A pushcart includes a steering unit, a main wheel, a dolly portion, an auxiliary wheel, a connecting unit, a slope angle sensor, a gyrosensor, and a case. On one end of the steering unit, there is provided a cylinder-shaped hinge unit that is supported in a rotatable manner at the other end of the connecting unit on the opposite side to the main wheels, and a holding portion is provided on the other end of the steering unit. A controller performs inverted pendulum control in which the main wheels are rotated based on the detection results of the gyrosensor and the slope angle sensor.
