PURPOSE: To achieve improved frictional rolling by a tool with a smoothing rolling head. CONSTITUTION: A support member 9 having a face 10 curved cylindrically to be concentric with a conical traveling track is supported on a bearing member 1 having an assigned cylindrical curved face rotatably and movably in the axial direction, and in that case, the support member 9 and the bearing member 1 are connected to each other through an entraining body. The entraining body comprises a groove 34 formed by at least one face curved like at least one assigned cylinder and passing at a non-self locking helix angle and at least one entraining body 32 which lockes in at least one groove to cooperate with at least one groove, wherein at the time of exceeding to the balancing turning torque at the support member 9 to the adjusting force 29, the support member is moved in the opposite direction to the direction of the adjusting force 29 in the axial direction. |
