ABSTRACT

An actuator includes: a plurality of wires, one end of each wire of the
plurality of wires being engaged with a load; a support member, another end of
each wire of the plurality of wires being fixed to the support member; and a
drive source configured to rotate the support member, to thereby twist the
plurality of wires together, the actuator being configured to change a
distance between the support member and the load in accordance with the
rotation of the support member. Each of the plurality of wires is fixed to the
support member in a state in which the plurality of wires are twisted in
advance in the same twist rotation direction, and when the distance between
the support member and the load is reduced, the plurality of wires are rotated
in a rotation direction the same as the twist rotation direction and then
twisted together.
