Claim:
1. A 10-stage dual clutch transmission (DCT) for a vehicle, comprising: a first input shaft receiving power through a first clutch; a second input shaft disposed coaxially with the first input shaft and receiving power through a second clutch; odd driving gears disposed on the first input shaft to implement odd gear shift steps of a 1st gear shift step to a 9th gear shift step; even driving gears disposed on the second input shaft to implement even gear shift steps of a 2nd gear shift step to a 8th gear shift step; a first output shaft and a second output shaft each disposed in parallel with the first input shaft and the second input shaft; odd driven gears each disposed on the first output shaft or the second output shaft to implement the odd gear shift steps by engaging with the odd driving gears; even driven gears each disposed on the first output shaft or the second output shaft to implement the even gear shift steps by engaging with the even driving gears; and a joint synchro disposed on the first output shaft or the second output shaft and selectively coupling any one of the odd driven gears on the corresponding shaft to any one of the even driven gears, wherein the odd driving gears on the first input shaft comprise a first driving gear for implementing the 1st gear shift step, a third-fifth driving gear for implementing a 3rd gear shift step and a 5th gear shift step, and a seventh-ninth driving gear for implementing a 7th gear shift step and the 9th gear shift step, and wherein the even driving gears on the second input shaft comprise a second driving gear for implementing the 2nd gear shift step, a fourth-reverse driving gear for implementing a 4th gear shift step and a reverse gear shift step, and a sixth-eighth driving gear for implementing a 6th gear shift step and an 8th gear shift step.
