Slider for slide fastener and slide fastener including the same

A slider for slide fastener, the slider comprising:

• a slider body including:
• an upper wing, a lower wing, an interconnection pillar interconnecting the upper wing and the lower wing, a passage for fastener elements defined by the upper wing, the lower wing and the interconnection pillar, and an insertion hole extending toward the lower wing from an insertion entrance on a side of the upper wing so as to form a hollow in the interconnection pillar;
• a pull tab mounted onto the slider body so as to be pivotable over the upper wing between a collapsed posture and an upright posture;
• a spring member mounted onto the slider body so as to fit in a portion of the pull tab, the spring member including a front leg, a rear leg, and an intermediate portion extending between the front leg and the rear leg, the front leg inserted into the insertion hole via the insertion entrance, and the rear leg including a pawl tip projectable into the passage for the fastener elements via a pawl slot penetrating through the upper wing at a rearward position of the insertion entrance;
• and
• a cover attached to the slider body so as to cover at least the spring member, wherein
• the spring member is not mechanically fastened to the slider body and the cover, such that an entirety of the spring member is displaceable in a space between the slider body and the cover in accordance with a force applied from the pull tab when the pull tab is operated,
• the front leg is shaped as a flat plate, and
• the cover is configured to include a limiting portion, which is formed as a protrusion inside a cover groove of the cover, that limits, at a position over the insertion hole, upward displacement of the front leg of the spring member, thereby the spring member being supported as a cantilever based on corporation of the slider body and the limiting portion of the cover.
