A crawler vehicle has a pair or several wheels wrapped around it on both sides of the main body of the vehicle, and rotates the wheels to press the crawlers against the road surface while traveling. When changing the direction of movement, this is done by making a difference in the speed of the left and right crawler tracks, or by reversing the speed. Generally, the contact distance of the crawler track is long, so during steering, most of the contact surface of the track slides sideways, consuming a large amount of energy due to friction with the road surface. For this reason, in order to reduce the ground contact area of the crawler belt and make it easier to change direction, a configuration has been proposed in which the wheels in contact with the back surface of the crawler belt are pushed down, as shown in Japanese Patent Laid-Open No. 154940/1983.

押下げて履帯の一部を下方に突出させるが、その
転輪の押下げ機構はそれ専用の駆動装置を設置し

問題点があつた。
In the above conventional technology, in order to obtain low ground contact pressure, a part of the crawler track is pushed down by pushing down the track wheel, but since the push-down mechanism for the track wheel is equipped with a dedicated drive device, it is difficult to move. There was a problem with the overall weight of the car.

とができるクローラ走行車のステアリング装置を
提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a steering device for a crawler vehicle that can reduce the weight of the crawler vehicle and save energy consumption.

The above-mentioned object of the present invention is to provide a vehicle body, two rotatable wheels provided on both front and rear sides of the vehicle body, a wheel mounted on an arm rotatably provided in the center of a side surface of the vehicle body, and a wheel mounted on an arm rotatably provided at the center of a side surface of the vehicle body. In a crawler vehicle comprising a crawler track wrapped around the vehicle body and a driving means for rotating at least one of the wheels provided on the vehicle body, a part of the crawler track is pushed down or a part of the vehicle body is pushed down at the base of the arm. This is achieved by integrally providing a lever body for lifting.

By rotating the arm, the lever body integrally provided at the base of the arm pushes down a part of the track or lifts the vehicle body, thereby reducing the contact length of the track and also increasing the length of the track. Since the load is concentrated only on one part, steering becomes easier.
Moreover, since the movement is possible only by turning the arm, there is less energy loss and the weight of the vehicle body can be reduced.
