A valve box 3 having a vent hole 1 formed in the upper part and a fluid inlet port 2 formed in the lower part, a floating valve body 4 for opening and closing the vent hole 1, and a valve box. The air valve is equipped with a float 5 that pushes up the floating valve body 4 to close the valve body 4 as the internal water level rises, and when the internal water of the valve box 3 is completely frozen, the volumetric expansion of the internal water causes compressive elasticity. An air valve in which the float 5 is provided with an elastic part (11 or 12) that is deformed and absorbs the volumetric expansion of the internal water. 2. The floating valve body 4 is provided with a vent hole 8 having a smaller diameter than the vent hole 1 of the valve box 3 in a state that is closed by contact with the upper surface 5a of the float 5, and the upper surface 5a is provided with an elastic part ( 11. The air valve according to claim 1, wherein the air valve is made harder than 11 or 12).
