Claims

[Scope of 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 wheel 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 handle to a master cylinder of a hydraulic circuit that operates the clutch device or the brake device includes a cam rotatable in conjunction with the handle; 1. A crawler belt type vehicle, characterized in that it is provided with an engaging and swingable lever, and the lever is connected to an actuating rod of the master cylinder.
