抄録

In the upward work, the workers need to keep the upper limbs with their own muscular strength and the work burden is large. The authors developed a supporting device using a self-weight compensation mechanism to reduce the burden on the upper limbs during upward work. However, there were wearers who felt strange about the wearing feeling, because there was not designed according to the physique of the wearer. In this study, we had the subjects of various physique wear the device, and investigated the relationship between the physique and the wearing feeling at shoulder joint movements. As a result, the subjects with greater shoulder width felt difficulty moving and small in size in the movement in the direction of ir/er. The influence on the ease of motion and size feeling was small in direction of flex/ext and add/abd.
