PROBLEM TO BE SOLVED: To provide a hand-washing apparatus which can fix a liquid medicine feeder in a way unable to rotate without preparing two or more screw apertures in a hand wash basin, is easily executed, and is also excellent in an outward aspect nature.SOLUTION: The hand-washing apparatus 1 has the hand wash basin 2, the liquid medicine feeder 10 fixed to the standing wall part 2a of the hand wash basin 2 through a support member 3, and an automatic spigot which emits water toward the hand wash basin 2. The support member 3 is inserted in a mounting hole 5 formed by penetrating the standing wall part 2a of the hand wash basin 2 toward the back from the front of the hand wash basin 2, a rotation stopping implement 6 is engaged with the support member 3, which projects from the back of the mounting hole 5, and the back part 2b of the hand wash basin 2 as a rotation stopping means for preventing the support member 3 from rotating in the circuit direction of the mounting hole 5, and a nut 8 is screwed on the support member 3 as a tightening means which fixes the support member 3 to the mounting hole 5. The liquid medicine feeder 10 is fixed in such a way that it cannnot rotate in the status that the protrusion 3a of the support member 3, etc. are inserted into the lock aperture 19a of the main unit 19 of the liquid medicine feeder 10.COPYRIGHT: (C)2009,JPO&INPIT【課題】手洗器に複数のネジ孔を設けることなく液剤供給器を回転不能に固定することができ、施工が容易で、外観性にも優れた手洗装置を提供する。【解決手段】手洗装置1は、手洗器2と、手洗器2の立壁部2aに支持部材3を介して固定される液剤供給器10と、手洗器2に向かって吐水する自動水栓を備えている。支持部材3は、手洗器2の立壁部2aを貫通して形成された取付孔5に手洗器2の正面から背面に向かって挿入され、支持部材3が取付孔5の周方向に回転するのを防止するための回り止め手段として取付孔5の背面から突出した支持部材3及び手洗器2の背面部2bに回り止め具6が係合され、支持部材3を取付孔5に固定する締結手段として支持部材3にナット8が螺着されている。液剤供給器10の本体部19の係止孔19a内に支持部材3の突出部3a等が挿入された状態で、当該液剤供給器10が回転不能に固定されている。【選択図】図3
