PROBLEM TO BE SOLVED: To provide a hydraulic cylinder for a loading space lifting device, capable of improving maintainability and performing stable operation with high accuracy.SOLUTION: Two hydraulic cylinders 30, 40 includes selector valve chambers 38, 48 attached to bottom side end surfaces of tubes 34, 44, respectively. The selector valve chambers 38, 48 each have a valve body driven with pressing force or attracting force due to rods 32, 42 of the attached hydraulic cylinders 30, 40. With movement of each valve, a supply and exhaust state of driving pressure oil supplied to itself or the other hydraulic cylinder 40, 30 is switched.SELECTED DRAWING: Figure 3
