PROBLEM TO BE SOLVED: To provide a cutting tool capable of avoiding any re-grinding of a recessed groove when the groove is worn or any re-manufacture of a slider accompanied thereby, and reducing the labor required for the maintenance even when the wear is generated. SOLUTION: A spacer 13 having a sliding surface 13a which is brought into slidable contact with the slider 16 is interposed in an attachable/detachable manner between one wall surface 11a out of the recessed groove 11 formed along the generating line of a tool body and the slider 16, a plate 14 having an engaging surface 14k to be engaged with the slider 16 is interposed in an attachable/detachable manner between the other wall surface 11b and the slider 16, and a pressing means 15 for bringing the engaging surface 14k by pressing a part of the plate 14 to elastically deform the part is provided on the other wall surface 11b.
