ABSTRACT:
The actuator of the present invention is driven by pressure changes of the fluid. A first structural body as an elastic body includes a plurality of pressure chambers along an axis direction. The first structural body passes through a second structural body, an annulus ring, with a predetermined gap between an outer surface of the first structural body and an inner surface of the second structural body. A supply unit sequentially supples fluid to the plurality of pressure chambers. A pressure welding position between the outer surface of the first structural body and the inner surface of the second structural body is sequentially changed by unit of the pressure chamber. Therefore, the second structural body rotates in response to changes of the pressure welding position.
