Further, at the central portion of the annular support groove 71, a communication port 72 communicating the central hollow portion 54a of the center pipe 54 with the inside of the upper case 42 is formed.
　ここで、本実施形態では、ロワーケース４１の側壁（カートリッジケースの側壁）４１ｄの内面と筒状側壁５３の外面との間に、流入口２から流入した原水が下方から上方に向けて流れ、当該原水をメッシュ５５を介して筒状側壁５３に供給する原水通路（水通路）１０が設けられている。そして、原水通路１０の原水通過方向（水通過方向：図１中上下方向）の途中に、ロワーケース４１の側壁４１ｄの内面から筒状側壁５３に向けて所定量突出し、原水の流れを分散させて積極的に浄化材収納容器５２の筒状側壁５３方向に原水を案内するガイド突起（リブ）１１が設けられている。 Here, in the present embodiment, the raw water flowing from the inflow port 2 flows upward from below between the inner surface of the side wall 41 d of the lower case 41 (the side wall of the cartridge case) and the outer surface of the cylindrical side wall 53 A raw water passage (water passage) 10 for supplying the raw water to the cylindrical side wall 53 via the mesh 55 is provided. Then, in the middle of the raw water passage direction of the raw water passage 10 (water passing direction: the vertical direction in FIG. 1), a predetermined amount protrudes from the inner surface of the side wall 41 d of the lower case 41 toward the cylindrical side wall 53 to disperse the flow of raw water A guide protrusion (rib) 11 is provided to actively guide the raw water in the direction of the cylindrical side wall 53 of the purification material storage container 52.
　本実施形態では、原水通路１０がメッシュ５５の外周に同心円状に設けられるとともに、ガイド突起１１がロワーケース４１の内周に沿って連続した環状リブとして突設されている。このとき、ガイド突起１１の内周とメッシュ５５との間には、原水通路１０を流れる原水をガイド突起１１の上流側で浄化材収納容器５２に流入する原水と下流側で当該浄化材収納容器５２に流入する原水とに振り分ける隙間δが設けられている。さらに、本実施形態では、ガイド突起１１の上流側で浄化材収納容器５２に流入する原水の量と下流側で浄化材収納容器５２に流入する原水の量とが略等しくなるように隙間δを設定している。 In the present embodiment, the raw water passage 10 is provided concentrically on the outer periphery of the mesh 55, and the guide projection 11 is provided as a continuous annular rib protruding along the inner periphery of the lower case 41. At this time, between the inner periphery of the guide projection 11 and the mesh 55, the raw water flowing through the raw water passage 10 flows into the purification material storage container 52 on the upstream side of the guide projection 11 and the purification material storage container on the downstream side A clearance δ is provided to distribute the raw water flowing into 52.

And the raw water which flowed in from the inflow port 2 passes through the opening part 22, is distributed in the direction along the end plate 51 of the purification material storage container 52, and flows in the raw water passage. Therefore, the distribution path of the raw water from the inlet 2 to the raw water passage 10 is a bending path 12 which is bent over the cylindrical side wall 53 of the purification material storage container 52 for taking the raw water from the end plate 51 of the purification material storage container 52. And communicate with the raw water passage 10. Further, a seat 23 protrudes from the upper surface of the cover 21 of the inflow port 2, and the center portion of the end plate 51 is supported by the seat 23.

Then, water from which residual chlorine and the like have been removed passes through the center pipe 54 and is supplied to the central cavity 54a, and the filtered water in the central cavity 54a passes through the communication port 72 of the intermediate plate 7 via the non-woven fabric. After flowing into the inside 42 and removing fine dirt and turbidity by the hollow fiber membrane 6 housed in the upper case 42, the hollow fiber membrane 6 flows out from the outlet 3 as clean water.
