Abstract
A walking assistance device () has a receiving portion () which receives a part of the weight of a user (A) applied from above and a pair of left and right leg links (R,L) connected to the receiving portion () through first joints (R,L), with foot attachment portions (R,L) at lower ends of the leg links (R,L) attached to the feet of the legs of the user (A), respectively. The leg links (R,L) are connected to the receiving portion () in such a way that, when each leg of the user (A) is a standing leg, a line of action of a supporting force transmitted from a third joint (R,L) of the leg link (R,L) to a crus frame (R,L) out of the supporting force acting on the leg link (R,L) from the floor side passes through a specific point (P) located upper than the receiving portion () within an anteroposterior width of a contact surface between the receiving portion () and the user (A) from the third joint (R,L), viewed in the sagittal plane. Thereby, it is possible to stably apply a desired lifting force for reducing the weight to be borne by the user with his/her legs to the user.
