This paper presents the relationship between the caster vibration and the configuration of real floors that have regular and continuous unevenness from the viewpoint of trouble to humans. First, we measured the vibration of the special caster and a wheelchair, and showed the correlation. Next, we carried out sensory tests about feeling during movement. Consequently, we showed that feeling during movement is influenced by vertical acceleration. Finally, we determined the factors that affect vertical acceleration and feeling during movement. They were influenced by the width of the joint and the edge width of each floor material.
