An overload detection device for a high-lift work vehicle, capable of detecting the load on the work platform with a high degree of accuracy while adopting an inexpensive device configuration is provided. A base 10 of the work platform is supported with a bracket 9 at, at least, three supporting portions. Load sensors 11 each constituted of a plate member 14 and distortion gauges 15~18 pasted onto the plate member 14 to detect the extent of its flexure are mounted at, at least, two of the supporting portions. The load sensors 11 are each mounted by connecting the two ends of the plate member 14 to the bracket 9 and the base 10 with bolts 22 and 25. Over the area where each load sensor is connected with either the bracket or the base 10, an elastic member such as disk springs 27~29, which allows a displacement of the load sensor 11 relative to the bracket 9 or the base 10 along the upward direction and the downward direction is provided.
