Abstract

In a upper stopper device for a slide fastener having a cross section of a substantially U shape, which is adapted to be attached continuously to a fastener element row of a stringer capable of being engaged with or separated from each other, an end portion of the upper stopper device opposite to the fastener element row is formed with a widened portion, which abuts against wing plates at a shoulder opening of a slider into which the stringer is inserted so that the slider can stop. Further, a caulking portion is formed in a range between the widened portion and at an end portion side toward the fastener element row. The slider abuts against the widened portion of the upper stopper device attached to the stringer so that it reliably stops.
