SOLUTION: The heat accumulator has a double structure comprising an inner tank and an outer tank, between which a vacuum space is formed. The inner and outer tanks have respective openings, which are joined to each other along their circumference, and are provided with a means for suppressing the vibration of the inner tank. Both tanks are kept separated, except the joined part, at least while a vehicle stops. COPYRIGHT: (C)2004,JPO
