An air pressure source supplying device for a moving cart system is provided to remove lateral pressure to a trolley by supplying compressed air to an air receiving device by using pressure of compressed air. An air pressure source supplying device for a moving cart system comprises an air supply cylinder(20), a first air supply body(30), a second air supply body(40), a first valve unit(50), a second valve unit(70), and a third valve unit(90). The first air supply body had a hollow part(33) and connects with the air supply cylinder. The second air supply body has a communication unit connected with the hollow part and connects with the first air supply body. The second air supply body inserts in a socket of an air receiving plate and has an airtight holding unit(49). The airtight holding unit is deformed by air pressure. The first valve unit is installed outside of the hollow part of the first air supply body. The first valve unit connects the hollow part with the communication unit selectively through a first spool(51) which is supported by a first spring(52). The second valve unit is installed inside the hollow part of the first air supply body. The second valve unit connects the hollow part with the communication unit selectively through a second spool(73) which is supported by a second spring(74). The third valve unit is installed inside the communication unit of the second air supply body, and connects an air receiving device with the communication unit selectively through a third spool(91) supported by a third spring.
