The adjuster bottom plate member 26 is brought into contact with the upper side surface 21a. Then, the screw shaft 27 is rotated in the opposite direction without impairing the state of the packing 28 facing the raw water discharge port, so that the holding member 26a and the adjuster bottom plate member 26 are separated from the adjuster mounting portion 23a. In this case, the adjuster bottom plate member 26 is the upper side surface 2 of the faucet 21.
Since the contactor 1a is prevented from moving, the adjuster mounting portion 23a moves in a direction away from the faucet 21, and as a result, the packing 28 discharges the raw water of the faucet 21 (the lower surface 21b including the discharge port). Is pressed and adhered to. That is, the upper side surface 21a of the faucet 21 and the lower side surface 21 including the discharge port
The water purifier 22 can be fixed so as to be sandwiched with b, and the packing 28 can prevent water leakage during use.

When the water purifier 22 attached to the faucet 21 in this way is used, the operation handle 36 is operated to rotate the flow path switching valve 25 to guide the raw water to the filter cartridge 31. Cartridge 31
The adsorbent layer 33 in the interior removes odors of mustes, musty odors, organic substances, etc., and the hollow fiber bundle layer 34 removes fine impurities such as bacteria and iron rust, and flows out as purified water (filtered water) from the purified water outlet 35. To do.

When the raw water is allowed to flow out as it is, the operation handle 36 is operated to rotate the flow path switching valve 25, and the raw water can be guided to the straight water outlet 37 or the shower outlet 38 as it is. As is clear from the above description, since the water purifier 22 can be attached simply by sandwiching the faucet 21 in the vertical direction, the screw 13 which is essential when the fixture shown in FIG. 12 is adopted is unnecessary. become. As a result, even if the length of the straight pipe portion including the outlet of the faucet 21 is 10 mm or less, the water purifier 22 can be easily and surely provided.
Can be attached to the faucet 21. Further, since the water purifier 22 can be easily attached to the faucet 21 regardless of the presence or absence of the bulge and the presence of the threaded portion, the types of faucets to which the water purifier 21 can be attached can be greatly expanded. As a result, most of the various types of dedicated adapters attached to the conventional water purifier are unnecessary, and the cost of the entire water purifier including the adapter can be significantly reduced.
