This paper presents a relative evaluation method from a viewpoint of straight mobility of wheelchairs depending on the hardness of floors and pavements. The first, the sensory scales indicating the mobility were made by sensory test with various floors and wheelchairs. The second, pulling loads of wheelchairs were measured in experiments. As a result, the pulling loads were presented as a evalutaion index for corresponding to sensory scales. Finally, it was presented that pulling loads of various wheelchairs could be estimated by that of Standard Caster and the specifications (size, weight, etc.) of each wheelchairs.
