TRANSMISSION STRUCTURE OF WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a transmission structure which is able to shorten a distribution route of oil to a hydraulic power unit for working device. SOLUTION: The transmission structure is constructed in that the driving power from a driving source is inputted to the power input shaft for driving a working device housed in a transmission case, a hydraulic power unit for the working device and a valve unit for feeding, scavenging and controlling pressure oil are provided in a connected raw arrangement along the vehicle longitudinal direction on one side of the vehicle cross direction in an upper position in the transmission case or on an upper surface thereof and a hydraulic pump driven through the power input shaft is disposed on the other side of the vehicle cross direction of the hydraulic power unit and valve unit, thereby supplying oil in the transmission case from the lower side of the hydraulic pump to the suction port of said pump and further the delivery port of the hydraulic pump is connected to the oil receiving port of the valve unit.
