We propose a simple method of measurement of rolling friction coefficients of individual casters and rear wheels of wheelchairs on the surrounding surfaces. We used a slope to measure the running distance from the bottom edge of the slope under free falling conditions. The rolling friction coefficients in this method were similar to using the force plate within casters and rear wheels of wheelchairs. Then by using the method proposed, we can calculate the rolling friction coefficients of them on the surrounding surfaces. For example, we measured the friction coefficients of the deck of the Training Ship KOJIMA of Japan Coast Guard Academy, the floors (vinyl sheet) of laboratories, sidewalks made of asphalt, block and sand. These data are necessary to analyze the running characteristic of wheelchairs by the simulation model.
