| 1. A body orthosis having a pair of body protective members adjacent to each other in a vertical direction, in which one of
the body protective members is rotatable with respect to the other body protective member, the body orthosis comprising:
rotational load setting means for setting a rotational load in one rotational direction of the rotatably constructed body
protective member larger than a rotational load in the other rotational direction,
wherein the rotational load setting means includes a one-way bearing provided in a rotary shaft portion of the rotatably constructed
body protective member,
wherein the body orthosis includes a sole plate for loading and supporting at least a part of a sole, and a leg protective
plate for protecting at least a part of a leg, and side ends adjacent to these plates are connected to each other by the rotational
load setting means, and
wherein in the case of walking by using the body orthosis, the sole plate is rotated by a load applied at the time of landing
the sole plate so as to set its bottom surface parallel to the ground, and when the sole plate is lifted, a size of the rotational
load is set so as to maintain the sole plate and the leg protective plate in states immediately before the lifting.
