Abstract

A deflective inflow portion 18 is formed at the forward end of a flow passage forming portion 141 of a thread guide 14. The deflective inflow portion 18 is formed by cutting the forward end portion of the flow passage forming portion 141 along a plane S obliquely intersecting the center axis line L of a weft passage 143. When forming the deflective inflow portion S by cutting along the plane S, the cutting is effected from the outlet 144 of the weft passage 143 toward the inlet 145 of the weft passage 143. The deflective inflow portion 18 is entirely surrounded by an air flow passage 16.
