Summary:An apparatus was constructed for direct observation of true contact area between two rollers in rolling contact. For this attempt, a glass roller having triangular cross section was newly prepared. The actual area of contact between the glass roller and a steel roller could be observed by an internal reflection method. With this apparatus, it was observed that the minor axis of the contact ellipse decreased with increase of the speed of revolution. We believe that if quantitative calculations were to follow these results, a more accurate analysis of rolling friction could be obtained.
