摘要： When air is supplied by an air pressure regulation part to bellows 211 through 213 of finger joint motion facilitation parts 110 j (where j=1 , ..., 5), the bellows 211 through 213 expand approximately in the shape of circular arcs, since annular grooves on the side of the bellows 211 through 213 opposing a joint are elastically restrained by elastic members 241 through 243. Due to this, the bellows 211 through 213 cooperate, and exert force in the rotational direction to flex the first through the third joints of a finger from their extended states. Next, when air is exhausted from the bellows by the air pressure regulation part, the bellows 211 through 213 contract. Due to this, the bellows 211 through 213 cooperate, and exert force in the rotational direction to extend the first through the third joints of a finger from their flexed states. The forces generated in this manner are transmitted to the joints by transmission members 231 through 234. As a result mounting becomes simple, and also it is possible to facilitate sufficient joint movement for each joint.
