A tee nut is integrally made of a metallic material, comprising a shaft portion and a flange portion, the latter having two pairs of pawls projecting in the direction in which the shaft portion extends, the pawls being disposed radially of the flange portion. The peripheral edge of the flange portion is formed with projections at positions opposed to each other in a radial direction which is at right angels with the radial direction in which the two pairs of pawls are opposed to each other, the projections extending in the same direction as that in which the pawls extend. The clearances in guide rails of C-shaped cross-section constituting a feed track are substantially decreased in size by the presence of the pointed projections producing a decreased frictional resistance, and the overlapping of the flange portions due to the rise of the flange portions in the guide rails is prevented, thus ensuring smooth movement of the tee nut along the feed track.
