This patent pertains to a fluid pressure actuator equipped with a rubber tube and a multi-layer woven sleeve. The design of the sleeve minimizes the exposure of the rubber tube, enhancing its durability. The inner layer of cords is arranged at a large angle, while the outer layer is arranged at a small angle, increasing contraction force while reducing the exposure of the rubber tube. This design achieves a fluid pressure actuator that can endure prolonged use.
