Claim:
A separable bottom end stop for a slide fastener, comprising: a separable pin which is integrally formed in one end of an element row of one fastener stringer of a pair of left and right fastener stringers where element rows are formed in facing tape side edge portions of left and right fastener tapes; and a box pin which is integrally formed in one end of the element row of an other fastener stringer, wherein the box pin includes a box pin body, a first notch portion which is notched in a first surface of the box pin body from a side of a separable pin facing surface toward an inner portion of the box pin body so as to receive a front end portion of a locking pawl of a reverse-opening slider, a protrusion piece which protrudes from the separable pin facing surface of the box pin body toward a side of the separable pin in a tape width direction, wherein a side wall surface which is disposed to the first notch portion on a side of the element row and a sectional surface which is disposed to a box pin front end side of the protrusion piece are formed in one plane and constitute a locking plane which contacts with the front end portion of the locking pawl which is received in the first notch portion to stop the reverse-opening slider, wherein the box pin body and the protrusion piece are configured to have a slant surface ( 28 , 28 ′) which is downwardly slanted from a position of the locking plane toward the side of the element row on a tape surface side of the fastener tape so as to guide the locking pawl toward the first notch portion when the box pin is inserted into the reverse-opening slider, and wherein the reverse-opening slider passes through the element rows and the locking pawl can stop the reverse-opening slider with respect to the element rows on a side of an element guide lane into which the box pin is inserted.
