Abstract
An actuator body and a throttle mechanism that are small and have a simple structure are provided. The actuator body comprises a polymer actuator 11 that bends and deforms by an electric driving source, an intermediate 12 that transmits the bending force of the polymer actuator, and an elastic body 13 to which the bending force is applied through the intermediate, wherein the dimension of a hole portion that is formed in the elastic body 13 changes when the bending force of the polymer actuator 11 is applied onto the elastic body 13 through the intermediate 12.
