Abstract

　A slider (400) for a slide fastener is provided with a slider body (100) and a blocking member (200). The upper wing plate (10) of the slider body (100) is provided with a recessed placement part (70) on which the blocking member (200) is placed, and a fitting hole (75) into which the fitting projection (220) of the blocking member (200) is inserted and fitted is provided to the placement part (70) in such a way that the end of the upper wing plate (10) is cut out. The placement part (70) and the fitting hole (75) extend along the direction in which the blocking member (200) is moved in order for the blocking member (200) to be mounted in the slider body (100). The length of the fitting hole (75) in the direction of movement is less than the length of the placement part (70) in the direction of movement.

Description

technical field [0001] The present invention relates to sliders for slide fasteners. Background technique [0002] The technique of retrofitting a handle to a slider body having a cantilever-shaped handle attachment column is known. To allow rear mounting of the tab, there is a gap between the free end of the tab mounting post and the upper wing of the slider body. This clearance is required when the tab is installed post-installation, but is no longer required after the tab is installed. Therefore, in a certain method, after attaching a handle, it plastically deforms a handle attachment column, and reduces this clearance gap. However, in this case, it may be required to suppress undesired deformation of the slider body due to force applied to the handle mounting post, for example, variation in the interval between the upper blade and the lower blade. [0003] Even if the handle attachment column is plastically deformed like the above-mentioned example, a minute gap remai...
