This paper describes the representation of an assembly architecture. A functional element is introduced to represent assembly architecture. By using this functional element, constraint of assembly architecture can be naturally described. This functional element is used to express relations among the parts. The constraint among assembly parts which interfere without touching can be described by the relation. The relation has an assembly method etc. and can describe constraint and interference. It is shown that the search space of the assembly sequence is reduced by using our representation of assembly architecture.
