る。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.

する。Means for Solving the Problems The present invention provides a pair of left and right crawler systems having side clutches (1) (1) that can separately connect and disconnect transmission from a travel transmission mechanism. (2) Between these left and right crawler devices (2) (2), there is a reverse transmission mechanism (3) that transmits rotation in opposite directions to each other, and a clutch (3) that connects and disconnects this reverse rotation.
4), and between this clutch (4) and the side clutches (1) (1), it is possible to operate one of the left and right side clutches (1) (1) to the disengaged side. A steering device for a moving vehicle is provided with a coupling mechanism (5) that can bring the clutch (4) to the input side.
