摘要 |
A pneumatic actuator for use in a vibration damping device comprising: a base housing; an elastic wall member being fastened fluid-tightly to the base housing to form a working air chamber therebetween; and an urging member positioned within the working air chamber for exerting urging force on an output portion provided to the elastic wall member, such that the output portion is actuated to undergo displacement in opposition to the urging member through change in an air pressure in the working air chamber from an outside. At least one of opposing faces of the base housing and the elastic wall member on the working air chamber side thereof has a plurality of rib portions which extend from an inner circumferential side thereof towards an outer circumferential side thereof.
