THREAD INSERTING DEVICE FOR SEWING MACHINE

PROBLEM TO BE SOLVED: To provide a thread inserting device for a sewing machine capable of reliably holding part of a needle thread at a prescribed position near a needle hole at thread insertion. SOLUTION: Before a thread inserting shaft 17 is rotated, a second thread guide member 36 has an upper support section 37 and a connecting wall 39 on the upper side and this side of a first thread guide member 44 respectively, and a guard wall section 39b covering at least this side of the thread guide section 44a of the first thread guide member 44 is provided on the connecting wall 39 of the second thread guide member 36. When the needle thread S is hooked on the second thread guide member 36, the needle thread S is guided along the guard wall section 39b and can be reliably hooked on the first thread guide member 44 without being released from the second thread guide member 36. Part of the needle thread S can be reliably held at the prescribed position near the needle hole 14a at thread insertion, and the reliability of the thread inserting device is increased.
