a slider body in which upper and lower blades are connected at front ends thereof to each other by a connecting post and a Y-shaped element guide passage is arranged between the upper and lower blades to extend from shoulder mouths located at a side of the connecting post to a rear mouth located at a side opposite to the connecting post; a pull tab having a body for operating the slider body, a pair of arm portions provided to extend from one end of the body and a connection rod connecting the pair of the arm portions; and a locking pawl arranged on the upper blade and having a pawl portion at one end thereof and a cover portion provided between the one end and the other end to cover at least a part of the connection rod of the pull tab, wherein the pull tab is pivotally held on the upper blade at the connecting rod thereof, wherein the locking pawl is fixed on the slider body at the other end thereof, wherein the pull tab has a rotatable region including laid-down positions where the pull tab is laid down toward the shoulder mouths and rear mouth of the slider body, and a stood-up position where the pull tab is stood up from the laid-down positions by pivotal operation of the connection rod, wherein, within the rotatable region of the pull tab, the locking pawl is elastically deformed to move the cover portion, and the pawl portion is arranged to be inserted into and removed from the element guide passage in accordance with movement of the cover portion, and wherein when the pull tab is completely laid down toward the shoulder mouths and rear mouth relative to the slider body, the pull tab has respective regions in which the pull tab is rotatable over a predetermined angle without exerting any load on the locking pawl. |
