よう量室下方に設けられ、上記測定皿に皿受軸を
介して係合する天びん機構を備えた天びんにおい
て、上記ひよう量室の床部を上下二枚の床板によ
り所定の空間を挟んだ二重構造とし、かつ、その
二枚の床板を上記皿受軸が貫通する部分の隙間を
、その下部床板の隙間に対して上部床板が小さく
なるよう構成するとともに、上記空間に上記下部
床板の隙間から流入した空気を上記ひよう量室内
部へと逃がすための通気孔を、当該ひよう量室の
壁体近傍に設けたことを特徴とする電子天びん。 In a balance equipped with a weighing chamber that houses a measuring pan inside, and a balance mechanism that is provided below the weighing chamber and engages with the measuring pan via a pan bearing shaft, the weighing chamber has a weighing chamber. The floor part has a double structure with a predetermined space sandwiched between two upper and lower floor plates, and the gap where the plate bearing shaft passes through the two floor plates is the gap between the upper floor plate and the lower floor plate. In addition, a ventilation hole is provided near the wall of the capacity chamber to allow air flowing into the space from the gap in the lower floor plate to escape into the capacity chamber. Features of electronic balance.
