This paper describes the equipment to evaluate human capacity of fall avoidance in seated position. The equipment makes a subject fall safely by supporting the upper body by wire parallel mechanism. Therefore, the equipment makes it possible to obtain the evaluation data of capacity of fall avoidance at the moment when the subject falls. The mechanism consists of four wires connecting a base chair to an output link attached to the thorax so as to support and control 3DOF motion of the upper body. Force sensors were attached to the wires which detect the time when the subjects fall and force-plate were set on base chair to measure the center of pressure (COP) which is generally used for the evaluation. The experimental result for the subject confirmed that the equipment measured the evaluation data of falls avoidance, such as variances of COP or moment around axes of a 3DOF joint of the equipment, at the time when the subject became unstable.
