A stair climbing vehicle that is able to stably climb stairs is provided. In order to keep the balance of the stair climbing vehicle at the time of climbing the stairs, the ratio between a gravity center moving control gain for the stair climbing vehicle and a turning control gain for first wheels and second wheels is changed by controlling the rotation of a first motor of each first turning actuator. Thus, it is possible to slightly turn the first wheels and the second wheels based on the posture of an occupant seated on the stair climbing vehicle when the occupant climbs the stairs with the stair climbing vehicle, thereby preventing the posture of the occupant from being unstable. Thus, the stair climbing vehicle is able to stably climb the stairs.
