The water supply device for sanitary ware according to the present invention may be installed in the sanitary ware 10 or installed in a bidet (not shown) installed in the sanitary ware 10, but in the following description, the water supply device for the sanitary ware 10 is installed as an example.

First, the water discharge hole 103 of the water supply device installed in the sanitary ware 10 is connected to each of the rim pipe 12 and the jet pipe 13, and the water supply hole 101 is connected to the tap, Water is supplied to the water supply hole 101.

At this time, the amount of water (eg, water pressure) supplied to the water supply hole 101 is checked, and when an excessive amount of water is supplied to the water supply hole 101, the motor 300 is driven to The length of the height adjustment unit 400 is adjusted.

That is, when the motor 300 connected to the rotating member 401 of the height adjusting unit 400 is driven to rotate, the rotating member 401 is rotated in place by the motor 300 and the first inclined surface 401a ) is rotated, and at this time, the second inclined surface 402a of the lifting member 402 is pushed upward and moved downward by the first inclined surface 401a, and is separated from the rotating member 401 by a predetermined distance.
