1. A cartridge comprising: a housing; a driving input member provided at the housing, the driving input member configured to be rotated by a driving force; a rotational member configured to receive the driving force, which is transmitted from the driving input member, and be rotated thereby; a detection protrusion including an elastic body and which is disposed at a position away from a rotational center of the rotational member, the detection protrusion protruding from the rotational member away from the housing; and a cover attached to the housing, the cover having an opposite part that faces a portion of the rotational member from which the detection protrusion protrudes, wherein, the rotational member is configured to be rotated between a first position and a second position, the first position being a position where the detection protrusion abuts the opposite part of the cover and is elastically deformed by the opposite part of the cover, the second position being a position where the detection protrusion is released from the cover and is not elastically deformed.
