Abstract
The present invention discloses a winch and an autonomous mobile apparatus including the winch. The winch can include: a driving motor; a drum driving axle configured to be rotated the driving motor; a wire drum configured to be rotated by the drum driving axle; a roller driving axle arranged to be parallel to the drum driving axle and configured to be rotated in different direction from that of the drum driving axle by the driving motor; a roller connected with the roller driving axle and configured to support a wire wound on or unwound from the wire drum; and a one way clutch installed in the roller driving axle in such a way that a driving force transferred to the roller by the roller driving axle is cut off when the wire drum rotates in a direction of winding the wire. The roller can be transferred with a driving force by the roller driving axle and can be rotated in such a way that a wire placed between the wire drum and the roller maintains tension when the wire drum rotates in a direction of unwinding the wire.
