- a pump body having a base to and from which the tube can be attached and detached;
a door pivotally supported to be rotatable with respect to the pump body within a rotation range between a completely-closed position where the base is covered and a completely-opened position where the base is uncovered, the rotation range including a first rotation range and a second rotation range, the first rotation range being located at a completely opened position side of the second rotation range and the second rotation range being located at a completely closed position side of the first rotation range;
a rotation base provided on one end of the door;
a switching urging unit having a first urging member and a portion configured to press the rotation base due to an urging force of the first urging member to urge the door in an opening direction in the first rotation range and to switch an urging direction to a closing direction in the second rotation range; and
a closing suppression unit having a second urging member to suppress the urging force of the first urging member in the closing direction by the switching urging unit in the second rotation range, whereinthe second rotation range includes a first specified range and a second specified range, the first specified range being located on a completely-opened position side of the second specified range, the second specified range being located on a completely-closed position side of the first specified range, andthe closing suppression unit is provided not to suppress the urging force in the closing direction by the switching urging unit in the first specified range but to suppress the urging force in the closing direction by the switching urging unit in the second specified range.
