Abstract
Heat generated by a drive source of a friction drive device such as an electric motor is allowed to efficiently dissipate to the atmosphere, and the friction drive device and an omni-directional vehicle using the same is designed in a highly compact manner. Left and right electric drive devices are placed on a central axial line of left and right rotatable drive members, and external teeth members serving as output members of the electric drive devices are directly connected to the respective rotatable drive members in a torque transmitting and heat transmitting relationship.
