PROBLEM TO BE SOLVED: To positively feed bolts one by one into fastening holes with simple structure. SOLUTION: A cylindrical body 22 is provided with a sliding member 24 slidable in the axial direction. The sliding member 24 is provided with a plate spring 23 operated together. The plate spring 23 is provided with a protrusion 23a for locking the bolt 30, and an inclined part 23b for retreating the protrusion 23a. The cylindrical body 22 is formed with an opening 28 through which the protrusion 23 can be inserted. When the sliding member 24 is slid in a direction X1 in a state of putting a tip face 22a of the cylindrical body 22 to the predetermined fastening hole, the plate spring 23 is retreated outward by the inclined part 23b to release the locked state of the bolt 30 by the protrusion 23a. When the sliding member 24 is returned in a reverse direction, the protrusion 23a is immediately reset into a state of being able to lock the bolt 30. COPYRIGHT: (C)2005,JPO&NCIPI
