Abstract
To propose a novel and improved actuator and artificial leg capable of miniaturizing an apparatus. An actuator () includes: a leaf spring () whose one end () is cantilevered, the leaf spring being capable of deflection deformation in a plate thickness direction in accordance with torque by transmitting the torque; and a support member () configured to support a part of the leaf spring on a deflection direction side in a case where the torque transmitted by the leaf spring is greater than a predetermined value.
