Amendment October 16, 1982 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] In a traveling vehicle that has a pair of axles with wheels on both sides connected to a frame and has a reversible wheel rotation drive device, each axle is rotatably connected near the wheels. Each pair of support members is connected to the frame side so as to be rotatable back and forth, and the front pair of support rods and the rear pair of support rods are respectively inclined inward and arranged opposite each other, and a stopper is connected to each support rod. A stopper mechanism is provided which prevents the back and forth rotation of one pair of support rods, and a stopper mechanism which opens the one pair of support rods and prevents the other pair of support rods from back and forth rotation with the stopper. A vehicle for running between furrows, which is equipped with a switching mechanism, and is characterized in that the front and rear axles are connected to the frame side by rods in a state in which the wheels on both sides can move up and down at the center of each axle.

Claims (1)

[Scope of utility model registration request] In a traveling vehicle that has an axle with wheels on both sides under the frame at the front and rear and a reversible rotation drive device for the wheels, a pair of supporting members each of which each axle is rotatably connected near the wheel is attached to the front and rear. It is rotatably connected to the frame side, and has a front pair of support rods and a rear pair of support rods that are inclined inward and are arranged facing each other, and has a stopper connected to each support rod to support one pair. A stopper mechanism for preventing the longitudinal rotation of the rods is provided, and a stopper switching mechanism is provided for opening one of the pair of support rods and using the stopper to prevent the other pair of support rods from rotating back and forth. A traveling vehicle for a furrow passageway, characterized in that the wheels on both sides of the vehicle are connected to the frame side by rods in a state in which the wheels on both sides can move up and down at the center of the vehicle.
