| 摘要 | A slider of a slide fastener is free from any damage that may arise when a lug (4) is deformed and springs back and an upper wing (1) is protected against undesired deformation. A pair of rear lateral legs (4b, 4b) project downward from the lug (4). A gap (D) is defined between the rear lateral legs (4b, 4b) and the upper wing (1). One or more longitudinal ribs(4d) are formed on the lower surface of the lug (4). If excessively pinching force is applied to the lug (4) to close the gap (D), the upper wing is kept free from any local deformation because the rear lateral legs (4b) absorb the excessive force. Also, if the lug (4) springs back, because the rear lateral legs (4b) restore their original positions, they are held in close contact with the upper wing. | ||||||
