Abstract

See full text

A drive device includes a driven body provided on an opening of a case, and a polymer actuator which is bent and deformed in a height direction and movably supports the driven body in the height direction. A first conductive portion is provided on the case side, a second conductive portion is provided on the driven body side, and the first conductive portion and the second conductive portion configure a plurality of contact portions. When the driven body is raised by the polymer actuator, the first conductive portion and the second conductive portion come into contact with each other by the plurality of contact portions, and thus, the raised state of the driven body is detected.
