To achieve steering with a feeling where passengers drive a vehicle with their own leg force, facilitate the move to a desired location, and improve the effect for function recovery training, by calculating the rotary angle and rotary speed of a drive wheel based on the detection signal of a pedal rotary angle detection sensor for controlling a drive means.

A pedal 7 is provided at the position of the front end part of a machine body frame where passengers can steps the pedal 7 with their leg force, and a rotary angle detection sensor 15 for detecting the rotary angle of the pedal 7 is provided in the machine body frame. Also, a load-applying means 9 is further connected to the rotary part of the pedal 7 so that a load can be applied when the pedal 7 is to be rotated. More specifically, in the load-applying means 9, a friction plate is provided at the rotary part of the pedal 7 so that a load can be applied to the friction plate when the pedal 7 is to be rotated. Then, the load-applying means 9 is provided with an adjustment means 10 such as an adjustment knob, thus adjusting the size of the load when rotating the pedal 7 by adjusting force being applied to the friction plate according to the degree of functional recovery training.
