Abstract:
PROBLEM TO BE SOLVED: To provide a mounting structure of a valve unit in which work such as maintenance is easy and which has no risk of gas leakage.SOLUTION: A mounting protrusion part is provided in a joint pipe which is provided outside of an exterior case and to which a gas main pipe is connected, and the mounting protrusion part is made to protrude to the inside of the exterior case from a through-hole provided at the exterior case. Then, the mounting protrusion part is screwed to a screw fixing part of a valve unit. In this way, the valve unit can be easily mounted while visually recognizing the mounting protrusion part of the joint pipe and the screw fixing part of the valve unit from the inside of the exterior case. Also, the mounting protrusion part of the joint pipe and the screw fixing part of the valve unit can be screwed firmly, so that there is no risk of a fuel gas leaking from a seam part between the joint pipe and the valve unit.
