Abstract: A through-hole of a hydraulic chamber is provided on an input side of a thrust expansion device in accordance with rod diameters of various actuators on the input side, and an input rod of an air cylinder or the like is inserted therein. Thus, a thrust expansion mechanism operates. An input-side actuator attaching portion of the thrust expansion device is configured such that parts can be changed according to a fixing method of various actuators and a rod shape. It is possible to freely change a thrust expansion ratio by changing a cross sectional area of the input rod. A stroke of an output-side rod can be changed by changing an input stroke of the input-side actuator. According to the thrust expansion device, various inexpensive commercially available actuators can be easily attached and replaced by being separated and independent from the input-side actuator.
