PROBLEM TO BE SOLVED: To provide a needle thread feeding device for a sewing machine, which can reliably prevent the occurrence of kinks in a needle thread by using a simple configuration.SOLUTION: A spool 33 is supported on a support base 22 so as to be rotated as a needle thread 13 is fed by the driving of a sewing machine 10. The support base 22 is rotated by a motor 23 in a direction opposite to the feeding direction of the needle thread 13 from the spool 33, and thereby the needle thread 13 excessively fed from the spool 33 is rewound onto the spool 33. By using a simple configuration comprising the support base 22 and the motor 23, the occurrence of kinks in the needle thread 13 can be reliably prevented. |
