PROBLEM TO BE SOLVED: To provide an apparatus for ejecting foam capable of giving fluid the foam effect with a stable state even at a very little flow volume compared with a conventional apparatus for ejecting foam.SOLUTION: The apparatus 1 for ejecting foam which ejects fluid in the foam state containing air comprises: a housing 12; an outer cylinder 14 disposed upstream of the housing 12; an inner cylinder 16 with a bottom part 16b having ejecting holes 16a for ejecting the fluid, which engages with the outer cylinder 14; an intermediate plate 15 forming an air-entraining part 17 for entraining air to the fluid, and disposed between the inner cylinder 16 and the outer cylinder 14; a first inflow opening 14a provided at the outer cylinder 14 for introducing the fluid; a second inflow opening 15a facing the first inflow opening 14a, and provided at the intermediate plate 15 communicating with the air-entraining part 17 and the inner cylinder 14; a dispersing plane 16e facing the second inflow opening 15a, and provided at the bottom part 16b; and an air suction opening 17a communicating with the air-entraining part 17, and supplying air from the outside. |
