PROBLEM TO BE SOLVED: To provide a weft inserting device easy in jet direction setting operation. SOLUTION: A weft inserting auxiliary nozzle 15 is penetratedly fixed to an equilateral quadratic prism-shaped stand 19. An equilateral quadratic prism- shaped hole 163 is vertically penetrated through a support block 16 jointed to a mounting groove 131 and drawably fitted with the stand 19. The 1st joint face 21 of the support block 16 is parallel with the side faces 166, 168 of the hole 163. The angleαprovided by the 1st joint face 21 and 2nd joint face 22 is slightly smaller than 90, while the angleβprovided by the 1st joint face 21 and 3rd joint face 23 slightly larger than zero. The angleγprovided by the 1st joint face 21 and 4th joint face 24 slightly smaller than 90.
