BACKGROUND ART Conventionally, motorized four-wheeled vehicles that are steered using a rod-shaped steering handle are known. Furthermore, in a general four-wheel vehicle, in a four-wheel drive vehicle that drives all wheels, it is also known that the transmission shaft from the engine to the drive shaft is arranged to face the direction of travel of the vehicle (Japanese Patent Laid-Open Publication No. 57-164815). However, when trying to use this on rough terrain, the overall width of the vehicle becomes wider, which limits the driver's weight movement on the vehicle, and although this does not pose any problem on the road, it becomes a constraint on free driving on rough terrain. There is.

As described above, the four-wheeled motor vehicle of the present invention has a steering shaft tube above the front of the body frame, a down tube extending downward from the steering shaft tube and supporting the front end of the power unit, and a down tube extending rearward. Since it is constructed with a main pillar that supports the rear end of the power unit, the highest part of the engine can be placed directly below the main pillar 4c that makes up the vehicle body frame 4, and even when the power unit is tall, It can be installed relatively easily.
