<p>A pressurized reservoir tank (TA) has outer peripheral walls (1a, 2a) capable of closing the inside of the tank in which liquid (CL) is contained; substantially circular tube-like center walls (3, 7) placed at the center inside the outer peripheral walls (1a, 2a) and forming center chambers (5a, 9a); and partition walls (4a-4d, 8a-8d) extending in a radial pattern from the center walls (3, 7) toward the outer peripheral walls (1a, 2a) and partitioning outer peripheral chambers (5b-5e, 9b-9e) that are placed around the center chambers (5a, 9a), between the center walls (3, 7) and the outer peripheral walls (1a, 2a). The center walls (3, 7) have slits (6a-6d, 10a-10d) for communicating with each other, respectively, the center chambers (5a, 9a) and the outer peripheral chambers (5b-5e, 9b-9e).</p> |
