摘要： When a finishing operation is performed while rotating a workpiece at a main shaft drive of a machine tool, pulsation occurring in a rotation of the main shaft drive is restricted and the rigidity of a main shaft is increased without increasing the size of a bearing. A rotation-resistance device of a main shaft drive in a machine tool has the following structure in the main shaft drive including a main shaft 4, a rotating body 65, and a driving device 6, the main shaft 4 being supported so as to be rotatable with respect to a frame body 2, the rotating body 65 being secured to an end of the main shaft 4, the driving device 6 rotationally driving the rotating body (65). The rotation-resistance device includes a damping device (10) including a damping member, which is provided at the frame body 2 or the rotating body 65 and which includes a resiliently deformable damping section, a pressing-force applying device 66, which applies a pressing force to the damping member by operating fluid, and a damping surface 32, provided at a side of the frame body 2. The damping device 10 causes the pressing force to act upon the damping section to flex the damping section, so that the damping surface 32 and a sliding surface 33 are pressed against each other, and a rotation resistance that allows rotation is applied to the rotating body 65. A low-friction coefficient member 60 is secured to at least one of the damping surface 32 and the sliding surface 33.
