Description
また、請求項1の発明によれば、工具箱を構成する箱体内に尿素水溶液タンクを設けることにより、工具箱の箱体によって尿素水溶液タンクを保護することができる。これにより、例えばホイール式作業車両の掘削作業時にバケットから落下した土砂や、ホイール式作業車両の走行時に車輪によって跳上げられた土砂が、尿素水溶液タンクに衝突するのを箱体によって防止することができ、尿素水溶液タンクの寿命を延ばすことができる。
また、箱体の開口を蓋体によって閉塞することにより、箱体内に配置された尿素水溶液タンクの給水口を外部から隠蔽することができるので、例えば悪戯によって尿素水溶液タンク内に尿素水溶液とは異なる異物が充填される不具合を防止することができる。さらに、尿素水溶液タンクの給水口の周囲には、箱体の内部空間によって大きな作業スペースが確保されるので、尿素水溶液タンクに対する給水作業を行うときの作業性を高めることができる。
