PROBLEM TO BE SOLVED: To provide a configuration capable of efficiently and reliably removing attached yarn wastes in a yarn monitoring device.SOLUTION: A yarn monitoring device 6 includes a holder 30, a detecting section, and a blowing section 45. The holder 30 is provided with a first yarn passage 34 for enabling passage of a spun yarn traveling along a predetermined yarn path. The detecting section is adapted to detect at least at a portion of a side wall surface 35 of the first yarn passage 34, status of the spun yarn. The blowing section 45 is adapted to blow compressed air in a predetermined blowing direction to the side wall surface 35 of the first yarn passage 34, and configured such that when viewed in a direction orthogonal to the yarn path and parallel to the side wall surface 35, the blowing direction is set diagonal to the side wall surface 35. |
