The cylinder is divided into a first and second chamber by a piston head, pressurized oil is supplied to either the first or second chamber by a switching valve, and the piston is moved within the cylinder, thereby controlling the tip of the piston. In hydraulic actuators that perform predetermined machining using tools, a through-end valve is installed in an oil passage hole provided in the piston head, and the through-end valve, which is linked to the piston, comes into contact with the cylinder base wall due to the stroke of the piston, thereby opening the oil passage. A hydraulic actuator characterized in that the pressures in the first and second chambers, which have open holes and are separated by a piston head, are the same pressure to facilitate and ensure operation of the switching valve.
