  • the further relaxing effect can be acquired by applying the spout water flow W excellent in aesthetics on a bather's shoulder.
  • the storage chamber 37 is formed such that each of the pair of lower wall surface 71 and upper wall surface 73 facing the discharge passage 33 spreads away from the inlet 39 a of the throttle channel 39. Therefore, it is easier to increase the internal volume of the storage chamber 37 than when the storage chamber 37 is formed so that only one of the pair of wall surfaces 71 and 73 is separated. As a result, the water pressure of the stored water in the storage chamber 37 can be lowered and the flow rate thereof can be easily lowered, and the flow rate in the lateral width direction X can be rectified more effectively in the storage chamber 37.

  • the interval holding unit 69 is disposed in the discharge passage 33, the water flow is divided by the interval holding unit 69.
  • the interval holding unit 69 according to the present embodiment is disposed in the storage chamber 37 in which the flow rate of the water flow is slow and the distance to the discharge port 13 is farther than the throttle channel 39. Therefore, even if the water flow is divided by the interval holding unit 69, the divided water flow is likely to be merged at an early stage before reaching the discharge port 13, and the shape disturbance of the discharged water flow W due to the division of the water flow can be easily suppressed. Become.
  • the first seal member 89 can be easily detached when the split members 51 and 53 are assembled.
  • the first seal member 89 according to the present embodiment has a complicated shape that surrounds the discharge passage 33 from three sides. Therefore, if the first seal member 89 is attached to the upper divided member 53 by bonding, the assembling work is further complicated.

  • the member 53 can be assembled to the lower divided member 51, and workability at the time of assembly is improved.
  • the water discharge member 19 may be subjected to bending force that warps in the vertical direction due to screwing of the fixing member 231 (see FIG. 4), water pressure in the discharge passage 33, or the like.
  • the water discharge member 19 has a depth dimension smaller than the horizontal width dimension as shown in FIG. 5 in order to suppress the occupied space while discharging a wide discharge water flow W. Therefore, the distance from the force point to which the bending force is applied, that is, the distance from the force point to the action point tends to be longer at both ends 19a than the width direction X intermediate portion 19b of the water discharge member 19, and a larger bending moment acts accordingly. Easy to do.
  • the plurality of fixtures 81 are arranged such that the interval L2 at both ends 19a is narrower than the interval L1 at the intermediate portion 19b of the water discharging member 19.
  • the fixing degree at both end portions 19a is higher than that of the intermediate portion 19b. Therefore, while the interval L1 of the fixtures 81 is widened and the number thereof is suppressed at the intermediate portion 19b of the water discharging member 19, the interval L2 of the fixtures 81 can be narrowed at both ends 19a to effectively resist the bending moment.
  • the state where the divided members 51 and 53 are coupled can be stably maintained.
  • each divided member 51 and 53 is a resin molded product
  • the water discharging apparatus 10 of various color variations can be provided by mixing a colorant into the resin composition.
  • each of the divided members 51 and 53 is a resin molded product, post-processing such as anticorrosion treatment becomes unnecessary, and productivity is improved.
  • the water discharging apparatus 10 demonstrated the example whose base
  • the water discharge device 10 may be installed using a wash basin in a washroom or a kitchen sink as a base.
  • the installation surface 217 may be provided on the base body, and the water discharge device 10 may be installed on the installation surface 217.
  • the discharge port 13 was formed in a horizontally long slit shape, and the discharge passage 33 was formed in a horizontally long direction in the direction in which the discharge port 13 extends. These shapes are not limited to this, and may be formed in a circular shape, for example.
  • the upper divided member 53 and the lower divided member 51 have been described as examples of resin molded products, other metal cast products may be used. Even in this case, since the passage section 23 having a hollow cross section is configured by assembling a plurality of parts, the surface roughness can be easily lowered by post-processing such as cutting and polishing the inner wall surface of the discharge passage 33 by disassembling them.
  • the upper divided member 53 and the lower divided member 51 have been described as a first divided member and a second divided member having a shape obtained by dividing the water discharge member 19 in the vertical direction. In addition to these, they may have a shape divided in the width direction X. In any case, each divided member may have a shape divided in a direction intersecting with the direction from the storage chamber 37 toward the discharge port 13.
