1. A power transmitting apparatus for a vehicle comprising:
a first input shaft adapted to selectively receive torque of an engine; a second input shaft disposed without rotational interference with the first input shaft, adapted to selectively receive the torque of the engine, and having at least one input gear fixedly disposed thereon; a third input shaft disposed in a row with the second input shaft, and having at least one input gear fixedly disposed thereon; a motor/generator operated as a motor or a generator; a planetary gear set including a first rotation element directly connected to the motor/generator, a second rotation element directly connected to the third input shaft, and a third rotation element directly connected to the first input shaft; a first speed output shaft adapted to convert torque input from the second input shaft or the third input shaft and output a converted torque; and a second speed output shaft adapted to convert torque input from the second input shaft or the third input shaft and output a converted torque, wherein a first input gear for achieving a reverse speed or a second forward speed and a second input gear for achieving a fourth forward speed or a sixth forward speed are fixedly disposed on the second input shaft, and wherein a third input gear for achieving a seventh forward speed, a fourth input gear for achieving a first forward speed, a fifth input gear for achieving a third forward speed, and a sixth input gear for achieving a fifth forward speed are fixedly disposed on the third input shaft.
