FILM-TYPE ACTUATOR AND FILM-TYPE ACTUATOR FITTING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a film-type actuator which does not require application of a tensile force during installation, and a film-type actuator fitting structure that can apply the tensile force without voltage impression during the installation.SOLUTION: The film-type actuator 10 includes: a core material 12; film-type piezoelectric elements 14 which are attached to both faces of the core material 12 and expand/contract the core material 12 according to an impressed voltage; a fixture 16 fixed to both end parts of the core material 12; and a holding member 18 for holding the core material 12 while a tensile force is applied between the fixtures 16.
