Claim 9:
10. An actuator band comprising a plurality of actuator single wires, wherein
the plurality of the actuator single wires are braided, knitted or woven;
first ends of the plurality of the actuator single wires are connected to each other;
second ends of the plurality of the actuator single wires are connected to each other;
each of the plurality of the actuator single wires comprises an actuator wire, and a mesh-shaped heating element which covers a side surface of the actuator wire and comprises a plurality of heating wires;
the actuator wire is formed of a fiber consisting of a polymer;
the fiber is twisted around the long axis thereof;
the fiber is folded so as to have a shape of a cylindrical coil;
the actuator wire is contracted by heat and restored by release of the heat;
a first end of the mesh-shaped heating element is connected to a first end of the actuator wire; and
a second end of the mesh-shaped heating element is connected to a second end of the actuator wire,
wherein the actuator band is configured to be contracted along the longitudinal direction thereof by heat in a state where tension has been applied along the longitudinal direction thereof, the heat provided by supplying power to the mesh-shaped heating element.
