Abstract
In order to achieve a walking assistance device that can be securely fitted to the user's body while allowing a certain degree of freedom, a walking assistance device is provided comprising a hip joint rotational force generator (hip joint actuator) mounted on a side of a hip joint and a knee joint rotational force generator (knee joint actuator) mounted on a side of a knee joint to provide an assisting force to a movement of a lower limb, wherein the hip joint rotational force generator is fitted to the body via a first linkage means (link plate) having at least two degrees of freedom, and wherein the hip joint rotational force generator and the knee joint rotational force generator are connected to each other via a second linkage means (link bar) having an expandable and contractable means. In this way, deformation in lateral and torsional directions of the first linkage means and expansion/contraction of the second linkage means can absorb a deviation in position between the joints of the user's body and the assisting force generators.
