  Thus, in a state where the operation region of the operation unit 10 is in the operation region for adjusting the water discharge amount, the water discharge amount can be increased according to the rotation amount by rotating the operation unit 10 in the direction of the right screw.

  Moreover, when the area of the clearance gap formed between the valve body 6a and the valve seat 4a becomes larger than the opening area of the valve seat 4a as a result of rotating the operation part 10 to the right-handed direction, it is discharged from the spout 2. Since the amount of water discharged depends on the opening area of the valve seat 4a, the water discharged from the water discharge port 2 as shown in FIG. The amount of water discharged does not change.

  As described above, when the operation area of the operation unit 10 is in the water discharge confirmation operation area, only the minimum water discharge amount can be discharged from the water discharge port 2, so that the user cleans the face and hands. Is not suitable. However, by further rotating the operation unit 10 in the direction of the right screw, the operation region of the operation unit 10 is changed from the operation region for checking water discharge to the operation region for adjusting the water discharge amount, and the user cleans the face and hands. It becomes possible to discharge water of a water discharge amount suitable for performing from the water discharge port 2.
