PROBLEM TO BE SOLVED: To provide a rotary tool which can achieve optimum manipulating feeling by adjusting an elastic reaction force to be applied on a tool body. SOLUTION: The rotary tool 10 comprises a rotary shaft member 12 to be fixed to a driving shaft Sp so as to rotate together with the driving shaft Sp, the tool body 14 to be mounted on the rotary shaft member 12, a nut member 18, and a belleville spring 16. The rotary shaft member 12 comprises a mounting portion 22 on which the tool body 14 is mounted so as to integratedly rotate together with the rotary shaft member 12 and so as to displace in the axial direction of the rotary shaft member 12, a flange portion 20 which is located on the front side than the mounting portion 22 and restricts the disengagement of the rotary shaft member 12, and a male screw portion 24 which is provided on the rear side than the mounting portion 22 and is engaged with the nut member 18. Further, the belleville spring 16 is arranged between the nut member 18 to be mounted on the rotary shaft member 12 and the tool body 14 in an elastically compressed state.
