The wheelchair also comprises a right and left inclination-detecting rotary encoder 4, and a front and rear inclination-detecting rotary encoder 6, which are pivotally arranged in the body part 2 so that the chair part 1 can be rotated back and forth by a rotary shaft 13 arranged in the front and rear direction of the wheelchair and right and left by a rotary shaft 14 arranged in the right and left direction. The wheelchair is also provided with a right and left direction rocking actuator 5, and a front and rear direction rocking actuator 7, with which an angle made between the chair part 1 and the body part 2 is adjusted in accordance with the outputs of the rotary encoders 4, 6.
