There are various forms such as normal shower sprinkling, foam shower sprinkling, massage shower sprinkling, and concentrated sprinkling. As the shower head, there is a single-function shower head capable of spraying water in only one of the above-described water discharge modes, and a multi-function shower head capable of discharging water by switching to three or more modes. By the way, compared with a single-function showerhead, a multifunctional showerhead has a complicated internal structure and a large number of parts, and tends to increase in size (see Japanese Patent Laid-Open No. 63-270563).

[0003]

However, such an increase in the size of the shower head causes a problem when it is used in a kitchen, a washroom, etc., resulting in poor workability. However, since the small shower head has only a single function and at most two functions, there is a problem that the shower head has to be replaced if the user wants to use other functions, which is costly. .
