A speed changing apparatus is described for a working vehicle of the type having an engine and traveling means to permit the vehicle to travel over the surface of the ground. The apparatus consists of: an input shaft operatively connected to the engine; and output shaft coaxially aligned with the input shafts and operatively connected to the traveling means; a fifth intermediate shaft provided between the input shaft and the output shaft; a first intermediate shaft and a third intermediate shaft coaxially aligned with one another and together comprising first transmission line means to transmit power from the input shaft to the fifth intermediate shaft; a second intermediate shaft and a fourth intermediate shaft coaxially aligned with one another and together comprising second transmission line means to transmit power from the input shaft to the fifth intermediate shaft; a first synchromesh type change speed gear means for effecting speed changes between the input shaft and the first intermediate shaft; a second synchromesh type change speed gear means for effecting speed changes between the input shaft and the second intermediate shaft; a third synchromesh type change speed gear means for effecting speed changes between the third intermediate shaft and the fifth intermediate shaft; a fourth synchromesh type change speed gear means for effecting speed changes between the fourth intermediate shaft and the fifth intermediate shaft; first hydraulically operated frictional clutch means operatively disposed and coaxially aligned between the first intermediate shaft and the third intermediate shaft for directly interconnecting the first and third intermediate shafts for a direct drive therebetween; and second hydraulically operated frictional clutch means operatively disposed and coaxially aligned between the second intermediate shaft and the fourth intermediate shaft for directly interconnecting the second and fourth intermediate shafts for a direct drive therebetween.
