In recent years, many devices developed to assist walking accompanied the aging society are spreading. However, the walking assist device using the controller makes the users dependent on the device and may hinder the subjective actions. The development of an inexpensive device with a simple structure and less risk of accidents is expected. And it is also necessary to make a proper walking not to decrease the range of joints and muscles. The purpose of this research is to develop a device which reproduces the functional relationship between angular displacements of the hip joint and knee joint of part of swing phase and stance phase without using a controller and to lead a location of ankle joint. It is also expected to assist hip joint and knee joint each other using own weight. The device’s motion is based on kinematic constants that reproduce the functional relationship between angular displacements of the hip joint and knee joint. These results are checked by a method measurement with motion sensors and torque converter. In result, the device reproduced the functional relationship between angular displacements of the hip joint and knee joint mostly as it is expected, and the torque ratio of input torque to output torque shows possibility of mutual assistance between hip joint and knee joint.
