An electric wheel chair 1 comprises: a vehicle body 2a; casters 2c and main wheels 2b; a drive wheel 14c disposed between the casters 2c and the main wheels 2b; a pair of motors 15; a current detecting unit 36 that detects the motor current; a sensor 8 that detects an inclination angle of the vehicle body 2a; a first operating unit 10 that has a grip 20 which can move in the front-back direction of the vehicle body 2a, and a potentiometer 21 that detects the displacement amount of the grip 20 in the front-back direction; and a control device 18 that controls the pair of motors 15. The control device 18 comprises a processing unit 38 that executes: a first comparison process 38c for comparing the motor current and a current threshold Ith that is the motor current in a low-load state; a second comparison process 38d for comparing an inclination angle θ and an angle threshold θth; and a first switching process 38e for switching the control mode of the motors 15 from a normal mode to a stop mode on the basis of the comparison result of the first comparison process 38c and the comparison result of the second comparison process 38d.
