The work vehicle has engine having an engine output shaft in the middle of which a first one-way clutch is attached, a traveling drive portion having a transmission connected to the engine output shaft and a traveling drive shaft which is rotated by the transmission and which moves the traveling portion, a work drive portion having a drive shaft for work which is gear-coupled to an engine output shaft gear fixed downstream of the first one-way clutch of the engine output shaft, a switching valve provided in the work drive portion which selects whether to supply fluid to the work portion or return fluid to a tank, a first motor/generator connected to the drive shaft for work and driven by a battery, a work regeneration portion transmitting regenerative energy of the work drive portion to the engine output shaft gear via a second one-way clutch, and a second motor/generator which is gear-coupled to the traveling drive shaft and driven by the battery.",
