Abstract:
1. A slide fastener with a separable bottom end stop, comprising: a slider that passes through first and second element rows each including coil- or zigzag-shaped continuous fastener elements fixed to opposing tape side edge portions of a pair of left and right fastener tapes; an insert member fixed to an end of the first element row; and a pivot support member fixed to an end of the second element row, wherein the insert member includes an insert plate portion of a thin plate form that is fixed to front and back tape surfaces of one of the fastener tapes and has first and second surfaces, and a pivot shaft portion disposed to protrude on an end portion of the insert plate portion at a side opposite to the first element row, the pivot support member includes first and second surfaces and includes a box pin portion that extends from an end of the second element row to a tape end portion side in a tape length direction and holds the slider and a box portion that extends from the box pin portion through a first step portion, the box portion having a nearly J shape that allows the pivot shaft portion to be engageable and disengageable with a J-shaped inner wall surface from a side of the pivot support member and to be engageable and disengageable with the J-shaped inner wall surface through an element guide passage formed inside the slider, the pivot shaft portion is disposed to protrude only on the first surface of the insert plate portion, the second surface of the insert plate portion is formed into a flat surface, a height dimension from the second surface of the insert plate portion to a first surface of the pivot shaft portion in a tape front and rear direction is set smaller than a distance between upper and lower blades of the slider and larger than a tape groove of the slider, the pivot support member includes a protrusion that extends toward a tape outer side from a first surface side of the box pin portion and supports the first surface side of the insert plate portion at the time of coupling of the first and second element rows and a flat plate-like support portion that extends toward the tape outer side from a second surface side of the box portion, so that the flat plate-like support portion extends behind the nearly J-shape of the box portion, and the flat plate-like support portion supports the second surface side of the insert plate portion at the time of coupling of the first and second element rows, and wherein a side end surface of the flat plate-like support portion which faces the insert member lies in a same plane surface as an outer wall surface of the box portion and the side end surface extends beyond an upper edge of the outer wall surface of the box portion in the tape length direction.
