Abstract of the Disclosure A pneumatic actuator includes an elastic tubular body, closure members sealingly closing its ends and a braided structure made of braided cords reinforcing the tubular body. The braided structure is expanded in its radial direction and simultaneously contracted in its axial direction together with the tubular body when pressurized fluid is supplied into the tubular body. According to the invention the braided cords of the braided structure comprises monofilaments each having a smoothly rounded outer surface of a large radius of curvature. A protective layer may be provided between the tubular body and the braided structure or a filler such as an incompressible fluid substance having no constant shape is provided in the tubular body, or diameters of both ends of the braided structure and braided angles at both the ends are made larger than those at a substantially mid portion of the braided structure. The actuator according to the invention decreases damage of the tubular body to elongate its service life and exhibits an improved contacting performance and high fatigue strength and can greatly save air consumption to eliminate the disadvantage of much air consumption of the air-bag type actuator without adversely affecting its advantages.
