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. 【課題】メンテナンスなどの作業が容易で、ガス漏れの虞のないバルブユニットの取付構造を提供する。【解決手段】外装ケースの外側に設けられてガス元管が接続されるジョイント管に取付凸部を設けておき、この取付凸部を、外装ケースに設けた貫通穴から外装ケースの内側に突出させる。そして、この取付凸部をバルブユニットのネジ止部にネジ止めする。こうすれば、ジョイント管の取付凸部と、バルブユニットのネジ止部とを、外装ケースの内側から視認しながら、バルブユニットを容易に取り付けることができる。また、ジョイント管の取付凸部とバルブユニットのネジ止部とは、しっかりとネジ止めすることができるので、ジョイント管とバルブユニットとの繋ぎ目部分から燃料ガスが洩れる虞もない。【選択図】図３
