WEAR-TYPE JOINT DRIVE DEVICE

摘要

In a wear-type joint drive device, frame bodies are installed on a body that wears the device. The installation is made such that the frame bodies are in contact with an outer surface of the device-wearing body. Between the frame bodies are attached fluid-pressure actuators. A fluid-pressure actuator has an expansion/contraction body and a mesh-like cover body covering the outer periphery of the expansion/contraction body. The fluid-pressure actuator produces drive force when the length of the expansion/contraction body is reduced by its expansion. The frame bodies have predetermined rigidity.
