Abstract:
1. A polymer actuator being driven by extension and contraction of a polymer by electrical stimulation; the polymer actuator comprising: a polymer film member configured by the polymer; a first terminal member connected to one end of the polymer film member; a second terminal member connected to the other end of the polymer film member; and a movable body connected to the second terminal member by way of a first elastic body and capable of being pressed against a first terminal member side; wherein a displacement generated by extension and contraction of the polymer film member is taken out by way of the movable body connected to the second terminal member which is connected to the other end of the polymer film member, by way of the first elastic body and pressed against the first terminal member which is connected to the one end of the polymer film member, by an elastic force of the first elastic body.
