In a Y bar for forming coupling elements, an opening angle (θ) of a pair of right and left leg parts (13) is narrower than that of the ordinary one. Plural bent portions (13a to 13c, 14a), which are bent inward, are formed successively in an extending direction of the leg parts (13) in a range from a crotch part (12) toward pawl parts (14) at front ends of the leg parts (13). The gap between the pawl parts (14) are narrowed gradually from proximal ends to front ends thereof. Bulging portions (12a) are provided on outer side surfaces of the crotch part (12). Thus, the stabilization of the posture of a metallic coupling element, which is obtained by cutting the Y bar (10), at the time of mounting, strength of the coupling element and stabilization of the mounting posture of the coupling element to the fastener tape can be improved. <IMAGE> |
