Abstract:
1. A transmission for a vehicle with plural transmission shafts including first and second hollow shafts and a third shaft located therebetween, wherein each hollow shaft supports plural transmission gears in a row that are arranged in parallel so that mutually corresponding transmission gears are engaged and a desired speed reducing ratio is acquired by selectively switching transmission gears revolving in synchronization with the hollow shaft of every transmission shaft, comprising: a clutch mechanism provided between the first and second hollow shafts and the transmission gear for synchronizing the first and second hollow shafts and each transmission gear or releasing the synchronization; and a clutch actuator housed in the hollow shafts; said clutch mechanism selectively synchronizes each transmission gear with the hollow shafts or releases the synchronization according to the axial position of the clutch actuator, said plural transmission shafts are independently arranged relative to each other and are positioned on distinct axes, wherein power input to said first hollow shaft is transferred to said second hollow shaft via said third shaft.
