The tip end of the first auxiliary link 30 is rotatably connected with the tip end of the second auxiliary link 40. At least one of the rotation center of the connection part of the thigh link and the first auxiliary link and the rotation center of the connection part of the crus link and the second auxiliary link is positioned backward more than the center line in the longitudinal direction of the leg passing through the knee joint rotation axis. Further, the walking support device is structured so that, when a user extends the knee, the rotation center of the connection part of the thigh link and the first auxiliary link, the rotation center of the connection part of the first auxiliary link and the second auxiliary link, and the rotation center of the connection part of the crus link and the second auxiliary link are arranged in a line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
