PROBLEM TO BE SOLVED: To provide an air valve serviceable for many times in view of meeting the environmental requirements. SOLUTION: The air valve for iterative use including an air injection cock and exhaust cock for air dunnage, for example for precluding load collapse, is structured so that the injection cock of push-in type having a check valve is adhered to the exhaust cock of screw-fit type upon penetrating the center of the exhaust cock and that the injection cock and the exhaust cock are consolidated in the coupling part.
