In the former report, the mechanism of rolling contact was discussed and the distribution of force, stress, stain and the sliding velocity in the contact area, as well as the relation between the driving force and the rolling friction, were obtained, on the assumption that the sliding friction coefficient does not depend on the sliding velocity (Coulomb's friction law). But in the case of rolling, there arises very low sliding velocity in the contact area, so the friction law does not always follow Coulomb's law, but rather depends on the state of the surface of contact. So in this report, the problems of tolling contact are discussed for general case. For example, a certain form of friction coefficient beins assumed, the relation between the driving force and the slipping ratio, which is equall to the ratio of loss of energy, is calculated and it is in good agreement with Sachs' experiment. Also the distribution of force, stress and strain in the contact area are obtained. In the last section, the relation between the motion of a wheel and the side force is discussed.
