PROBLEM TO BE SOLVED: To provide a hydraulic structure for a combine which is constituted so as to actuate and control a pair of hydraulic actuators for steering a vehicle and a hydraulic lift device for lifting up and down a reaping/conveying device by pressure oil from a single auxiliary hydraulic pump body, and reducing the pressure loss of the supplemental hydraulic pump body as much as possible. SOLUTION: In the hydraulic structure, a steering valve unit for controlling hydraulic oil of the pair of the hydraulic actuators is attached to a mission case, a lifting valve unit for controlling the hydraulic oil of the hydraulic lift device from the mission case so as to be closely arranged to the hydraulic lift device, and a flow-dividing valve using stored oil in the mission case as an oil source and dividing the flow of the pressure oil from the auxiliary hydraulic pump body attached to the mission case to the pair of the hydraulic actuators and the hydraulic lift device is provided at the steering valve unit.
