A pushcart includes a main body, a pair of main wheels, a supporter, an auxiliary wheel, a blocking unit, a switching lever, a slope angle sensor, a gyrosensor, a driver unit, and a supporter rotary encoder. The supporter rotary encoder detects an intersecting angle which is an angle formed by the main body and the supporter, and outputs the detected result to a controller. The gyrosensor detects an angular velocity of the main body in a pitch direction and outputs the detected result to the controller. The controller performs inverted pendulum control in a first control mode based on the detected results of the gyrosensor and the supporter rotary encoder. The controller performs inverted pendulum control in a second control mode based on the detected result of the gyrosensor
