ばならないという問題があった。In a working condition of a power tool having a feeder assembly for sequentially transferring fasteners to the tip of a bit, a width such that a gypsum board or other surface material cannot be seen from the operator side. Since the width of the base material does not seem to be narrow in the work of fixing it to a narrow base material, if the screw is tightened to a part harder than the surroundings such as a node, the screw will float above the surface material as a result. was there. In addition, there was a problem that the screw could not be tightened and fell down, and it was necessary to repair it. However, when the power tool shown in FIG. 12 is reworked, it is possible to remove the feeder assembly, so a tool for removing the feeder assembly must be prepared. . Further, in the electric power tool shown in FIG. 13, the feeder assembly or the main body housing had to be rotated many times in order to remove the feeder assembly. For this reason, the work is inefficient, and there is a problem in that another tool dedicated to rework must be prepared.
