PROBLEM TO BE SOLVED: To provide an air spinning device which can prevent that an oiling agent contained in a raw material for a spun yarn is accumulated on the outer peripheral surface of the tip portion of a hollow guide shaft. SOLUTION: This air spinning device 2 for forming a spun yarn from a fiber bundle containing an oiling agent is provided with a hollow guide shaft 22 in which a yarn passage 22d for making the spun yarn to pass therethrough is formed in the axial direction, a spinning nozzle member 21 in which a spinning chamber 21a for introducing the fiber bundle F is segmented and formed on the periphery of the tip portion of the hollow guide shaft 22, and which has nozzle holes 21b for jetting compressed air into the spinning chamber 21a to form a revolved air flow, and is used for separating fibers from the fiber bundle F traveling from the spinning chamber 21a to the yarn passage 22d and simultaneously twirling and twisting the fibers around the tip portion of the hollow guide shaft 22, and a surfactant-imparting device 24 for mixing compressed air with a surfactant for preventing that the oiling agent accumulates on the outer peripheral surface of the tip portion of the hollow guide shaft 22.
