Abstract
A walking assisting device having leg links connected to a load transfer portion, wherein each leg link is free to bend and stretch at a joint in the middle of the leg link, the leg link being formed to a length such that the joint projects forward of a reference line when a user is standing upright. The reference line is a line connecting a swing fulcrum of the leg link to a joint at the lower end of the leg link. Stability is improved by diminishing a moment in a forward tilting direction when the user is standing upright. The leg links are provided with an overhanging portion and a driving source mounted on the overhanging portion, which helps maintain balance relative to the reference line. The driving force is transmitted to the joint in the middle of the leg link via driving force transmission means.
