PROBLEM TO BE SOLVED: To provide a spray head which can simply connect each spray element or a junction component in the shape of an assembly kit without needing the fixing of constitution components to each other by using a screw bolt etc. SOLUTION: In order to connect spray crosspieces to each other, a cylinder bolt-shaped binding element 25 having a through-hole 32 is set. The binding element has a recession having inclined surfaces 27 and 28. The conical end part of a hollow screw 30 is engaged with the recession so that the binding anchoring action of the adjoining spray frame crosspieces is produced. The binding element 25 has seal rings 26 at both end parts, and the hole of the seal ring matches the through passages 17 and 19 of the spray crosspiece. COPYRIGHT: (C)2005,JPO&NCIPI
