Claims

[Claim for Utility Model Registration] At least one of the front and rear axles of a vehicle having at least four wheels is used as a drive shaft, the front and rear wheels are rotatably supported, and a crawler belt is arranged between the front and rear wheels. In crawler belt type vehicles, which have traveling devices on both the left and right sides of the vehicle body, a clutch device or a clutch device that can cut off the transmission of driving force to the inner wheels on the drive shaft side depending on the steering angle of the steering wheel. A brake device capable of stopping the rotation is provided, and a transmission mechanism connecting the clutch device or a master cylinder of a hydraulic circuit that operates the brake device and the handle is biased in the neutral direction in a small steering angle region, and in a large steering angle region. A crawler belt type vehicle characterized by being provided with spring means for biasing in the assist direction in the area.
