Screw guide structure of screw driver for collated screws

摘要

A screw guide structure of a screw feeding mechanism of a screw driver (10) is provided. The screw feeding mechanism is configured to sequentially feed collated screws (50) to a driving position. The collated screws (50) are plurality of screws (51) connected by a connecting band (52). The screw guide structure includes a base part (24), a nose member (30) provided on a distal end of the base part (24) in a slidable manner, and a straight-driving guide member (41) supported by the nose member (30) in a displaceable manner so as to guide a screw (51) fed by the screw feeding mechanism to be in a straight posture. The straight-driving guide member (41) has a concave guide groove (41b) configured to guide a shaft (51a) of the screw (51). The straight-driving guide member (41) is configured and arranged such that the shaft (51a) of the screw (51) is engaged into the guide groove (41b) when the screw (51) is fed by the screw feeding mechanism, and such that the straight-driving guide member (41) is displaced when a head (51b) of the screw (51) passes by driving the screw (51) engaged into the guide groove (41b).
