Abstract
A nonwoven fabric (31) having an annular shape in the horizontal cross-sectional view is put inside of a pressure-resistant wall (11) of a gas cylinder (2) adapted to contain liquefied petroleum gas (19). An outer surface (34) of the nonwoven fabric (31) is kept in contact with an upper portion of an inner surface (20) of the pressure-resistant wall (11). A lower section (33) of the nonwoven fabric (31) is adapted to suck up the liquefied petroleum gas (19) in its liquid phase portion (25) owing to capillary action, so that the sucked up liquefied gas can be brought into contact with the upper portion of the inner surface (20) of the pressure-resistant wall (11).
