In a small rotary tool configured to rotate an output shaft at the tip with a motor, the motor is attached to a side surface of a first internal gear that meshes with an external gear attached to the rotation shaft of the motor via a planetary gear. An annular groove that is open on the side is formed, and a circular hole window is formed on the side of the closed output side from which the steel ball protrudes, and the steel ball, an annular ring, a corrugated plate spring, and an annular ring are sequentially inserted into the annular groove from the output side. A clutch knob is disposed in which the movable plate is inserted and moved back and forth in the axial direction via a movable plate from the back side, and at least a part of the movable plate is exposed on the outer peripheral portion of the tool body, and the output shaft of the first internal gear is A clutch plate having a locking portion on the side thereof is disposed, and by operating the clutch knob, the repulsive force of the corrugated leaf spring that presses the steel ball is adjusted, and the engagement between the first internal gear and the clutch plate is adjusted. A variable torque adjustment mechanism configured to adjust rotational torque by changing stopping force is provided, and at least one of the internal gears constituting the reduction gear is configured to rotate with respect to the tool frame. A small rotary tool characterized by:
