Abstract
Provided is a wearable joint driving device in which a plurality of frame members are attached to a wearing body so as to be in contact with the outer surface of the wearing body. Between the frame members, there is mounted a fluid pressure type actuator. The fluid pressure type actuator has an expansion/contraction member and a net-like covering member covering the outer periphery of the expansion/contraction member. The fluid pressure type actuator undergoes a reduction in length through expansion of the expansion/contraction member to thereby generate a driving force. The frame members have a predetermined level of rigidity.
