になった。In the present invention, the left and right axles for driving the left and right driving ground bodies separately are arranged on the same axis, and a constantly rotating gear is arranged with an axis parallel to the axle, and each of the axle gears provided on the axle is arranged on the same axis. In contrast, steering gears that mesh with each other on the radial outer circumference are linked to rotate in the same direction with the constantly rotating gear, and the left and right axles are connected to the constantly rotating gear via the steering gear. At the same time, each of the steering gears is separately displaced in a direction parallel to the axis of the axle so that the connection between the constantly rotating gear and the axle can be individually disconnected and disconnected, and the axial length is adjusted to the above-described length. A reversing gear is configured to be shorter than the spacing length between both axle gears, and is movable along the axial direction of the axle, and is displaceable along the axial direction of the axle. It is characterized by a structure that allows the gears to be displaced between a position where they selectively mesh with each other on the radial outer circumference and a position where they do not mesh with both, and therefore it is different from the conventional left and right axles and constantly rotating gears. With an extremely simple configuration that only requires one reversing gear to be added to the steering mission that links each separately,
In addition to being used for interlining rotation, the gear-driven mission is also used to rotate the interlining, and simply by shifting the reversing gear to a position where it does not mesh with both axle gears, no driving force is transmitted to either the left or right axle gears. The interlining rotation state can now be canceled easily.
