In a four parallel shaft type automatic transmission, the driving force of a main shaft is transmitted to a first sub-shaft and a second sub-shaft via a gear train. A first speed clutch provided on the first sub-shaft and a fourth spe ed clutch and a fifth speed - reverse clutch provided on the main shaft on the left-hand side of the gear train are placed so that they are aligned in a direction perpendicular to the shafts, and a second speed clutch provided on the first sub-shaft and a third speed clutch provided on the second sub-shaft on the right-hand side of the gear train are placed so that they are aligned in a direction perpendicular to the shafts. Therefore, the overall axial length o f the five clutches can be shortened so reducing the size of the automatic transmission.
