PROBLEM TO BE SOLVED: To provide a handcart which is not deteriorated in traveling performance.SOLUTION: A handcart 1 comprises: a body part 10; a main wheel 11 which is rotatably supported by the body part 10. The handcart 1 detects angular variation in a pitch direction of the body part 10, and on the basis of the detection result, the main wheel 11 is rotated, and rotation-control is performed to the main wheel 11 so that the angular variation of the body part 10 is 0. In an advancing direction side of the body part 10, there is provided a support part 12 which prohibits the body part 10 from tilting more than a designated angle in the advancing direction side. The handcart 1 restricts angular variation in a pitch direction of the support part 12, and also releases the restriction.SELECTED DRAWING: Figure 5 |
