The width dimension (in the figure, the arrow Y in the figure) from the middle part (the part where the insertion part 64 is provided) in the length direction (the direction indicated by the arrow X in the figure) toward both ends (the left and right ends in the figure) The dimension of the direction shown is gradually reduced, and is provided close to the inner side of the water spray plate body 61 in the width direction. That is, the plurality of water spray holes 63 are arranged in a tapered shape toward both ends in the length direction of the water spray plate main body 61, and are provided in a large number in the middle portion in the length direction of the water spray plate main body 61, and gradually toward the both ends. Are provided so that the number decreases.

  In addition, as shown in FIG. 12, in the state where the watering plate 31C is held by the holding member 31B, the watering plate body 61 is curved in an arch shape along the curved portion 55 of the holding member 31B, and a plurality of watering projections are formed. 62 are respectively inserted into the holding holes 56 of the holding member 31B, and the watering direction of each watering hole 63 in the plurality of watering holes 63 is outward in the width direction from the inner side to the outer side in the width direction in the region A. Is directed. That is, the water spray plate 31 </ b> C is held by the holding member 31 </ b> B so that the water spray direction of the water spray holes 63 positioned on the outer side in the width direction of the water spray plate main body 61 is directed outward from the inner water spray holes 63. The watering direction of the watering hole 63 is directed in a direction orthogonal to the surface of the curved portion 55 of the holding member 31B. When the surface of the curved portion 55 is curved in an arc shape, a circle including the arc is included. The watering direction will be directed in the radial direction.

  The overhead shower unit 14 including the watering plate 31C having the plurality of watering holes 63 as described above and the holding member 31B that holds the watering plate 31C so as to sprinkle hot water in the watering range shown in FIG. It is configured. Here, FIG. 14 (A) is a schematic plan view of the overhead shower unit 14 as viewed from below, and FIG. 14 (B) is a side view showing a state of sprinkling hot water from the overhead shower unit 14. 14 (C) is a plan view showing a sprinkling range A ′ of hot water at a predetermined height H by the overhead shower portion 14.

  The predetermined height H is, for example, the height of the user's shoulder, and a desired watering range A ′ can be obtained at this height position. That is, as described above, the water spray holes 63 are arranged in the region A that is tapered toward both ends in the length direction of the water spray plate main body 61, and the water spray holes in the region A from the inner side to the outer side in the width direction. The water spray direction of 63 is provided outward in the width direction, so that when the hot water W sprinkled from each water spray hole 63 reaches a predetermined height H, the inside of the substantially circular water spray range A ′. Are distributed evenly.

  In addition, as shown in FIGS. 13 and 14, the shape of the region A in which the water spray holes 63 are arranged is such that the number of water spray holes 63 gradually decreases toward both ends in the length direction of the water spray plate body 61. It may be set as shown in FIGS.

  The shape of the region A shown in FIG. 15 is provided close to the inner side in the width direction of the water spray plate body 61 while the width dimension gradually decreases from the middle portion in the length direction of the water spray plate body 61 toward both ends. The width dimension of the region A is provided to decrease from the intermediate portion in the length direction of the water spray plate body 61 toward both end portions at a constant rate. Specifically, in the middle part of the water spray plate body 61 in the length direction, a maximum of nine water spray holes 63 are arranged in the width direction of the water spray plate body 61, and eight adjacent to the end side of this row. As the water spray holes 63 are arranged, the number of water spray holes 63 decreases by one toward the end in the length direction of the water spray plate main body 61, and the number of water spray holes 63 is three at the extreme end of the region A. It is decreasing until. The shape of the region A in which the sprinkling holes 63 are arranged in this way is an octagon extended in the length direction of the sprinkling plate body 61, and the hot water W sprinkled from each sprinkling hole 63 is substantially circular. The length and width inscribed in the sprinkling range A ′ are dispersed in an octagon that is substantially equal to reach the predetermined height H.

  The shape of the region A shown in FIG. 16 is provided close to the inner side in the width direction of the water spray plate main body 61 while the width dimension gradually decreases from the middle portion in the length direction of the water spray plate main body 61 toward both ends. In the area A, the water spray holes 63 are arranged relatively randomly. That is, the watering holes 63 are provided so as not to be regularly arranged in either the length direction or the width direction of the watering plate body 61. The hot water W sprinkled from the water sprinkling holes 63 arranged in this manner is randomly distributed even in the substantially circular water sprinkling range A ′ and reaches the predetermined height H, so that the user can change the direction. A natural watering feeling can be obtained without being conscious of sex.

  The shape of the area A shown in FIG. 17 is provided close to the inner side in the width direction of the water spray plate main body 61 while the width dimension gradually decreases from the middle portion in the length direction of the water spray plate main body 61 toward both ends. In the region A, watering holes 63 are provided side by side in a direction inclined in both the length direction and the width direction of the watering plate body 61. The hot water W sprinkled from the water sprinkling holes 63 arranged in this way reaches a predetermined height H with widening in the width direction so that the directionality of the arrangement is eliminated in the substantially circular watering range A ′. As a result, the user can get a natural feeling of watering without being aware of the direction.

  As described above, the shape of the region A in which the water spray holes 63 are arranged is formed such that the width dimension gradually decreases from the middle portion in the length direction of the water spray plate body 61 that is the water spray surface toward both ends. As shown in FIGS. 13 and 14, the width dimension gradually decreases as shown in FIGS. 13 and 14, in which the number of water spray holes 63 decreases stepwise, and as shown in FIG. 15, the number of water spray holes 63 increases at a constant rate. As shown in FIG. 16, the number of sprinkling holes 63 decreases at an irregular rate as shown in FIG. 16, or as shown in FIG. 17, one is a constant rate and the other is an irregular rate. Any of those in which the number of 63 is reduced may be used. That is, although the form in which the width dimension of the region A gradually decreases is not particularly limited, as shown in FIG. 13, the length dimension L of the portion is larger than the width dimension W on the intermediate portion side in the gradually decreasing portion. The average gradually decreasing rate of the width dimension W with respect to L is preferably less than 1 (W / L <1), and further the gradually decreasing rate is 1/2 or less (W / L ≦ 1/2). Is more preferable.

  According to this embodiment, there are the following effects. That is, the width dimension of the region A where the water spray holes 63 are formed is larger than both ends in the length direction of the water spray plate main body 61, and on the intermediate side of the water spray plate main body 61 where the number of water spray holes 63 is large, the width direction outer side. By spraying the watering direction of the watering hole 63 located at the outer side in the width direction, water can be sprayed over a wide range. On the other hand, at the both ends in the length direction of the water spray plate main body 61 having a small width dimension in the region A, the shape of the water spray range A ′ can be made close to a circle by spraying water so that it does not spread so much in the width direction.

  In this way, in the water spray plate 31C, the arrangement of the plurality of water spray holes 63 is appropriately set, and the water spray direction of each water spray hole 63 is set by the holding member 31B, so that the outer shape of the water discharge member 31 or the overhead shower unit 14 is obtained.
