Beschreibung
Zusammenfassung:	A speed-changing device includes a motor, a reduction gear train that reduces a rotation speed of the motor in accordance with a speed reduction ratio and transmits the rotation at the reduced speed, and a speed reduction ratio switching unit that switches the speed reduction ratio. The speed reduction ratio switching unit includes an actuator that switches the speed reduction ratio, a controller that controls the actuator, and a drive state detector that detects an index value representing load torque applied to the motor. The controller activates the actuator when the index value exceeds a first threshold value and activates the actuator when the index value fluctuates between the first threshold and a second threshold thereby forming an undulated pattern that satisfies a predetermined condition.
