an engine side driving gear mounted at the input shaft; an output shaft disposed in parallel with the input shaft; an engine side driven gear fixedly mounted at the output shaft and meshed with the engine side driving gear; a motor side driving gear mounted to form a concentric shaft with the input shaft and mounted to rotate by the motor; a motor side driven gear fixedly mounted at the output shaft and meshed with the motor side driving gear; an output gear rotatably mounted at the output shaft; a one way clutch mounted between the output gear and the output shaft so as to transmit power from the output shaft only to the output gear at a time of a forward driving of the vehicle; a clutch device mounted on the output shaft and transmitting a power from the output shaft to the output gear at a time of a reverse driving of the vehicle; and a planetary gear apparatus engaging between the output shaft and the output gear. ### Claim 2 (depends on 1) The hybrid power train for the vehicle of claim 1, wherein in the planetary gear apparatus, a carrier is directly connected to the output shaft, a ring gear is directly connected to the output gear, and a sun gear is fixedly mounted at the output shaft while forming a concentric shaft, and wherein the planetary gear apparatus is provided with a brake to selectively fix a rotation of the sun gear. ### Claim 3 (depends on 1) The hybrid power train for the vehicle of claim 1, wherein the clutch device is formed of a dog clutch which is configured to convert a state of fixing and unlocking the output gear to and from the output shaft. ### Claim 4 (depends on 1) The hybrid power train for the vehicle of claim 1, wherein the clutch device is formed of a synchro mesh type synchro mechanism which converts a state of fixing and unlocking the output gear to and from the output shaft. ### Claim 5 (depends on 1) The hybrid power train for the vehicle of claim 1, wherein the engine side driving gear has a diameter larger than that of the engine side driven gear, and wherein the motor side driving gear has a diameter smaller than that of the motor side driven gear. ### Claim 6 (depends on 1) The hybrid power train for the vehicle of claim 1, wherein an engine clutch is mounted between the input shaft and an engine rotating shaft of the engine to selectively block the power to the input shaft. ### Claim 7 (depends on 6) The hybrid power train for the vehicle of claim 6, further comprising: a driving gear mounted at the engine rotating shaft; a driven gear rotatably mounted at the engine rotating shaft while forming a concentric shaft and connected a generator to rotate the generator, an idler shaft disposed in parallel with the engine rotating shaft, wherein the idler shaft is connected to a first medium gear which is meshed with the driving gear and to a second medium gear which is meshed with the driven gear for power generation.
