PURPOSE: An air conveyer is provided to prevent air loss by moving in a desired direction with air discharged through an air discharge port where article are carried without an additional control device. CONSTITUTION: An article is placed on a ball(3) and a spring(2) established with elasticity to be expanded by weight of article is contracted to come into inside of a body(6). The ball is directed downward to open an air injection port(5) and air inside the body is injected into the air injection port(5). A light weight article moves in state of slightly floating leftward. The ball is determined with position by a seat(4) to rise in a stable state. Then the article passes by and the ball upward of the spring returns to close off the air injection port to prepare for next operation. Load of article is uniformly distributed in the ball with plural loads of article and a protrusion portion is formed between plural bodies(6) for active transfer. In initial operation, load of article is distributed and air is injected into the air injection port so the article is easily moved.
