Further, in the water spouting part 4 of the faucet 2 of this embodiment, the first flow path forming part 50 is configured integrally with the connecting part 18, and the second flow path forming part 52 is configured integrally with the first flow path forming part 50 and the connecting part. It is constructed separately from 18. According to such a configuration, manufacturing costs can be reduced by integrally configuring the first flow path forming part 50 and the connecting part 18, and the second flow path forming part 52 can be integrated with the first flow path forming part 52. By configuring it separately from 50, the degree of freedom in designing each flow path is improved.

Further, the water spouting part 4 of the faucet 2 of this embodiment further includes a screw 72 as a fixing member, and the screw 72 is configured to fix the second flow path forming part 52 to the first flow path forming part 50. It passes through the second flow path forming section 52 and is inserted into the first flow path forming section 50 . According to such a configuration, the second flow path forming part 52 can be fixed to the first flow path forming part 50 with the screw 72. Further, when a sealing packing is provided in the flow path forming portions 50 and 52, an action of pressing the packing toward the first flow path forming portion 50 can be generated.

Further, the faucet 2 of this embodiment includes the water spouting part 4 as the water spouting part structure described above. According to such a configuration, the same effects as the water spouting section 4 can be achieved.

Note that the present invention is not limited to the above embodiments, and can be implemented in various other ways. For example, in the embodiment described above, a case has been described in which the air outlet 24 and the individual air flow path 60 are provided at three separate locations at intervals in the circumferential direction R, but the present invention is not limited to such a case. If the air outlet 24 and the individual air passages 60 are provided in at least two separate locations with an interval in the circumferential direction R, the second water discharge passage 34 for straight water discharge can be arranged in the gap between the individual air passages 60. can be placed so that it passes through. Alternatively, even if only one air outlet 24 and one individual air flow path 60 are provided, by forming a shape partially chipped in the circumferential direction R, the second water discharge flow path 34 can be formed in the chipped portion. can be placed so that it passes through.

Although the invention has been fully described with reference to preferred embodiments and with reference to the accompanying drawings, various variations and modifications will become apparent to those skilled in the art. It is to be understood that such variations and modifications are included insofar as they do not depart from the scope of the invention as defined by the appended claims. Further, combinations and changes in the order of elements in the embodiments can be realized without departing from the scope and spirit of the present invention.

The present invention is useful for faucets used in kitchens, washrooms, baths, and the like.
