A gas filtering device includes a housing (), a flexible filter sheet (), an inlet port (), an outlet port (), and a displacement restriction portion () is provided. The flexible filter sheet () divides the interior of the housing into an inlet chamber and an outlet chamber. The filter sheet () has a portion that allows passage of gas. The inlet port is connected to the inlet chamber, and conducts gas into the inlet chamber. The outlet port is connected to the outlet chamber, and conducts gas from the inlet chamber to the/outlet chamber through the filter sheet. The outlet port has an opening close to the gas passing portion of the filter sheet. The displacement restricting portion () restricts displacement of the gas passing portion toward the opening.

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 ignition system includes an ignition coil which provides ignition voltage of one polarity, an igniter which supplies the primary current to the ignition coil at regular timings and a zener diode connected in series with the primary coil of the ignition coil. The zener diode shares a constant voltage drop of the opposite polarity at the secondary coil of the ignition coil, thereby reducing troublesome voltage induced in said secondary coil other than at regular ignition timings. On the other hand, the zener diode does not share the voltage drop of the ignition voltage at the regular timings, and thus no energy loss is incurred.
