A refill unit that includes a case, a door, a locking member and an unlocking member. The locking member slides between a protruded position and a retracted position and is engageable with the case at an intermediate position between the protruded position and the retracted position to lock the door in a closed position. the locking member is displaced toward the retracted position to release the engagement. The unlocking member is turnably supported on the door and is capable of moving, when the door is in the closed position, between a neutral position and a housed position. The unlocking member is displaced from the neutral position to a fallen position to displace the locking member from the intermediate position to the retracted position.
