PROBLEM TO BE SOLVED: To enable moving a long file stably in the direction perpendicular to the longitudinal direction of the file.SOLUTION: A fixing part of a file attachment jig holds the base end side of a file while positioning the file so that the longitudinal direction of the file is directed in the direction perpendicular to the reciprocating direction of an operation portion in the tool body. A file support member having a roller at the tip brings the roller into contact with the file at a position separated from the file attachment jig on the principal plane opposite to the principal plane including the to-be-used cutting part of the file attached to the file attachment jig and keeps the contact during reciprocation of the file with reciprocation of the operation portion in the tool body so as to suppress vibration in the direction perpendicular to the reciprocating direction of the file. |
