The stopper is provided in the port and urged outward to close the port. The joint section is provided in a printer and coupled with the port. The joint section has an ink flow path that communicates with the port while the port is coupled. The insertion rod is provided in the joint section for pushing the stopper inward to communicate the ink flow path with the port while the port is coupled. The anti-outflow member is slidably provided in the joint section. The anti-outflow member is urged outward and slides along the insertion rod when the port is being inserted into the joint section.
