By making the figure 36 an elongated line, it is possible to make the figure 36 more easily visible to the user than a point like the figure 35. Further, by making the figure 36 a line extending in the width direction, each figure 36 can be more reliably hidden according to the push position of the push button 33.

In FIGS. 5A to 5C, the first symbol 20a, the second symbol 20b, and the third symbol 20c are displayed in this order from the right when viewed in the push direction A1, but in FIGS. 7A to 7C, the symbol 20a is displayed. , 20b, 20c are arranged in a different order. Specifically, in FIGS. 7A to 7C, the first symbol 20a, the second symbol 20b, and the third symbol 20c are displayed in this order from the left, not from the right, when viewed in the push direction A1. Corresponding to the order of the first symbol 20a to the third symbol 20c, the first display 24a to the third display b24c of the corresponding display unit 24 are also displayed in order from the left.

In FIGS. 7A to 7C, the display indicating the state where the protrusion level is the highest (the first symbol 20a and the first display 24a) is arranged on the leftmost side, and as the protrusion level becomes smaller, the display indicating the protrusion level is displayed. Placed on the right side. As a result, each time the push button 33 is pressed, the display indicating the protrusion level can be changed from left to right. Therefore, the water discharge form can be recognized more intuitively than when the display indicating the protrusion level shifts from right to left.

Further, the water discharge form is assumed to be three forms, but the water discharge form is not limited to this. The water discharge form may be, for example, two forms, or four or more forms. In this case, the same number of protruding positions of the push buttons 30 may be provided according to the number of water discharge forms.

Further, although the plurality of figures 34 have the same shape, they may be different figures from each other.

Further, from the position where the push button 30 is most projected from the spout body 10 (P1) to the position where the push button 30 is pushed most toward the spout body 10 (P3), each time the push button 30 is pressed, the figure 34 is reduced by one. I tried to do it, but it is not limited to this. For example, each time the push button 30 is pressed, the number of figures 34 may be reduced by a plurality. Further, for example, at least a part of the region exposed from the spout body portion 10 at the first push position P1 may be covered by the spout body portion 10 at the second push position P2.

Further, although the symbol includes a figure or the like imitating the water discharge form, the symbol may include characters.
