<p>The present invention provides a resin-made slider of the type that a pull tab is to be attached afterward, in which after the pull tab is attached, a mouth dimension on a rear mouth side of a body is never affected even if the pull tab is pulled in any direction. A pull tab attaching lever (11) is provided in a shape of a cantilever from a rear mouth (9) side of an upper blade (2) toward a shoulder mouth (8), and has an engaging portion (16) provided at a front end portion (13) thereof. An engaged portion (20) is provided on the shoulder mouth (8) of the body (1) so that the engaging portion (16) and the engaged portion (20) can be engaged with each other. A concave portion (21) is provided in the upper blade (2) from a proximal portion (12) of the pull tab attaching lever (11) toward the shoulder mouth (8), and a gap portion (14) is formed between the upper blade (2) and the proximal portion (12). The gap portion (14) allows to form in the upper blade (2) a first upper blade portion (2a) separated from the proximal portion (12) and a second upper blade portion (2b) disposed from the proximal portion (12) toward the shoulder mouth (8) side and connected to the proximal portion (12). Even if a pull tab (30) is operated in any way after the pull tab (30) is attached to the pull tab attaching lever (11), any fault of expanding a mouth dimension (H) of the rear mouth (9) of the body (1) is eliminated to prevent chain engagement failure.</p> |
