<p>The present invention relates to a decelerator structure using a plurality of two-speed spur gears, and an actuator module including same, and the decelerator structure using the plurality of two-speed spur gears for reducing a high-speed rotation of a rotary motor to a low speed so as to transfer torque to an output gear, which is provided with a teeth surface on the outer circumferential surface thereof, comprises: a first speed reduction portion comprising an upper spur gear and a lower spur gear, which is integrally formed with a lower portion of the upper spur gear, and a two-speed spur gear, which rotatably coupled to the output gear, for a first speed reduction; and a second speed reduction portion, which is formed between a last two-speed spur gear of the first speed reduction portion and the output gear, comprising at least two two-speed spur gears for a secondary speed reduction, further comprising an upper spur gear, which is in gear with a lower spur gear of the last two-speed spur gear of the first speed reduction portion, and the lower spur gear which is in gear and moves in linkage with the teeth surface of the output gear, wherein the at least two two-speed spur gears for the second speed reduction are symmetrically formed.</p> |
