In a variable intake apparatus for a V-type internal combustion engine, each of plural intake pipes is separated from a surge tank by a partition wall, and communication ports, provided in the partition wall for the respective intake pipes, are opened and closed by respective variable intake valves to adjust length of intake passages. The variable intake valves in one of two parallel rows are offset from the variable intake valves in the other row. The variable intake valves are opened and closed by turning the turning shafts to which the variable intake valves are connected. Further, a synchronization mechanism synchronously turns the turning shafts (), and is connected between the paired turning shafts. The turning motion of one turning shaft is transmitted to the other turning shaft via the synchronization mechanism, and the variable intake valves are synchronously opened and closed.

A mounting structure for a heat accumulation tank is provided with an elastic member that wraps around a tank main body, and a heat accumulation tank mounting member which wraps around the outer peripheral surface of the elastic member and holds the tank main body by being tightened in the circumferential direction, and which attaches to a receiving member. The elastic member is a molded part. The length of the elastic member is shorter than length of the circumference of the outer peripheral surface of the tank main body. The heat accumulation tank mounting member includes a shift inhibiting portion which inhibits an upward shift of the tank main body. The outside diameter of the tank main body becomes increasingly wider in the upward direction.

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.

An engine cooling apparatus has a heat storage tank for storing and maintaining the temperature of cooling liquid let out of an engine into an engine cooling circuit. The heat storage tank is mounted in a vehicle so that a housing retained to a lower portion of a tank body forms a lowermost end portion of the engine cooling circuit in a vertical direction. An inlet passage of the housing is provided with a drain port. A portion (drooped portion) of a cooling liquid channel upstream of the drain port is lower than the position of the drain port in the vertical direction.
