従来、電池収納部の防水構造としては、耳かけ式補聴器の電池装置において、電池ホルダの開口部にパッキンを装着し、電池ホルダを閉じることにより電池ホルダのパッキンがケース本体の下端部に押圧され、防水シールを確保するようにしたものが知られている（例えば、特許文献１参照）。
また、挿耳形補聴器においては、電池収納部の防水構造自体が考えられていなかった。
【０００３】
【特許文献１】
実公平３−６０７６号公報（第３−４頁、第１図）
【０００４】
【発明が解決しようとする課題】
しかし、パッキンを用いた実公平３−６０７６号公報に記載の電池収納部の防水構造では、設置スペースなどの関係から挿耳形補聴器に適用できないという問題がある。
また、電池収納部の防水構造自体が考えられていなかった挿耳形補聴器においても、その使用環境から電池収納部の防水構造の必要性が叫ばれている。
【０００５】
本発明は、従来の技術が有するこのような問題点に鑑みてなされたものであり、その目的とするところは、従来の電池ホルダの操作感覚を損なうことなく、耐久性に優れた防水機能を発揮することができる電池収納部の防水構造を提供しようとするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決すべく本発明は、回動自在な電池ホルダを開状態にしてボタン形電池を電池ホルダに保持させた後に、電池ホルダを閉状態にしてにボタン形電池を収納する電池収納部の防水構造であって、前記電池ホルダが電池ホルダコアと、この電池ホルダコアを覆うと共に前記ボタン形電池をカバーして保持する弾性カバー部材から形成されたものである。
【０００７】
【発明の実施の形態】
以下に本発明の実施の形態を添付図面に基づいて説明する。ここで、図１は本発明に係る電池収納部の防水構造を適用した電池ホルダが開状態の挿耳形補聴器の斜視図、図２は挿耳形補聴器の部分断面斜視図、図３は挿耳形補聴器の横断面図、図４は挿耳形補聴器の縦断面図である。
【０００８】
本発明に係る電池収納部の防水構造を適用した挿耳形補聴器は、図１又は図２に示すように、樹脂製のシェル１とフェースプレート２でケース体３を形成し、ケース体３の内部にボタン形の空気電池４を収納する電池収納部５を設けている。更に、ケース体３の内部には、マイクロホン、補聴処理部やイヤホンなどの補聴器を構成する部品（不図示）が配設されている。
【０００９】
フェースプレート２には、電池収納部５に空気電池４を装填するための開口部６が形成され、更に図３に示すように、開口部６の縁部近傍に形成された軸部材７には、空気電池４を保持して電池収納部５に収納する電池ホルダ８が回動自在に取り付けられている。なお、図４に示す９，１０は、電池収納部５に配設された電池接片である。
【００１０】
電池ホルダ８は、図３及び図４に示すように、樹脂製の電池ホルダコア１１と、電池ホルダコア１１の表面全体を被覆すると共に空気電池４の一部をカバーして保持する弾性カバー部材１２からなる。
【００１１】
電池ホルダコア１１は、空気電池４の外周面４ａに沿って周設される壁面部１１ａと、軸部材７と係合する回動溝１１ｂと、指先を引っ掛けて電池ホルダ８を開状態にするための突起部１１ｃを備えている。
