(57) Disclosed is a weft insertion apparatus in which it is possible to achieve an improvement in the traveling stability of the rapier head even in a construction which adopts a guide guiding the rapier head or the rapier band only underneath the same inside the warp opening. The height position of guide position (163) in a first rapier guide (16A) outside the warp opening is set to be above the height position of guide edges (191) of second rapier guides (19) inside the warp opening. A delivery rapier head (11) linearly moves on the guide edges (191). The first rapier guide (16A) guides the widthwise end portions of a rapier band (13A), and the second rapier guides (19) guide the lower surface (204) of a reinforcing recessed frame (20) formed in the forward end portion of the rapier band (13A).
