Abstract

A power transmission unit for an automotive vehicle having a clutch, a change speed gearing and a final drive compactly arranged with each other. A power output shaft of the clutch extends coaxially with a crankshaft of an engine. The change speed gearing has a main shaft and a counter shaft both disposed downwardly from and in parallel with the power output shaft. On the main and the counter shafts are carried change speed gear trains which are operatively coupled to the power output shaft of the clutch and are disposed downwardly rearwardly from the clutch. The final drive is arranged below the engine adjacent to the front end of the clutch. The final drive and the front end of the main shaft of the change speed gearing are connected through a drive pinion shaft which is disposed immediately below the clutch and extends coaxially with the main shaft. With the arrangement that the drive pinion shaft is disposed immediately below the large clutch, the entire unit is made compact.
