Abstract
A walking assistance device having a leg link connected to a load transmit portion via a first joint and to a foot attachment portion via a second joint, and having an intermediate third joint moving such that a distance between the first joint and the second joint is variable; a drive source for the third joint; and a battery for the drive source. When in an upstanding position, force in the forward-backward direction is prevented from acting on the load transmit portion to enhance stability. Also, a moment of inertia of the leg link is decreased to curtail a load applied to the leg of the user. The drive source and the battery are located at positions higher than the third joint, and when the user is in an upstanding position, a plane passing through the second joint lies between the drive source and the battery.
