Abstract
A magnetostrictive brake is provided with an electrically-driven actuator for moving friction materials back and forth toward a rotary member by utilizing a magnetostrictive element which extends and contracts by means of magnetostriction, a fluid-type displacement enlarging mechanism which is provided between the magnetostrictive element and the friction materials and used for enlarging the displacement of the magnetostrictive element and transmitting the enlarged displacement to the friction materials, and bias magnetic field applying means for applying a bias magnetic field to the magnetostrictive element.
