[0134] The cross-sectional area of ​​the inlet passage (331b) of the inlet portion (331) may gradually increase as the washing water flows. That is, the cross-sectional area of ​​the inlet passage (331b) of the inlet portion (331) may increase as it goes upward. Accordingly, the flow rate of the washing water may decrease as it passes through the inlet passage (331b). As the cross-sectional area of ​​the passage increases, the flow rate of the washing water decreases, and therefore, the flow rate of the washing water may decrease as it goes upward.

[0135] In this way, the flow rate at the lower portion of the inlet portion (331) where the inlet portion (331) and the protrusion portion (330) are connected can be sufficiently large. Accordingly, leakage through the gap between the connecting portions of the inlet portion (331) and the protrusion portion (330) can be minimized.
