The present disclosure relates to a speed reducer and, more specifically, to a speed reducer for power transmission of a parallel drive system for a variable capacity electric commercial vehicle. A speed reducer for power transmission of a parallel drive system for a variable capacity electric commercial vehicle, according to an embodiment of the present disclosure, comprises: a first motor disposed inside a housing and including a first rotor shaft for transmitting rotational force; a second motor disposed in parallel with the first motor disposed inside the housing and including a second rotor shaft for transmitting rotational force; a first gear coupled to the first rotor shaft; a second gear coupled to the second rotor shaft; a third gear rotating in engagement with the first and second gears by the rotation of the first and second motors; and a shaft which transmits power by rotation of the third gear. By installing the two motors on the speed reducer, parallel driving efficiency can be maximized according to operation conditions.
