It is screwed (screwed) into the first inner cylinder body 2 (first inner cylinder main body 21).
In the shower head Y, as shown in FIG. 16, the shower cylinder portion 62 has a shower screw portion 65 (male screw portion) on the screw portion 34 (female screw portion) of the first distribution hole 22 (large diameter hole 31). Screw in.
The shower head Y rotates the shower body 61 in one direction (rotates in the mounting direction) with respect to the first inner cylinder body 21, so that the shower cylinder portion 62 (shower screw portion 65) is screwed on the first inner cylinder body 21. It is screwed into the portion 34 (first flow hole 22) and screwed into the first inner cylinder body 21 (first inner cylinder body 2). At this time, since the first inner cylinder body 21 (first inner cylinder body 2) cannot rotate with respect to the outer cylinder body 11 (outer cylinder body 1), the shower cylinder portion 62 is screwed (screwed). As a result, it does not rotate with respect to the outer cylinder body 11.
As the shower cylinder portion 62 is screwed (screwed), the shower body 61 attaches the seal ring 66 to the inner circumference (inner peripheral surface) of the large-diameter hole 31 of the first flow hole 22, as shown in FIG. Liquid-tightly press-contacts, and presses (presses) one shower end 61A against one first inner cylinder end 21A of the first inner cylinder main body 21 (first inner cylinder 2) to press (press) the first inner cylinder main body 21. It is attached to (first inner cylinder 2).
In the shower head Y, one shower end 61A is separated from one outer cylinder end 21A of the outer cylinder 1 (outer cylinder main body 11) by a slight gap δ, and the first one of the first inner cylinder main body 11 is separated. It is integrally attached to the first inner cylinder body 2 (first inner cylinder main body 11) by pressing (pressing) the inner cylinder end 21A.

As shown in FIG. 16, the first inner cylinder body 21 (first inner cylinder body 2) has the shower body 61 at one end of the first inner cylinder 21A as the shower cylinder portion 62 is screwed (screwed). It is attached to the shower head Y by pressing (pressing) one of the shower ends 61A.
As a result, the first inner cylinder body 21 (first inner cylinder 2) is integrally attached to the shower head Y, and the first inner cylinder main body 21 (first inner cylinder 2) and the shower head Y are integrally attached. It is made rotatable.
In the first inner cylinder main body 21 (first inner cylinder 2), the shower cylinder portion 62 of the shower head Y is provided in the first flow hole 22 (screw portion 34 of the large diameter hole 31). It is freely screwed from the end 21A.

As shown in FIG. 16, the outer cylinder main body 11 (outer cylinder body 1) has one outer cylinder end 11A and a shower main body 61 as the first inner cylinder end 21A of the first inner cylinder main body 21 is pressed. It is arranged between one shower end 61A with a slight gap σ. The slight gap σ corresponds to the protrusion amount δ (see FIG. 13) of the first inner cylinder main body 21 (first inner cylinder 2), and is, for example, 0.5 mm or less (σ = 0 or more and 0.5 mm or less). Is.
As a result, the first inner cylinder main body 21 (first inner cylinder 2) and the shower head Y (shower main body 61) do not come into contact with the outer cylinder main body 11 (outer cylinder 1) with respect to the outer cylinder 1. It becomes rotatable.
