Slide fastener

A slide fastener, comprising:

• a first slide fastener member and a second slide fastener member that are separable, wherein
• the first slide fastener member includes a first cloth tape, a first element row fixed on an inner edge of the first cloth tape, a slider movably attached to the first element row in a length direction of the slide fastener, and a retainer pin member fixed on the inner edge of the first cloth tape and disposed at an end of the first element row, the slider includes an upper blade and a lower blade disposed facing each other and connected to each other along a thickness direction of the slide fastener, and the upper blade and the lower blade are respectively provided with an upper flange and a lower flange protruding toward each other, and the retainer pin member includes a retainer pin main body and a retainer pin arm extending from the retainer pin main body toward the first element row,
• the second slide fastener member includes a second cloth tape, a second element row fixed on an inner edge of the second cloth tape, and a separable pin member fixed on the inner edge of the second cloth tape and disposed at an end of the second element row, and the separable pin member includes a separable pin main body, a separable pin arm extending from the separable pin main body toward the second element row, and a half element fixed to the separable pin main body and adjacent to the second element row,
• the retainer pin member and the separable pin member are rotatably engageable and are separable with respect to each other, and when the retainer pin member and the separable pin member are engaged with each other, a slider accommodating area which is enclosed by the retainer pin main body, the retainer pin arm and the separable pin arm and which is capable of accommodating the slider, is formed,
• an inclined protrusion protruding toward the slider accommodating area is provided on a side surface of the retainer pin arm facing the slider accommodating area, a flange passage is formed between the half element and the separable pin arm, and the flange passage is a part of the slider accommodating area and allows the upper flange and the lower flange of the slider on a side of the separable pin arm to pass therethrough, and
• when the retainer pin member and the separable pin member are engaged with each other and the slider is located in the slider accommodating area and abuts against the retainer pin main body, the inclined protrusion abuts against an outer peripheral side of the slider and drives the slider to be inclined toward the separable pin member.
