PURPOSE:To permit a device to perform the action of rapid turning when a vehicle is turned in the final end position of reaping, by providing a reversing transmission mechanism, which transmits rotation of each crawler device in a reverse direction to each other, and a clutch, which interrupts transmitting this reverse rotation, between the right and left pair of crawler devices. CONSTITUTION:A transmission case 12, having a pair of side clutches 1, 1 individually interrupting the transmitting action, is arranged between a pair of right and left driving shafts 11, 11 rotatably supported to the front end part of a truck 6. While a gear case 21 of a reversing transmission mechanism 3 is provided in the rear end part of a left side supporting lever 9, securing a driven sprocket 22, meshed with a crawler 15, to the end part of a transmission shaft 18 of said mechanism 3 while providing a sliding pawl member 23 of a clutch 4, sliding on an intermediate shaft 20, in its end part, and a clutch shaft 25, providing a pawl member 24 engageable with said pawl member 23, is supported to an extending part of the gear case 21. And when either the right or left side clutch 1 is controlled to a disengaging side, the clutch 4 can be controlled to an engaging side through a connecting rod 35.

BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION In a steering device for a mobile vehicle having left and right side clutches and left and right brakes that can individually disconnect and disconnect power transmission to a pair of left and right crawler devices, for example, When performing reciprocating reaping work with a combine harvester, etc., turning is performed by operating the side clutch and brake on the turning direction side at the cutting end position, but even if the crawler device on the turning direction side stops, a constant turning radius is required. With this constant turning radius, it is not easy to adjust the aircraft to the direction of the culm that will be harvested next.
In addition, when it is not possible to align with the row during a turn, the maneuvering operation becomes complicated and the time required for the turn becomes longer.
