Many cases are reused and only the case or part of the case is made new. Therefore, the power unit has a vertical engine and a gear transmission connected to the side of the crankcase in an abbreviated shape similar to a motorcycle, and the crankshaft is connected in the left-right direction of the vehicle. The vehicle is mounted so that it faces toward the vehicle, and the running wheels are driven via a chain.

7h%OI5 yj@VC″11″182) is housed in an integrated case, and the power unit 6t is arranged in an approximately triangular shape, with the crankshaft oriented in the direction of vehicle travel in the center of the nine-body frame. Since it can be easily mounted on a motorcycle, it is easy to adopt a configuration in which the front and rear wheels are driven by the shaft using the power unit of a conventional motorcycle. Further, when mounting the power unit on the vehicle body frame 1, the crankshaft 9 of the engine is directed in the traveling direction of the vehicle, and the ratio transmission 8 is protruded to the side.
Since the engine is passed under the upper member 1b and supported by the lower member 1a on the other side via the bracket 1g, it is easy to assemble it into the vehicle body frame 2, even though the engine itself has an approximately rectangular side shape. However, it has the advantage of providing a relatively lightweight and highly rigid body frame structure.
