PURPOSE: An oxygen generator for truck is provided to supply oxygen using a secondary vacuum pumping part without the influence to surrounding devices when the compressed air pressure is lower than a reference value. CONSTITUTION: An oxygen generator for truck comprises an air tank(110), a vacuum ejector(30), an oxygen separating module(140), an oxygen discharge unit(150), and secondary vacuum pump(40). The compressed air is saved in the air tank. The vacuum ejector forms vacuum pressure using the compressed air which is provided from the air tank. The oxygen discharge unit is connected to the oxygen separating module and supplies the oxygen to a vehicle interior. The secondary vacuum pump offers the vacuum pressure to the oxygen separating module when the pressure of the air tank is under a reference pressure.
