Therefore, the workability at the construction site is good, and there is no need to leave a large amount of nuts and washers attached to the anchor member.

Further, instead of the protrusions on the outer ring of the anchor application tool, the inner ring is located between the outer ring and the chuck and is loosely fitted, and the rollers are restricted by the inner ring. As the outer ring rotates, the roller also slides and rotates between the outer ring and the chuck to open and close the movable chuck portion, which has the same effect as described above. Since it is supported by the chuck of the tool body via the roller, the outer ring is not easily deformed by an external force, and the outer ring can always be rotated.

Further, if the two rollers are regulated by 180 degrees on the inner ring, even if there is a shock at the time of driving the anchor member by the anchor driving machine, the outer ring is applied with the tool through the roller. Since the force that is supported by the chuck of the main body and that tries to deform the outer ring is partially converted into the tension, the outer ring can be constantly rotated without further deformation.

If the tool body is divided into a connecting end and a chucking end, even if the anchor members having different diameters are selected and attached to the connecting end, the chucking end can be used. it can. Therefore, even anchor members having various diameters can be dealt with by simply exchanging the chuck end portions, and the use of the anchor driving machine is not restricted by the diameters of the anchor members.
