ABSTRACT:
A driving form switching apparatus enabling even a user of wheelchair who cannot freely use limb to easily change over a driving form by single hand self-operation. By using a differential gear mechanism or a combination mechanism comprising pinions and racks, the rotating, tilting and shifting motions of a steering lever are transmitted to two rotating shafts. Drums are directly coupled to the two rotating shafts, and the rotations of the two rotating shafts are transmitted to steering shafts through flexible wires as first connecting means. Also, the steering shafts for wheels are parallel- or cross-connected by second connecting means. Thus, the driving forms of a four-wheel drive vehicle such as back and forth traveling, counter-clockwise turning, clockwise turning, turning on the spot, parallel traveling, stopping and braking, etc, can be switched by a single-hand simple operation.
