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.
