We here investigated three dimensional motions of rigid bodies on a rigid floor under seismic excitations. Behavior of the rigid bodies is simple and familiar phenomena, but is very difficult and complicated problem from an analytical point of view. It is very important for earthquake disaster prevention to consider the behavior of such rigid bodies as equipments installed in the buildings and houses. Computer program that can calculate die behavior of the rigid bodies is developed to simulate the response under the seismic excitations. The motions of the rigid bodies are classified six types in a three dimensional space; rest, slide, rotation, slide rotation, translation jump and rotation jump. Transition of motion occurs among the six types. Equations of motion are constructed for six degree-of-freedom of translations and rotations.
