In this paper, the behavior of regular prisms rolling on a plane is investigated theoretically under the following conditions; (1) both the prism and the plane are rigid, (2) the sliding between the prism and the plane does not occur, (3) the collision between them is of plastic nature and the elastic rebound does not occur. Thus the rolling-friction coefficient of regular prism is defined, and that of cylindrical roller is induced, of which various properties are discussed. The results obtained from the calculations are as follows: (1) the static friction coefficient is larger than the kinetic one in the region where the rolling velocity is small, but the latter increases with the increase of velocity, (2) the friction due to collision between prism and plane is so small when the prism has a large number of sides, that it does not play an important part in conditions above mentioned, etc.
