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.

Abstract: The present invention discloses a winch and an autonomous mobile apparatus including the winch. The winch can include: a driving motor; a driving axle configured to rotate by having a driving force transferred from the driving motor; a wire drum installed on the driving axle in such a way that the wire drum is rotated by the driving axle and can move along the driving axle, a first screw part formed on an external circumferential surface of lengthwise end thereof; and a guide part arranged to be parallel to the driving axle and having a second screw part formed on a lateral side that faces the driving axle, the second screw part being extended in a lengthwise direction of the driving axle and engaged with the first screw part. The wire drum can move along the guide part in such a way that the length of a wire being wound or unwound for one rotation of the wire drum is constant.
