Abstract (en)

[origin: EP1293299A2] A belt-retaining member (34) is disposed in a slider member (33) of a driving gun 3, and includes an engaging finger (34F) with a pointed front end (340) , an enlarged rear end (344) , and upper and lower sliding faces (341, 342) that extend divergently and rearwardly from the pointed front end 340 toward the enlarged rear end (344). The upper and lower sliding faces (341,342) are in frictional contact with a periphery of a retaining notch unit (401) formed in a screw feed belt (40) to permit the periphery of the retaining notch unit (401) in the screw feed belt (40) to overcome friction between the periphery of the retaining notch unit (401) and the upper sliding face (341) for sliding downwardly along the upper sliding face (341) when the screw feed belt (40) is drawn downwardly, and to permit the periphery of the retaining notch unit (401) to overcome friction between the periphery of the retaining notch unit (401) and the lower sliding face (342) for sliding upwardly along the lower sliding face (342) when the screw feed belt (40) is drawn upwardly. <IMAGE>
