DRIVER WITH MACHINE SCREW RECEIVER

PROBLEM TO BE SOLVED: To improve a drop preventing effect of a machine screw, by providing a receiving part extended toward a tip end of a shaft part from a support part further with an opening part positioned in the downward from the tip end of the shaft part in a use condition of a driver, and a positioning means positioning the support part in the shaft part. SOLUTION: In the case of performing operation of a condition extending an axial line of a machine screw 4 from the downward to the upward, a machine screw receiver 20 is mounted in a shaft part 12 so as to position an opening part 22a of a receiving part 22 in the downward from a tip end of the shaft part 12 in this mounting condition. When a screwing condition of the machine screw 4 is insufficient and it is dislocated from a tip end of the shaft part 12, the machine screw 4, tends to drop down to the downward, but in this operating condition, under the tip end of the shaft part 12, the opening part 22a of the receiving part 22 is positioned, so as to receive the machine screw 4 stopped to the receiving part 22 from this opening part 22a.
