Abstract: A power transmission apparatus for a vehicle includes a power control unit constituted by first and second clutches. An input unit is configured by configuring a number of input gears on first and second input shafts overlapped and disposed on the same axis line without rotary interference so that the rotary power of the engine is input through the power control unit. A shift output unit is constituted by first and second output shafts which are disposed in parallel to the first and second input shafts, respectively. A number of synchronization units synchronization-connect the plurality of transmission gears to the first and second output shafts. A reverse shift unit is constituted by a reverse input gear configured in one input shaft of the first and second input shafts, and a reverse transmission gear disposed on an output shaft and synchronization-connected to output shaft by the synchronization unit.
