PROBLEM TO BE SOLVED: To provide a pneumatic flute in a spinning machine easy in production and capable of being produced without using a large size forming apparatus. SOLUTION: This pneumatic flute 1 is composed of four divided pieces 2a to 2d together constituting a flute part 2, an inhalation tube 3 integrated with the divided piece 2b and end plugs 4 engaged with the divided pieces 2a and 2d. The divided pieces 2a to 2d and the inhalation tube 3 are made of a synthetic resin, and each divided piece has two inhalation holes 10. The divided pieces 2a and 2d, arranged at both ends respectively, are formed in an identical shape to each other, and engaging parts 11 are formed in a swelling manner to have a larger diameter by the wall thickness at the both ends corresponding to the adjacent divided pieces 2b and 2c. The divided piece 2b has the inhalation tube 3 in a protruding manner from the center and formed with a uniform diameter, covering all the longitudinal length. The divided piece 2c has an engaging part 11 at the end corresponding to the divided piece 2b. Each divided piece 2a to 2d is connected to each other through adhesive applied on the engaging surfaces of engaging parts 11.
