The inner circumferential face of the accommodation unit has a second gear area provided with a second gear, a second tube area that pinches and closes the tube, and a protruding area with a protruding part formed about the axis. The pair of roller units rotate about the axis with the protruding part accommodated in the groove. The tip of the protruding part is arranged at a position more projecting toward the axis than the second gear.
