Claim:
A slide fastener comprising: a pair of slide fastener top end stops made of resin, each top end stop attached adjacent a top end of a fastener element row; a slider, which is attached to opposing side edges of a pair of fastener tapes and which slides along each of the fastener element rows so as to be capable of engaging and releasing the fastener elements, the slider having: a diamond connecting upper and lower blade plates of the slider; a flange disposed from each of right and left side edges of the upper blade plate toward the lower blade plate; at least one of the top end stops including a main body comprising an outer side face opposing the diamond of the slider and an inner side face opposing the flange of the slider, a projecting portion projecting sideways from the inner side face on an end portion on the opposite side to the fastener elements of the main body, which is capable of butting against a side end face of the top end of the flange of the slider, and a projecting piece disposed between the main body and the projecting portion; and wherein the projecting piece is formed from a proximal end on a side of the main body of the projecting portion to a front end thereof so that the front end of the projecting portion is connected with the inner side face of the main body; and wherein the projecting piece is thinner than the projecting portion in a direction perpendicular to a tape face of the fastener tape and that a dimension of the projecting piece in the width direction of the fastener tape is decreased gradually as it goes from a side of the projecting portion to a side of the main body.
