Abstract
【解決手段】コイルユニットは、蓄電装置5のケースに取り付けられる取付面77を有する樹脂製のケース30(アッパーカバー32)と、ケース30内に設けられた金属板35と、金属板35に対して取付面77と反対側に位置するコイル16と、金属板35とケース30(アッパーカバー32)との間に位置する空間部36を取り囲むように配置される金属部材80とを備える。金属部材80は、樹脂製のアッパーカバー32と一体成形されている。
【選択図】図5
Description
上述の実施の形態においては、格納ケース70に隣接する第4金属部材84が切り欠き部85を隔てて2つに分割されている例を示した(図4参照)。しかしながら、第4金属部材84の構成は必ずしもこれに限定されるものではない。
上述の実施の形態においては、コイル16の横に配置される格納ケース70が、金属部材80とは別に設けられる例を示した(図4参照)。しかしながら、格納ケース70が金属部材80とともにアッパーカバー32と一体成形されるようにしてもよい。
上述の実施の形態においては、金属部材80は、金属板35側および取付面77側の双方においてアッパーカバー32から露出している例を示した(図5,図6参照)。しかしながら、金属部材80の構成はこれに限定されるものではない。
