PURPOSE: A linear actuator and a wearable robot using the same are provided to smoothly flow hydraulic fluid by conforming piston operating direction and hydraulic fluid discharging direction with lightweight planning. CONSTITUTION: A linear actuator(1) comprises a piston(100), a cylinder(200), a cylinder housing(300), and a top stopper(500). The piston is formed with tube shape. A filler(150) is filled inside of the piston. The cylinder is formed with tube shape and is coupled with the piston while sliding inside. The cylinder housing is formed with a lightening material and surrounds the cylinder. A lower part stopper is combined with the cylinder where the cylinder is combined with the piston. The lower part stopper prevents the cylinder housing from separating. The top stopper is combined with the cylinder in the opposite side of the lower part stopper and prevents the cylinder housing from separating.
