Claims

[Scope of Claim for Utility Model Registration] (1) A crawler in which a covering belt is stretched around guide wheels and drive wheels arranged at both front and rear ends of a vehicle body frame, and the lower middle part of the covering belt is supported by a lower roller. A crawler vehicle, characterized in that the guide wheel, the driving wheel, and the lower roller are supported so as to be movable relative to each other in the vertical direction, so that only the lower roller support portion of the cover can be brought into contact with the ground. (2) In a crawler vehicle in which a covering belt is stretched around the guiding wheels and driving wheels arranged at both front and rear ends of the vehicle body frame, and the lower middle part of the covering belt is supported by lower rollers, the guiding wheels and the driving wheels are A crawler vehicle characterized in that the ground contact length of the covering belt can be changed by changing the interval between the wheels.
