PROBLEM TO BE SOLVED: To provide a water battery attachment which assists pouring liquid into a water battery.SOLUTION: This water battery attachment comprises a battery accommodate casing body with an accommodate opening and a liquid injector for pouring a liquid into an inlet of a water battery accommodated in the battery accommodate casing body. The liquid injector includes a water storage part and a tube part. The water storage part is provided with a liquid inlet port larger than the inlet port of the water battery, which can be closely fit in the battery accommodate casing body. The tube part is provided with a flow passage connected to the water storage part and also provided with a discharge port for discharging the liquid through the flow passage, which is smaller in diameter than the inlet port of the water battery. Regarding the water injector, when the water storage part is fit in the battery accommodate casing body, the positions of the tube part and the inlet port of the water battery are aligned almost concentrically, with the discharge port being fit into the water battery via the inlet of the water battery.COPYRIGHT: (C)2012,JPO&INPIT【課題】水電池に液体を注入する注入作業を補助する水電池アタッチメントを提供すること。【解決手段】水電池アタッチメントは、収容口が形成された電池収容ケース本体と、電池収容ケース本体に収容された水電池の注入口に液体を注入するための液体注入具とを有する。液体注入具は、貯水部と管状部を有する。貯水部は、水電池の注入口よりも大きい液体注入口を備えており、電池収容ケース本体に嵌る形状を有する。管状部は、貯水部内と連なって通じる流体路と、該流体路内の液体を排出する排出口を備えており、外径が水電池の注入口よりも細い。液体注入具は、貯水部を電池収容ケース本体に嵌めたとき、水電池の注入口と管状部の位置がほぼ同軸に決まり、排出口が該水電池の注入口を通じて該水電池内に収まる。【選択図】図4
