PROBLEM TO BE SOLVED: To provide a spinning apparatus, with which in the production of a synthetic fiber yarn, end breakages in a yarn production process can be prevented and a yarn having a slight fineness unevenness (U%) can be obtained. SOLUTION: A cooling air flow 15a controlled in temperature is introduced from an inlet 34 of an external frame 30 into the external frame 30 and the introduced cooling air flow 15a is further sent through a vent hole 35a of a cylindrical body 35 to a cooling flow supply chamber 38. Then, the cooling air flow 15a is passed through a cylindrical filter 31 to give a straightened cooling air flow 15 and the cooling air flow 15 is uniformly blown out on the circumferences of single yarns 7 in a manner of crossing the yarns 7 from the inner peripheral surface of the cylindrical filter 31 to cool the single yarns 7.
