In this tapeless stringer (1), a bottom leg portion (23) of a fastener element (20) has a first extended portion (23a) extending from a meshing head portion (21), a step portion (23b) bending from the first extended portion (23a), and a second extended portion (23c) extending from the step portion (23b), and an accommodating space portion (25) that can accommodate the material (5, 7) on which the fastener is to be attached is formed under the second extended portion (23c) by way of the step portion (23b). Thus, juddering of the fastener element (20) in an element guiding path of a slider (30) can be prevented and the sliding operation of the slider (30) can be performed easily and stably. |
