<p>[PROBLEMS] To provide a slider capable of preventing it from falling off a chuck, a chuck base part from being damaged, and a damaged portion from being elongated or cut off even when contents are filled in a bag body excessively beyond its content volume and the slider and the chuck are forcibly closed to close the chuck. [MEANS FOR SOLVING PROBLEMS] This slider (S) comprises a pair of falling prevention projections (S5). The falling prevention projections are formed on an outer guide (S6) projectedly inward between an opening end (SOE) and a closing end (SCE) and, in the installed state of the slider across the top edges of the chuck, the chuck is held from the lower outside of the chuck. The outer guide of the slider comprises a pair of falling prevention auxiliary projections (AS) for limiting the degree of opening of the chuck near the opening end of the slider.</p> |
