The front stop is oriented, when the slider is prevented from moving forward by the stop portion of the front stop, to allow a contact portion in the front region of its second side surface to touch an inner wall surface of the flange of the slider and to allow at least a part of the rear region of its first side surface to touch a wall surface of the interconnection pillar.

Slide fastener

A slide fastener includes a pair of left and right fastener stringers each having an element row at each of opposing edge portions of left and right fastener tapes, and a slider configured to engage the element rows by moving forward between the pair of left and right fastener stringers and to disengage the element rows by moving backward. The slider includes an upper wing plate, a lower wing plate , a guide pillar for connecting the upper wing plate to the lower wing plate, a Y-shaped element path defined between the upper wing plate and the lower wing plate, left and right shoulder openings that are open forward the element path, and a rear opening that is open backward the element path.

Slider for slide fastener

In at least a part of a movable range of a slider, a slider upper portion is positioned adjacent to a wall upper portion, and a slider lower portion is positioned adjacent to a wall lower portion. This prevents jamming of a cloth in the slider at both sides of the tape upper and lower surfaces.

A slider includes a resin-made slider body, a pull tab, and a metallic connecting pin. Lateral walls of the slider body and the pull tab are provided with shaft holes in which the connecting pin is inserted. The shaft holes of the lateral walls are opened on outer side surfaces of the lateral walls to define openings, a bottom edge point of each of the openings being located at a position outer in a Y-axis direction than a top edge point above the bottom edge point.

Slider and slide fastener with same

A slider for slide fastener includes: a slider body including an upper blade and a lower blade which are separate from and face each other in an upward and downward direction, and a guide post which connects the upper blade and the lower blade on a front end side; and a pull tab which is attached to the slider body. A cutout region is formed in at least one of both sides in a width direction of the upper blade, the both sides in the width direction sandwiching the guide post. The cutout region is formed of a side edge portion extending toward an outer side in the width direction of the guide post and being arranged along a front and rear direction, and a front edge portion.

A slider includes a slider body and a pull. The slider body includes an upper blade and a lower blade arranged to be spaced from each other in an up-down direction and to be parallel to each other, a guide post connecting the upper blade and the lower blade, and a pull attachment portion provided on an upper surface of the upper blade. The pull is attached to the pull attachment portion. A cut-out portion is formed on a front end portion of the upper blade at one of left and right sides with respect to the guide post. The cut-out portion is formed to be positioned at a rear side than a front end portion of the upper blade at the other of the left and right sides with respect to the guide post and than a front end portion of the lower blade.

Slider and slide fastener

There is provided a slider cover of a slide fastener. An upper mounting plate includes: an upper plate to be arranged above an upper blade of a slider and formed with a through-hole penetrating therethrough; and an upper wall protruding downward from the upper plate. A lower mounting plate includes: a lower plate to be arranged below a lower blade of the slider; and a lower wall for surrounding front, right and left sides of an outer periphery of the lower blade and protruding upward from the lower plate. At least one of the upper and lower mounting plates includes a protrusion protruding from an inner peripheral surface of at least corresponding one of the upper and lower walls and configured to come in close contact with a part of an outer peripheral surface of at least corresponding one of the upper and lower blades.

Slider cover of slide fastener and slider set

There is provided a slide cover for a slide fastener. A pair of second guide element passages are formed in a space among an upper plate, a lower plate, a pair of outer wall portions and a pair of inner wall portions to guide a pair of separated element rows into a first element guide passage of a slider. The upper plate, the lower plate and a connection post have a concave surface, which is recessed in a disengaging direction of the slider, in a surface facing toward an engaging direction of the slider. The pair of second guide element passages are configured so that tip ends of the pair of inner wall portions in the engaging direction are located at the same positions as or at a side of the engaging direction relative to tip ends of the pair of outer wall portions in the engaging direction.
