Zusammenfassung:PROBLEM TO BE SOLVED: To shorten washing time and to save water consumption in washing and rinsing work of detergent foam of washing objects.SOLUTION: A shower face 40 has a centralized water discharge hole 50 for straight discharging disposed at the center thereof and shower discharge holes 51 annularly disposed to surround the centralized water discharge hole 50. The shower discharge holes 51 are composed of small diameter holes 60 and large diameter holes 61 larger than the small diameter holes 60, at least two large diameter holes 61 are provided along the circumferential direction of the shower face 40, and the plurality of small diameter holes 60 are provided between the adjacent large diameter holes 61 along the circumferential direction of the shower face 40. The plurality of small diameter holes 60 are provided so that the water discharge amount of both sides in the circumferential direction of the shower face 40 is larger than the water discharge amount of the outer side from the large diameter holes 61 in the radial direction of the shower face 40 around the large diameter holes 61.SELECTED DRAWING: Figure 2 【課題】被洗浄物の洗剤泡の洗い流し作業において、洗浄時間の短縮と節水とを行う。【解決手段】シャワーフェイス40は、その中央部に配置されたストレート吐水用の集中吐水孔50と、集中吐水孔50を囲むように環状に配置されたシャワー吐水用のシャワー吐水孔51とを有し、シャワー吐水孔51は、細径孔60と、細径孔60よりも孔径の大きい太径孔61とから構成され、太径孔61は、シャワーフェイス40の周方向に沿って少なくとも2個設けられ、細径孔60は、シャワーフェイス40の周方向に沿って、隣り合う太径孔61の間に複数設けられ、複数の細径孔60は、太径孔61の周囲において、シャワーフェイス40の周方向両側の吐水量が、太径孔61よりもシャワーフェイス40の径方向外側の吐水量よりも多くなるように設けられている。【選択図】図2
