Abstract

See full text

Provided is a pneumatic actuator having improved durability. A pneumatic actuator (10) comprises an actuator body (100) including: a cylindrical tube (110) configured to expand and contract by air pressure; and a cylindrical sleeve (120) formed by weaving cords (121) oriented in predetermined directions, wherein in a no-load and no-pressure state, an average angle (Θ1) of the cords (121) with respect to an axial direction (DAX) of the actuator is 20 degrees or more and less than 45 degrees, and in a state in which an average angle (Θ3) of the cords (121) with respect to the axial direction (DAX) of the actuator is 45 degrees with an air pressure of 5 MPa, a ratio (S2/S1) of a total area (S2) of gaps (122) of the cords (121) to an area (S1) of an outer surface of the actuator body (100) is 35% or less.
