Abstract
To propose a novel and improved actuator and artificial leg capable of miniaturizing an apparatus. An actuator (320) includes: a leaf spring (322) whose one end (322a) 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 (324) 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.
Claims10
An actuator comprising:
- a leaf spring having a first end that is cantilevered at a first point of the leaf spring, the leaf spring extending along a first direction to a second end that is free, the leaf spring being capable of deflection deformation along a second direction, different from the first direction, in accordance with torque applied to a first surface of the leaf spring at the second end, the leaf spring transmitting the torque;
- and
- a support member configured to support a part of the leaf spring on a second surface of the leaf spring, opposite the first surface, and on condition that the torque transmitted by the leaf spring is greater than a predetermined value, the support member contacts the second surface of the leaf spring such that the first end of the leaf spring is cantilevered at a second point of the leaf spring closer to the second end than the first point.
