<p>A cover (100) includes side walls (121, 122, 123) provided upright around a reservoir (120) in which a liquid overflowing from a tap or port (310) of a tank (300) is retained, and a pent roof (124) is extended above the reservoir (120) from the side walls (121, 122, 123). Thereby, liquid retained in the reservoir (120) is also dammed up by the pent roof (124), so that the reservoir (120) is improved in volume.</p> |
