Abstract
A twin clutch type transmission in which, when establishing a reverse gear position, the driving force of an engine (E) is transmitted to driven wheels (W, W) via the path: even-numbered gear clutch (Ce)→second input shaft ()→second input shaft gear ()→idle shaft second gear ()→idle shaft first gear ()→first countershaft first gear ()→first countershaft ()→first countershaft second gear ()→third countershaft second gear ()→first speed-third speed synchronizing device ()→third countershaft ()→third countershaft third gear ()→second output shaft gear ()→second output shaft ()→final drive gear ()→final driven gear ()→differential gear (). When establishing a first speed gear position by engaging an odd-numbered gear clutch (Co), the whole of the driving force transmission path on the downstream side of the first countershaft first gear () is shared with that when establishing the reverse gear position, thus enabling the weight and dimensions of the transmission to be reduced effectively.
