On the other hand, a side surface facing the yarn feeding roller of a support portion provided to sandwich the yarn feeding roller from the axial direction;
On the side of the yarn feed roller opposite to that side,
A support structure for a yarn feeding roller, characterized in that magnets are provided so that opposing surfaces have the same polarity, and the yarn feeding roller is supported in the axial direction by the repulsive force of the magnets. (2) An air hole for sending air toward the inner circumferential surface of the thread feeding roller is provided on the outer peripheral surface of the shaft that supports the thread feeding roller to support the thread feeding roller in the radial direction. A magnet is attached to a side surface of the support section provided to sandwich the yarn feed roller from the axial direction, which faces the yarn feed roller, and a side surface of the yarn feed roller, which is opposite to that side surface, so that the opposing surfaces have the same polarity. A support structure for a yarn feeding roller, characterized in that the yarn feeding roller is supported in the axial direction by the repulsive force of the magnet.
