Claims

[Scope of utility model registration request]

An axle disposed on the vehicle body, a pair of left and right driving wheels respectively disposed on this axle, a pair of motors that can freely rotate in forward and reverse directions and that are disposed corresponding to these pair of driving wheels, and these pairs of motors. a pair of drive gears that transmit rotation to each of the driving wheels; a fixed shaft that commonly supports the pair of drive gears so as to be rotatable and movable in the axial direction; and a clutch that connects and separates both drive gears by moving them toward and away from each other. A traveling mechanism characterized in that the side motor rotates in the opposite direction, the two drive gears rotate at the same speed by being integrally connected by the dog clutch when moving forward, and the clutch is released when turning.
