Abstract
In a frictional drive vehicle, a load acting on the vehicle such as the weight of a rider is converted into a force that urges two frictionally engaging parts (L,R,) toward each other. Thereby, the contact pressure between the two frictionally engaging parts is maintained at an optimum level under all conditions. A weight of a rider may be transmitted to a drive member that frictionally engages a main wheel via a four-link parallel link mechanism ().
