PROBLEM TO BE SOLVED: To restrain interference or a collision between a fastening part and an inner wall surface of a through-hole, when carrying the fastening part via the through-hole formed in a carrying member.SOLUTION: A carrier tube 20 comprises a T-shaped hole 28 of a cross-sectional T shape for carrying a very small screw 12. An air suction port 46 is opened on a top surface 42 on one opening 64 side of the T-shaped hole 28, and a part supply port 50 is opened on a bottom surface 44 on the one opening 64 side of the T-shaped hole 28. When air is sucked from the air suction port 46 by a suction part 24, the very small screw 12 sucked in from a part intake port 52 is inserted into the T-shaped hole 28 via the part supply port 50, and the very small screw 12 is adsorbed to an adsorption surface 46A formed on the adsorption surface 46A. The air is discharged in the T-shaped hole 28 via the one opening 64 of the T-shaped hole 28 from a discharge part 26, and the very small screw 12 adsorbed to the adsorption surface 46A is carried to the other opening 84 of the T-shaped hole 28 via the T-shaped hole 28.SELECTED DRAWING: Figure 1 |
