Without any difficulty, it is possible to stably support the backrest on the front of the low tank with a large force.

Further, since this tank support supports the tank with its rear end abutting against the wall of the toilet,
In providing the tank support, there is an advantage that no installation work to the wall is required and the construction can be performed extremely easily. In this case, a hook for hooking may be provided on the tank support, and the hook may be hung from the upper end opening of the low tank to the rear wall of the tank and attached thereto. This makes it possible to attach the tank support to the low tank very easily.

[0015] The tank support may be provided with a front-rear adjustment mechanism for adjusting the front-rear length (claim 3), so that the space between the rear surface of the low tank and the wall of the toilet can be provided. Even if the interval is not constant, the rear end of the tank support can be reliably brought into contact with the wall of the toilet by the front-rear adjustment mechanism.

According to a fourth aspect of the present invention, the hook is provided with a screw fixing device for fixing the hook to the tank wall by tightening a screw.
When the hook is hooked on the tank wall, even if rattling occurs, the ratchet is used to eliminate the rattling and attach the backrest or tank support to the low tank in a firmly fixed state. Can be fixed.
