<P>PROBLEM TO BE SOLVED: To provide a cooling device for spinning multifilaments which is excellent in velocity in the circumference direction and air temperature of an air flow blown from the cooling device, and exhibits prominent effects for obtaining the filaments having good quality such as fineness, strength, elongation, or the like of the filaments. Ž<P>SOLUTION: The cooling device 5 for spinning cools and solidifies the filaments obtained by melting and spinning a polymer by blowing the air flow to the filaments from the outside of the traveling passage of the filament to the inside, and has an air flow-introducing inlet 6 having a circular flow passage arranged so as to surround the outside of the travelling passage of the filaments, a rotary disk 1 rotating in the air flow-introducing inlet by bringing the virtual central axis of a circular flow path of the air flow-introducing inlet as a virtual rotary axis, an air flow passage 4 communicating with the air flow-introducing inlet and having a circular flow path arranged so as to surround the outside of the travelling passage of the filaments in the main direction of the air flow blown by rotation of the rotary disk in the down stream of the rotary disk, and a circular straightening filter 21 arranged in the inside of the air flow passage so as to surround the outside of the travelling passage of the filaments.
