PROBLEM TO BE SOLVED: To provide a foam head capable of imparting directionality in the radial direction with a simple constitution. SOLUTION: This foam head has a head body 1 having a liquid feeding passage for passing a fire extinguishing liquid, a wire net 13 installed under the head body, and a deflector 17 arranged inside the wire net. The fire extinguishing liquid is injected from a nozzle hole arranged in the liquid feeding passage, and is radiated by colliding with an upper surface of the deflector 17. In this foam head, an upper wall 21 is arranged on the upper surface side of the deflector, and bending parts 21a and 21b bent in the radial direction of the fire extinguishing liquid, are arranged in both end parts of the upper wall. The center of the nozzle hole is arranged by being dislocated from the center of the liquid feeding passage 5. COPYRIGHT: (C)2005,JPO&NCIPI
