Claims

[Scope of utility model registration request]

The front and rear axle cases 45 and 64, which support the front and rear axles 32 and 60, are rotated and rotated around an intermediate shaft 39 and a rear wheel drive shaft 55, which are interlocked and connected to the respective shafts 32 and 60 and are supported on the body side. The front wheel drive disconnection mechanism M1, the front wheel brake mechanism M2, the rear wheel drive disconnection mechanism M3, and the rear wheel brake mechanism M are configured to be fixed freely.
4. In a vehicle that is provided with a rear axle case fixing mechanism M5, and allows the vehicle height to be changed by braking one of the front and rear wheels 7, 5, driving the other, and rotating the axle case on the driven side. , each of the above mechanisms M1
, M2, M3, M4, and M5 are linked to a single vehicle body elevation control lever 103 through a shift mechanism M7 having three rows of left and right rows, an operating range of two front and rear positions for each row, and an operating position resolution. A vehicle body lifting/lowering operation lever structure for a vehicle that is connected and capable of changing vehicle height.
