Abstract
In this research, it proposed the active installation device that additionally fixed a wearable equipment to installation person's movement appropriately and handily, and it proposed a simple holding power control valve that controlled it. It was possible to correspond to a dynamic thickness change in the applied part by the holding power and length's changing by air power, and it aimed at the achievement of a handy installation device. It proposed the structure to roll when pressurizing it and to fix the installation device that used the flat tube. Next, it proposed a light and simple holding power control valve by flat tube to achieve an appropriate holding power control with a proposed installation device
