There are several hypotheses on the mechanism of rolling friction, but they are not recognized as an established theory. Authors recently reported the experimental research on the high speed rolling friction and clarified the many characteristics which cannot be expounded by the former hypotheses. In this paper, the new hypothesis about the rolling frictions at every case of the start, low speed and high speed are presented. The rolling friction at start is attributed to the potential energy loss caused by the surface roughness and theorized considering the elastic deformation. The potential energy loss theory cannot be applied to the kinetic rolling friction, but the low speed rolling friction is due to the sliding friction caused by the meshing of contact surfaces and then the high speed rolling friction is resulted from the energy loss with the minute collisions occur on the dry surface and from the fluid friction on the lubricated surface.
