Provided is a tool for aiding ambulatory movement which is used by persons having a diminished walking capacity and is based on a novel technical concept focusing on the swinging leg. The tool supports walking motion with little force so as to promote a walking motion resulting from the actual muscle strength of the person having a diminished walking capacity and increase walking speed, thereby making it possible to effectively suppress a decline in muscle strength while also increasing the walking time and walking distance with less energy if a constant walking speed is maintained. A tool (10) for aiding the ambulatory swing movement of the swinging leg is provided with, as a pair for the left and right legs, assist members to which are provided drive sources (40) for exerting a pull force on an auxiliary force transmission section (12), the tool (10) also having: joint angle sensors (32) for detecting the joint angles in the user's hip joints; and a control means (50) for aiding pendulum movement of the swinging leg by controlling the drive of each of the drive sources (40) in each of the assist members in response to changes in the joint angles, and exerting an assist force in the forward swing-out direction with respect to the swinging leg that has pushed off from the ground.L'invention concerne un outil pour assister un mouvement ambulatoire, qui est utilisé par des personnes ayant une capacité de marche réduite et est basé sur un nouveau concept technique se concentrant sur la jambe libre. L'outil supporte un mouvement de marche avec peu de force de façon à favoriser un mouvement de marche résultant de la force musculaire réelle de la personne ayant une capacité de marche réduite et à augmenter la vitesse de marche, permettant ainsi de supprimer efficacement un déclin de la force musculaire tout en augmentant également le temps de marche et la distance de marche avec moins d'énergie si une vitesse de marche constante est maintenue.
