<P>PROBLEM TO BE SOLVED: To provide a yarn winding device capable of improving the detection accuracy of a yarn failure by accurately calculating a yarn feed amount passing through a yarn failure detector. Ž<P>SOLUTION: A winding unit 10 is provided with a yarn pool section 71 for storing a yarn 20 before being wound onto a package 30, and a servomotor 55 driven for feeding the yarn 20 to the yarn pool section 71. Moreover, the winding unit 10 is provided with a clearer 15 arranged on the upstream side of the yarn pool section 71 for detecting the yarn failure, and it is configured to calculate the length of thickness unevenness that passed through the clearer 15 based on the yarn feed amount on the upstream side of the yarn pool section 71.
