Title:
ACTUATOR AND ARTIFICIAL LEG
Document Type and Number:
WIPO Patent Application WO/2023/047642
Kind Code:
A1
Abstract:
The present disclosure relates to an actuator and an artificial leg that make it possible to propose an actuator and an artificial leg in which the device size can be reduced. This actuator comprises a bent part that is bent in a U shape, and a first extending part that extends from the bent part. A first end part, which is the bent-part-side end part of the first extending part, is supported in a cantilevered manner. The first extending part is provided with: a plate spring that transmits torque, thereby being capable of flexing and deforming in the plate thickness direction in accordance with the torque; and a first support member that, when the torque transmitted by the first extending part in the first direction is greater than a prescribed value, supports a portion of the first extending part on both flexing-direction sides. This technology can be applied to artificial legs, for example.
