A cartridge case (3) includes a case (33), a spout support portion (37), a mount opening (339), a roll-up member (43), and a resistance portion (479E). The case includes a first inner face (344) extending in a first direction. The spout support portion is provided on a first direction end portion end of the case and supports a spout (7) provided in an liquid container (31). An end portion at the first direction end of an elastic member (45) is mounted in the mount opening. The roll-up member rolls up the liquid container by being moved in the first direction by an energizing force of the elastic member. The resistance portion generates resistance to the movement of the roll-up member in the first direction at the first direction end portion end of the case. The resistance increases as the roll-up member moves in the first direction. |
