Abstract: A cartridge accommodates a clip unit including an arm member and a tubular housing, and is configured so that the clip unit is able to be mounted in an applicator having a sheath and an operation wire. The cartridge includes a main body in which an insertion hole into which the sheath is inserted is formed and a pusher configured to be movable with respect to the main body. The pusher is configured to come into contact with an engaging member provided in the sheath by moving the sheath with respect to the main body in a state in which the sheath is inserted into the insertion hole. The pusher is configured to push the engaging member against the housing, and to engage the sheath with the housing by engaging the engaging member with both the housing and the sheath.
