The front and rear wheels 8, 7 can be driven, and a steering wheel speed increasing device 59 that can change the speed ratio is interposed between the final drive device 56 of the front wheels 8 and the front propeller shaft 55, so that the steering can be performed. The speed increasing device 59 is operated by the speed ratio switching mechanism 69 which is interlocked with the means 10.
In a vehicle configured to be able to switch from a constant speed operating state to an increased speed operating state, sensors 24 and 25 for detecting the tilt angle of the aircraft body are disposed on the aircraft body,
The steering wheel speed increasing device 59 is configured to forcibly switch the steering wheel speed increasing device 59 to a constant speed operating state when the tilt angle detected by the sensors 24 and 25 becomes larger than a preset angle. Speed ratio switching control device for speed equipment.
