Since it is not fixed only by the rubber cushion material 36, the vibration of the cistern tank 11 is absorbed. And since the back of the water tank tray 34 is not fixed on the cistern base 31 via the anti-vibration rubber 35, it further absorbs vibrations and performs anti-vibration and sound insulation.

As described above, only one direction of the side surfaces of the cistern tank 11 and the water tank tray 34 is screwed and the other direction absorbs vibrations twice by the anti-vibration rubber 35 and the cushioning material 36. The generated vibration and noise can be further reduced.
Further, since the anti-vibration rubber 35 is provided in only two places, that is, the rear left and right ends of the water tank tray 34 having a large width, the cost can be suppressed and effective anti-vibration can be performed.
