Claims (2)
- メーター本体(M)内には前後の計量室(4,5)を有し、各計量室を計量膜(6)で前後の部屋(7〜10)に仕切り、部屋へのガスの流入に伴って計量膜を往復動させ、計量膜の往復動を翼(12)の揺動運動に変換させるために、翼の先部の軸(14)に軸受(15)を係合し、計量膜を前後から挟んだ膜板(16)の中央部に軸受をネジ止めしてある膜式ガスメーターの計量膜用軸受止め構造において、
膜板には計量膜から離れるリブ(27)を同心円状に形成し、ネジ止め箇所を中心にして軸受が回転するのを規制する回り止め手段(21)を、軸受と膜板のリブに設け、
回り止め手段(21)が、凹部(19)と凸部(20)による嵌め合わせであって、膜板のリブと軸受の一方に凹部を、他方に凸部を設け、嵌り合った凹部及び凸部が計量膜から離れていることを特徴とする膜式ガスメーターの計量膜用軸受止め構造。 - 軸受は、膜板に押し付けてネジ止めする当板(22)に対して上下にアーム(23)を、当板から離れる方向に屈曲して形成し、アームの先部には軸を収容する軸通し孔(25)を設け、上下対称的な軸受の上部については、アームの付け根手前部分から延長板(24)を上方に向かってリブにまで突出し、延長板の先とリブの一方に凹部を、他方に凸部を設けてあることを特徴とする請求項1記載の膜式ガスメーターの計量膜用軸受止め構造。
