PROBLEM TO BE SOLVED: To provide a membrane type gas meter that permits easy fitting of valves in a distribution chamber and more rapid assembling work.SOLUTION: A pair of rotation supporting shafts inserted through a pair of guide insertion holes in a distribution chamber to be fitted into fitting through-holes, formed at the base end of each of a pair of valves, are provided with valve guide members erected at the two end parts of a substantially rectangular parallelepiped shaped body part and substantially planar-shaped retaining plates, each fitted to the tip part of each of the pair of rotation supporting shafts, and the distribution chamber is so formed as to become depressed from the lower end face toward the upper end face to form an accommodating concave to accommodate the distribution chamber when the pair of rotation supporting shafts are inserted into the pair of guide insertion holes.SELECTED DRAWING: Figure 3 【課題】分配室にバルブを容易に取り付けることができ、組み立て作業の迅速化を図ることができる膜式ガスメータを提供する。【解決手段】分配室の一対のガイド挿通孔に挿通されて、一対のバルブのそれぞれの基端部に形成された取付用貫通孔に嵌入される一対の回動支持軸が、略直方体状の本体部の両端部に立設されたバルブガイド部材と、長手方向両端部が前記一対の回動支持軸の各先端部に取り付けられる略平板状の抜け止めプレートと、を備え、前記分配室は、下端面から上面側へ窪むように形成されて、前記一対の回動支持軸を前記一対のガイド挿通孔に挿通した場合に、前記本体部を該分配室内に収納する収納凹部を有するように構成する。【選択図】図３
