Abstract: PROBLEM TO BE SOLVED: To provide an air exhaust valve having large vacuum destruction ability and capable of vacuum-destructing quickly. SOLUTION: A valve chamber 3 in which an inlet port 4 is opened in its lower part and an outlet port 5 is opened in its upper part is formed by a casing consisting of a main body 1 and a lid 2. A valve seat 6 is formed between the valve chamber 3 and the outlet port 5. The main body 1 has a plurality of ribs 9 protruding on an inner side on an inner wall of the valve chamber 3 integrally, and a float receiver 10 which has substantially bottomed cylindrical shape and a through hole 11 having a small opening area in its bottom part is fixed on an inner side of the rib 19 by a snap ring. A spherical float 12 is arranged in the float receiver 10 in a free condition. The lid 12 has a barrier member 13 in which a plurality of ribs 14 are provided on an inner wall of the outlet port 5 integrally. The barrier member 13 is positioned in substantially central part of the outlet port 5. Since direct advance of external air into the central part of the valve chamber is prevented by the barrier member 13, its speed is reduced, and it flows into the valve chamber 3 at a low speed, it scarcely hits the bottom part of the float receiver 10 and rebounds, and it becomes difficult for pressure below the float 12 in the float receiver 10 to rise. For this reason, the float 12 does not float up easily.
