Abstract:
An actuator apparatus of the present invention includes a movable body that is arranged so as to be movable forward or rearward, and a shape memory alloy wire that is provided directly or indirectly to the movable body so as to enter a non-tension state at an ordinary temperature. The shape memory alloy wire is subjected to expansion/contraction control in which an electric current is applied thereto from a power supply portion of an external control circuit portion to change a temperature thereof to a predetermined temperature.
