A double-layer vacuum container includes: an inner container having a bridging member supported by an outer container in a bridging manner; the outer container through which the bridging member extending from the inner container is externally exposed; and a cover member for externally covering the portion of the outer container through which the bridging member is exposed and for sealing a space inside the cover member and a space between the inner container and the outer container in a vacuum state between the cover member and the outer container. With such a structure of the double-layer vacuum container, the inner container other than a lip is supported by the outer container with a good heat retaining property to prevent the displacement or damage of the inner container.

A heat storage tank includes a tank body having a cylindrical opening portion at one end side, and a coolant passage portion for defining therein flow passages communicating with the tank body. The tank body stores a coolant of a liquid-cooled engine therein while being thermal insulated, and the coolant flows into and flows out of the tank body through the flow passages. The coolant passage portion includes an insertion portion that is inserted into the opening portion in its axial direction. At least two O-rings are provided between the opening portion of the tank body and the insertion portion to seal a clearance therebetween, and are lined in the axial direction to be separated from each other in the axial direction by a predetermined distance. Accordingly, the heat storage tank can improve sealing performance of the coolant.

In the inventive heat storage tank, the welded portionbetween the inner tankand the outer tankis not encircled by the housingbut opens outward in the radial direction of the tank body port, and a gapis provided in the axial direction of the tank body portbetween the welded portionand a par of the housingopposed to the welded portionin the axial direction of the tank body port. Also, there is an elastic memberbetween the peripheryof the pipe-inserting holein the flow-straightening memberand the flange
