PROBLEM TO BE SOLVED: To provide a fluid-pressure actuator allowing a motor to be eliminated and a moving part to be reduced in weight. SOLUTION: This actuator 10 comprises a guide shaft 11 and a slider 12 movable along the guide shaft 11. A pressure chamber is formed between the periphery of the guide shaft and the slider, and a partition wall 13 axially dividing the pressure chamber into two cylinder chambers 16a and 16b is installed in the slider so that compressed air is allowed to enter and exist the cylinder chamber divided into the two parts through a passage 11-1 provided in the guide shaft. In particular, the slider is made to titanium.
