ナ。 In a nut runner that is rotatably driven by a drive source to tighten nuts, bolts, etc., the rotation of the output shaft can be changed between low-torque high-speed rotation and high-torque low-speed rotation, an input shaft connected to the drive source and rotationally driven; a plurality of protruding pieces protruding from the outer circumferential surface of the input shaft at intervals in the circumferential direction; planetary gears that are always meshed and can freely revolve around the input shaft as the input shaft rotates; A slider that is rotatable around the axis of the input shaft as the output shaft rotates, and a plurality of engagements formed in the axial direction of the input shaft on the inner surface of the slider so as to be able to engage and detach from each projecting piece. a groove, and an output side engagement part provided at the end of the slider on the planet gear side so as to be removable from the input side engagement part formed at the end of one side of the protruding shape of the planet gear. The slider is moved in the axial direction of the input shaft, so that either the engagement groove or the output side engagement portion is connected to the corresponding projecting piece or the input side engagement portion. A nut runner characterized in that the rotation of the output shaft is changed into low torque high speed rotation and high torque low speed rotation when the output shafts are engaged with each other.
