A seesaw style air pump is provided to perform injecting or discharging of the air with small force since the air is sucked or exhausted by either both hands or both feet as well as by cooperation of two people. A seesaw style air pump operates suction and exhaust simultaneously and continuously. An intake passage(40) is formed at a suction port(41) to introduce the air. An exhaustion passage(30) is formed at an exhaust port(31) to discharge the air. A pair of check valves(12,22) for intake is connected to both sides of an intake passage so as to open for only intake. A pair of check valves for exhaust(11,21) is connected to both sides of the exhaust passage so as to open only for exhaust. The air pump is connected through a pair of the intake check valve and the exhaust check valve. A main chamber is formed of materials contracted and expanded as the air is exhausted and sucked in accordance with opening/closing of the intake and exhaust check valves.
