Abstract
A super magnetostrictive actuator includes: a magnetic field generating unit, at least first and second super magnetostrictive members extensible in a longitudinal direction thereof due to action of magnetic field generated by the magnetic field generating unit, and a coupling member having a cylindrical shape and disposed coaxially between the first and second super magnetostrictive members. The second super mangetostrictive member has a cylindrical shape and is coaxially disposed to surround the outside of the first super magnetostrictive member in a radial direction thereof. Both end portions of the coupling member are coupled to one end portion of the first super magnetostrictive member and one end portion of the second super magnetostrictive member, respectively.
