Problems solved by technology

Therefore, in the case of manufacturing the slider body 100 having such a structure by die-casting, the structure of the mold is extremely complicated, so there is a problem that the cost of the slider 90 is greatly increased.
[0032] Furthermore, in the slider 70 of Patent Document 1 and the slider 90 of Patent Document 2, when the cover members 71, 91 are attached to the slider main bodies 80, 100, the elastic pieces 73 of the cover members 71, 91, 93 (particularly, the bent portion of the elastic piece 73, 93) is exposed on the front side of the slider main body 80, 100, and for example, when the slider 70, 90 is slid along the engaging direction, the elastic piece 73, 93 is present. Disadvantages of being vulnerable to damage from impact with external parts

Abstract

This slider (1, 2, 3) has: a slider body (10, 10a, 50) provided with first and second mounting sections (20, 30); a pull tab (8); and a cover member (40, 40a, 60). The cover member (40, 40a, 60) is provided with: latch sections (43, 63) extending forward from the cover body (41, 61); and a stop claw section (45, 65). The first mounting section (20) is provided with: left and right first side wall bodies (21); a first connection bar (22) for connecting the first side wall bodies (21); and a housing space (24) disposed between the first connection bar (22) and an upper wing plate (11, 11a, 51) and housing the latch sections (43, 63). The housing space (24) penetrates through the first mounting section (20) in the length direction of the slider. As a result of the configuration, the manufacturing cost of the slider (1, 2, 3) is reduced, the first mounting section (20) can be reinforced by the first connection bar (22), and an elastic section (42, 62) can be protected.

Description

technical field [0001] The present invention relates to a slider for a slide fastener having a stop mechanism, and particularly relates to a slider configured by covering an attachment shaft portion of a handle with a cover member and attaching the cover member to a slider main body. Background technique [0002] As sliders used for slide fasteners, various types of sliders are conventionally used. As one of these many sliders, it is known that the cover member can be assembled to the slider main body with the handle sandwiched between the cover member and the slider main body, thereby completing the attachment of the handle. As for the slider, examples of such a slider are disclosed in, for example, JP-A-2007-111351 (Patent Document 1) and JP-A-7-21123 (Patent Document 2). [0003] Such as Figure 16 As shown, the slider 70 described in Patent Document 1 includes a slider body 80 , a handle 78 having a mounting shaft portion (pivot) 79 , and a cover member 71 attached to t...
