The invention discloses a speed reducer layout structure used for a range-extending type electric vehicle, and belongs to the technical field of electric vehicle speed reducers. The speed reducer layout structure comprises a power generation transmission mechanism, a drive transmission mechanism and a differential mechanism, wherein the power generation transmission mechanism comprises a power generation input shaft, an idle wheel shaft and a power generation output shaft; the drive transmission mechanism comprises a drive input shaft and a drive output shaft; power output by an engine is transmitted into the power generation transmission mechanism through dual mass flying wheels, and rotation speed is increased by the power generation transmission mechanism through a gear wheel of each axle, so that a power generator is driven to generate power in a high-efficiency area, and therefore, electric power is provided to a whole vehicle power battery and a drive motor; power generated by the drive motor is transmi
