PROBLEM TO BE SOLVED: To provide a lumbar burden alleviation tool which enables natural walking by releasing the tensile force of a tensile force transmission string automatically during upright walking and generates an auxiliary moment to the waist portion when the person restarts a forward-bending work after walking.SOLUTION: A lumbar burden alleviation tool (10) serves as a connectedly mounting mechanism (22) of a waist pad part (12b) and tensile force transmission strings (18, 20) and includes: a pair of right and left swing arms (22a, 22b) having an end rotationally pivoted on the waist pad part (12b) and the other end connected with the tensile force transmission strings (18, 20); springs (22e, 22f) connecting the other end of the swing arms (22a, 22b) and the waist pad part (12b); and stopper parts (22c, 22d) attached to the rotation arms (22a, 22b). |
