<P>PROBLEM TO BE SOLVED: To perform operations different from before such as a two-direction operation. <P>SOLUTION: A balloon actuator (5a, 5b, 5c) is provided in which the film body (11, 12) of a surface is expanded while being stretched by the fluid pressure of a fluid supplied to the inside and bending motion is performed by tensile stress generated by the stretch. The film body (11, 12) is provided with: a first film body (11) to be stretched by a fluid pressure; and a second film body (12) constituted so that it is to be stretched by the fluid pressure and the tensile stress generated by the stretch is different from the first film body (11), and joined to the first film body (11) so as to supply the fluid between the first film body (11) and the second film body (12). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
