In these years, increase of wastes and exhaust of resource become major issues according to the progress of mass productive, mass consumptive and mass waste economic system. As the correspondence, the construction of the sustainable society is strongly required. For constructing such society, the consideration to 3R (Reduce, Reuse, Recycle) at the design stage of industrial products become very important. Especially, as concerns Reuse and Recycle, the improvement of disassembling property of the products is one of the most important things to be considered. In this study, we attempted to investigate Disassembly-Oriented Design (DOD) for wheelchair, of which demand is estimated to increase due to the arrival of the aging society, by disassembling them. By disassembling them we understood the problems of the structure and compared the disassembling property of these products by applying the method of estimating products' disassembling property. Then we got the guide about DOD for wheelchair. In addition, by achieving DOD, the alternation of design in accordance with Time Place and Occasion (TPO), like ceremonial occasions, is considered to become easily at the using stage. In this paper, we also proposed the new concept of wheelchair which took both environment and welfare into consideration.
