A fire hose is provided to prevent the hose from being bent by putting a bar made of spring or a rubber stick in the fire hose. A fire hose is manufactured by putting a bar made of materials having elasticity such as a spring(202) or a rubber stick in the fire hose(201). The hose is formed so that the spring or the bar within the fire hose is fixed on both ends of the fire hose by a support rod and the spring or the bar enters a hydrant valve and prevents flow of the water for extinguishing fire. The cross-sectional area of the spring or the bar and the cross-sectional area of the fire hose are maintained at a constant ratio to maintain the constant water pressure and spray amount.
