１ｂに螺合することによって連結軸部材２０とケース本体１０とを結合することによって両ケース本体１０間の相対位置が決められると共に、一体化が得られるように構成されている。
【００２８】
更に各ケース本体１０の上部には、治具係止部１８ａが架設された搬送治具取付穴１８が形成されると共に、ケース本体１０の外側面１２の下端両側にはケース本体１０を車体部材（図示せず）に固定用ボルト２３によって取り付けるためのボルト挿通孔１９ａ（図４、図６等参照）を有する取付部１９が突設されている。
【００２９】
図中符号２４は、端子挿通孔１５からケース本体１０の外側面１２に突出した筒型電池Ｂの端子Ｂｄ間を接続する配線材であり、配線材２４の両端に開口する端子係止孔（図示せず）を端子Ｂｄに嵌合してナット２５によって端子Ｂｄに取り付けられる。
【００３０】
一方、この電池搭載装置１を搬送するための搬送治具３０は、棒状の握持部３０ａと、この握持部３０ａの両端にフック状に形成され、上記搬送治具取付穴１８の治具係止部１８ａに係止可能な係合部３０ｂとにより構成されている。
【００３１】
このように構成される電池搭載装置１の組立について説明する。
【００３２】
各内側面１１が互いに対向するように一対のケース本体１０を離間して配置する。そして、各筒型電池Ｂの端子Ｂｄにガスケット１６を装着し、円筒部Ｂａの両端部Ｂｂを各々対向する各ケース本体１０の嵌合部１４に挿入せしめ、端子Ｂｄの先端を端子挿通孔１５から外側面１２側に突出させると共に、各連結軸２１の両端２１ａを各ケース本体１０に形成された各々の連結軸係合孔１７の連結軸挿入部１７ａに挿入する。
【００３３】
続いて、連結軸取付ボルト２２をボルト挿入部１７ｃから挿入し、ねじ部２２ｂを連結軸２１のねじ穴２１ｂに螺合することによって連結軸２１の端部２１ａが区画部１７ｂの端部に圧接してケース本体１０と連結軸２１の相対位置決めがなされ、連結軸２１とケース本体１０、換言すると互いのケース本体１０が連結軸部材２０によって相対位置決めがなされると共に、一体的に結合される。
【００３４】
この連結軸取付ボルト２２による連結軸２１の取り付けによる締め付けによって、嵌合部１４に挿入された筒型電池Ｂの端部Ｂｂがガスケット１６を介して底部１４ａに押し付けられる。
【００３５】
従って、筒型電池Ｂは、その軸方向の移動がガスケット１６を介して底部１４ａによって、また周方向の移動が嵌合部１４の内周面１４ｂによって規制されて両ケース本体１０によって両側から挟持された状態で保持される。
【００３６】
そして、配線材２４の両端に開口する端子係止孔を外側面１２から突出した筒型電池Ｂの端子Ｂｄに嵌合させ、ナット２５により配線材２４を端子Ｂｄに取り付けることにより、隣設する筒型電池Ｂの両端子Ｂｄ間が配線材２４によって連結される。
【００３７】
このようにして組み立てられた電池搭載装置１は、両ケース本体１０の上部に各々形成された搬送治具取付穴１８の治具係止部１８ａに各々搬送治具３０の両端に形成された係合部３０ｂを係止して、棒状の握持部３０ａを持って容易に搬送可能であり、車体部材の搭載部上に搬入載置し、取付部１９のボルト装通孔１９ａに挿入される固定用ボルト２３によって車体部材に固定される。
【００３８】
従って参考例によると、ケース本体１０に嵌合部１４を凹設することによって嵌合部１４が容易に形成でき、複数の筒型電池Ｂが互いに離間して配置されると共に、その両端部Ｂｂの近傍部分のみが各々ケース本体１０の嵌合部１４に嵌合して保持されることから、隣設する筒型電池Ｂが互いに離間して配置され、筒型電池Ｂの円筒部Ｂａ外周面に沿って冷却風通路が形成されて円筒部Ｂａの広範囲が冷却風に晒され、充分な冷却効果が得られる。
【００３９】
また、筒型電池Ｂは、複数の連結軸部材２０によって互いに一体的に固定された各ケース本体１０の嵌合部１４に両端部Ｂｂが嵌合して強固に固定されると共に、ケース本体１０の下面が平面状に形成されて固定用ボルト２３によって車体部材に取り付けられることから安定した状態で車体部材上に載置固定できて車載性に優れ、衝撃等の荷重に対しても充分な強度が確保できる。
【００４０】
更に、軸方向の長さ、すなわち円筒部Ｂａの寸法が相違する筒型電池Ｂに対しても、長さの異なる連結軸２１を用いることにより容易に対処することが可能であり、各ケース本体１０等の共用化が得られて汎用性に優れるものである。
【００４１】
（第１実施形態）
本発明による電気自動車の電池搭載装置の第１実施形態を図４及び図５によって説明する。なお説明の便宜上図１乃至図３と対応する部分に同一符号を付すことにより詳細な説明は省略する。
【００４２】
図４は、ケース本体１０の斜視図であって、図５はケース本体１０に筒型電池Ｂ、配線材２４等を取り付けた状態における図４のＩＩＩ−ＩＩＩ線断面図である。
【００４３】
本実施形態におけるケース本体１０の外側面１２には、全ての端子挿通孔１５、端子Ｂｄ及び各端子Ｂｄ間を連結する配線材２４等を囲むように、ケース本体１０と一体に形成されるフランジ部３１が略矩形に突設され、外側面１２及びフランジ部３１によって端子等収容部３２を形成している。
【００４４】
フランジ部３１の高さＨは、端子挿通孔１５を介してケース本体１０の外側面１２から突出した端子Ｂｄに端子係止孔２４ａを嵌合して配線材２４等を取り付けた状態における外側面１２から突出する最大高さ、本実施形態においては外側面１２から端子Ｂｄの頂部までの高さより大なるように設定されている。
【００４５】
このフランジ部３１の一部には、スリット部３３が切り欠き形成され、スリット部３３の内周面には接続線（図示せず）を挿通させるガスケット（図示せず）を係止する係止溝３３ａが形成されると共に、フランジ部３１の上部及び下部には各々２個の蓋取付ねじ穴３４が形成されている。
【００４６】
更に、フランジ部３１の頂部３１ａに当接して上記端子等収容部３２を密閉被覆する絶縁材料製の蓋３５を有し、この蓋３５は蓋取付ボルト３６によって蓋取付ねじ穴３４にボルト止めされるように構成されている。
【００４７】
このように構成される第１実施形態によると、上記した参考例の効果に加え、ケース本体１０に保持された筒型電池Ｂの端子Ｂｄ及び、端子Ｂｄ間を接続する配線材２４等がケース本体１０に突設されたフランジ部３１及び蓋３５によって密閉された端子等収容部３２内に収納され、かつ他のユニットへ接続するための接続線はスリット部３３に設けられたガスケットを挿通して取り出されることから、端子Ｂｄ、配線材２４等は外部から電気絶縁及び防水処理がなされ安全性が向上する。
【００４８】
なお、万一筒型電池Ｂの円筒部Ｂａと嵌合部１４の内周面１４ｂとの間から水滴等の浸入があっても、筒型電池Ｂの端部Ｂｂと底部１４ａとの間に介在するガスケット１６によって端子等収容部３２内に入り込むことはない。
【００４９】
一方、端子Ｂｄ及び配線材２４等が、フランジ部３１及び蓋３５によって覆われ、搬送や車載作業中に作業者に直接触れることが回避されて作業の安全性が向上する。
【００５０】
更に、外部からの衝撃に対しても端子Ｂｄ及び配線材２４等の端子等収容部３２内の収容物は、フランジ部３１及び蓋３５によって保護されて短絡や破損が未然に回避される等の効果を有する。
【００５１】
なお、端子等収容部３２からの接続線の取り出しが不要な場合には、スリット部３３を封止用グロメット（図示せず）により封止することによって端子等収容部３２内の防水効果は維持される。
【００５２】
（第２実施形態）
本発明による電気自動車の電池搭載装置の第２実施形態を図６によって説明する。なお説明の便宜上図４及び図５に対応する部分に同一符号を付すことにより詳細な説明は省略する。
【００５３】
図６は、ケース本体１０の斜視図であって、図４及び図５に示す上記第１実施形態に対し、フランジ部３１で囲まれた上記端子等収容部３２内に、区画壁３６によってコントローラ等収容部３７を区画形成した点で異なる。
【００５４】
区画壁３６は、フランジ部３１に連続してケース本体１０の外側面１２に突設形成されて前記複数形成された端子挿通孔１５の間に、端子Ｂｄ及び配線材２４等との接触を回避して各種センサやコントローラ（図示せず）等を収納するためのコントローラ等収容部３７を区画形成している。
【００５５】
区画壁３６の高さｈは、その頂部３６ａが、端子等収容部３２を密閉被覆する上記蓋３５の内面に当接するように設定され、上記蓋３５によってコントローラ等収容部３７内を更に密閉するように形成されている。
【００５６】
従って、コントローラ等収容部３７内に電池電圧や電池温度を管理するコントローラを収容配置することにより、筒型電池Ｂに取り付けられたセンサとコントローラとの間の配線が、コントローラを車体等に設けた配置に比べて極めて短くすることが可能になる。一方、電池搭載装置１の車載前において配線等が可能であり、従ってその作業空間が容易に確保され、電池搭載装置１を車載した後の配線作業に比べ、格段に作業性が向上する。
【００５７】
また、区画壁３６の頂部３６ａが蓋３５の内面に当接して蓋３５を支持することから、第１実施形態に比べ、更に外部からの衝撃に対して端子Ｂｄ、配線材２４、コントローラ等が蓋３５及びフランジ部３１、区画壁３６等によってより確実に保護されて短絡や破損がより確実に回避される。
【００５８】
（第３実施形態）
本発明による電気自動車の電池搭載装置の第３実施形態を図７によって説明する。なお説明の便宜上図１及び図３に対応する部分に同一符号を付すことにより詳細な説明は省略する。
【００５９】
図７において符号４０は端子カバー部材であって、端子カバー部材４０は電気絶縁材からなる例えば合成樹脂製で円筒状の端子カバー４１とキャップ４２とを有し、端子カバー４１の側部には配線材２４の端部が挿入可能な配線材用スリット４１ａが開口すると共に、基端側内周に沿ってＯリング係止溝４１ｂが形成されている。
【００６０】
そして、Ｏリング係止溝４１ｂにＯリング４３を係止し、端子カバー４１の基端側をケース本体１０に開口する端子挿通孔１５から挿入して筒型電池Ｂの端子ベース部Ｂｃに嵌合することによって、端子カバー４１はＯリング４３を介して筒型電池Ｂの端子ベース部Ｂｃに取り付けられ、端子カバー４１の先端はキャップ４２によって封鎖されるよう構成されている。
【００６１】
更に端子カバー４１の配線材用スリット４１ａと配線材２４との隙間は、例えば環状のゴム製等のシール部材（図示せず）が介装されて防水処理が施されている。
【００６２】
このように構成される端子カバー部材４０等を装着するには、端子カバー４１のＯリング係止溝４１ｂにＯリング４３を係止すると共に、配線材２４に上記一対のシール部材を嵌装する。そして一対の端子カバー４１に開口する各配線材用スリット４１ａから配線材２４の両端を各々挿入して準備する。
【００６３】
次に、各端子カバー４１の基端部側を、予め筒型電池Ｂが組み付けられたケース本体１０の端子挿通孔１５から挿入し、各端子カバー４１の基端部側を端子ベース部Ｂｃに嵌合せしめ、端子カバー４１をＯリング４３を介して筒型電池Ｂの端子ベース部Ｂｃに取り付けると同時に、配線材用スリット４１ａから端子カバー４１内に突出する配線材２４の各先端に開口する端子係止孔２４ａを端子Ｂｄに嵌合する。
【００６４】
続いて、配線材２４の端子係止孔２４ａから突出する端子Ｂｄにナット２５を螺合せしめて配線材２４を端子Ｂｄに取り付けることにより、隣設する筒型電池Ｂの両端子Ｂｄ間を配線材２４によって連結する。
【００６５】
そして、配線材２４に嵌装されたシール部材を移動せしめて端子カバー４１の配線材用スリット４１ａと配線材２４との間に押し込み、配線材用スリット４１ａと配線材２４との間の隙間をシール部材によって封止し、かつ端子カバー４１の先端をキャップ４２によって封止する。
【００６６】
従って本実施形態によると、参考例に加え、各端子Ｂｄが端子カバー４１及びキャップ４２によって密閉されることから、端子Ｂｄ等は外部から電気絶縁及び防水処理がなされ安全性が向上すると共に、外部からの衝撃に対しても端子Ｂｄ及び配線材２４等は端子カバー４１及びキャップ４２によって保護されて短絡や破損が未然に回避される。
【００６７】
また、端子カバー４１は端子ベース部Ｂｃに取り付ける際に、その取付の方向性がなく、同一形状の端子カバー４１によって配線材２４による種々の配線のレイアウトに対処することが可能である。なお端子ベース部Ｂｃの外周にもＯリング係止溝を形成することによりＯリング４３を介しての端子カバー４１の取り付けをより確実にすることも可能である。
【００６８】
更に、キャップ４２を装着した端子カバー４１を、ケース本体１０にかかわらず筒型電池Ｂに単独で付けることも可能であり、組立持や搬送等に電池Ｂを単独で取り扱う際にも絶縁カバーとして使用でき、作業者の作業安全性が確保できる等の効果を有する。
【００６９】
（第４実施形態）
本発明による電気自動車の電池搭載装置の第４実施形態を図８によって説明する。なお説明の便宜上図１及び図３に対応する部分に同一符号を付すことにより詳細な説明は省略する。
【００７０】
図８中において符号４４は、端子カバー部材であって、この端子カバー部材４４は電気絶縁材、例えば合成樹脂製の端子カバー４５及びキャップ４６を有し、端子カバー４５は円筒状で側部には配線材２４の端部が挿入可能な配線材用スリット４５ａが開口すると共に、基端側外周に沿って円盤状の係止フランジ部４５ｂが突設されている。
【００７１】
そして、端子カバー４５は、ケース本体１０に開口する端子挿通孔１５に挿入すると共に、係止フランジ部４５ｂを嵌合部１４の底部１４ａと筒型電池Ｂの端部Ｂｂとによって挟持してケース本体１０に取り付けられる。
【００７２】
一方、配線材用スリット４５ａからケース本体１０内に挿入される配線材２４の端部を端子Ｂｄに取り付けることにより、隣設する筒型電池Ｂの両端子Ｂｄ間を互いに連結し、端子カバー４５の先端を電気絶縁性のキャップ４６で覆い、かつ端子カバー４５の配線材用スリット４５ａと配線材２４との隙間は、シール部材（図示せず）で封止されている。
【００７３】
このように構成される端子カバー部材４４を装着するには、端子カバー４５を嵌合部１４から端子挿通孔１５に挿入してケース本体１０に予め取り付け、ケース本体１０の外側面１２から突出した状態で開口する配線材用スリット４５ａから配線材２４の一方の端部を端子カバー４５内に挿入すると共に、配線材２４で連結しようとする他方の筒型電池Ｂを装着すべき嵌合部１４の端子挿通孔１５にも同様に、端子カバー４５を装着し、配線材２４の他方の端部を配線材用スリット４５ａから挿入する。
【００７４】
次に、筒型電池Ｂをケース本体１０の嵌合部１４側から挿入して、筒型電池Ｂの端子Ｂｄを上記配線材２４の端部に開口する端子係止孔２４ａに挿入し、かつ係止フランジ部４５ｂを嵌合部１４の底部１４ａと筒型電池Ｂの端部Ｂｂとによって挟持してケース本体１０に取り付け、そして第１実施形態と同様に、連結軸部材２０によって両ケース本体１０及び筒型電池Ｂ等の一体化を図る。
【００７５】
続いて、配線材２４の端子係止孔２４ａから突出する端子Ｂｄにナット２５を螺合せしめて配線材２４を端子Ｂｄに取り付けることにより、隣設する筒型電池Ｂの両端子Ｂｄ間を配線材２４によって連結する。
【００７６】
そして、配線材２４に予め嵌装されたシール材を移動せしめて端子カバー４５に開口する配線材用スリット４５ａと配線材２４との間に押し込み、配線材用スリット４５ａと配線材２４との間の隙間を封止すると共に、端子カバー４５の先端をキャップ４６によって封止する。
【００７７】
従って本実施形態によると、第３実施形態に加え、係止フランジ部４５ｂを嵌合部１４の底部１４ａと筒型電池Ｂの端部Ｂｂとによって挟持して端子カバー４５をケース本体１０に取り付けることから、端子カバー部材４４の取付がより確実になる等の効果を有する。
【００７８】
以上説明した実施形態では、嵌合部をケース本体に凹設したが、筒型電池を囲むようにケース本体に筒状に突出形成することも、また円筒状の筒型電池の場合を例に説明したが、電池嵌合部の形状を変えることにより、例えば断面略矩形等他の形状の筒型電池に適用することも可能であり、本発明は上記実施形態に限定されることなく本発明の要旨を逸脱しない範囲で適宜変更可能である。
