Provided is a device for polishing a slide fastener element, the polishing device being capable of high-efficiency polishing with the fastener element in a stable orientation, and without reducing the quality of the polished product.
This polishing device is provided with: a transport path for the slide fastener (S); a support part (3, 3a, 13) disposed along the transport path and disposed opposite either the rear surface or the front surface of a fastener element (E) so as to support the orientation of the fastener element (E); and a polishing part (2, 2a, 2b) on either side of the transport path, disposed opposing the support part (3, 3a, 13). The polishing part (2, 2a, 2b) has a rotation shaft (22) and a polishing member (25) secured to the rotation shaft (22) and capable of rotating by means of the rotation of the rotation shaft. The polishing member (25) contacts and polishes either the front surface or the back surface of the fastener element (E). The rotation shaft (22) of the polishing member (25) extends parallel to the direction perpendicular to the support part (3, 3a, 13).
