PROBLEM TO BE SOLVED: To provide a fixed quantity supply device that is able to accurately measure a material.SOLUTION: A fixed quantity supply device 1 comprises: a measuring container 2 the internal space of which has a spherical shape; and a hollow shaft 3 penetrating the center of the measuring container 2. The inside of the measuring container 2 has: a sectioning plate 7 rotatable accompanying rotation of the hollow shaft 3; and a stopper 8 limiting a rotating range of the sectioning plate 7 by filling the area of a central angle θ1 of the internal space of the measuring container 2 in a plan view. The sectioning plate 7 has: a straight part 7a fixed to the hollow shaft 3; and an arcuate part 7b disposed in close contact with an internal wall of the measuring container 2. A wall of the hollow shaft 3 has a notch 3a with a central angle θ2, formed over the area where the hollow shaft 3 penetrates the measuring container 2. The central angle θ1 of the stopper 8 and the central angle θ2 of the notch 3a satisfy the following relations: θ2<θ1, θ1≥180°.SELECTED DRAWING: Figure 1 【課題】原料を正確に計量することができる定量供給装置を提供することを目的とする。【解決手段】定量供給装置１は、内部空間が球状に形成される計量容器２と、計量容器２の中心を貫通する中空シャフト３とを備える。計量容器２の内部には、中空シャフト３の回転に伴って回転可能な区切り板７と、平面視で計量容器２の内部空間のうち、中心角θ１の領域を埋めて区切り板７の回転範囲を制限するストッパ８とが収容されている。区切り板７は、中空シャフト３に固定される直線部７ａと、計量容器２の内壁に密接する円弧部７ｂとを有する。中空シャフト３の壁には、中空シャフト３の計量容器２を貫通する領域にわたり、中心角θ２の切欠き部３ａが形成されている。ストッパ８の中心角θ１と切欠き部３ａの中心角θ２とは、θ２＜θ１、θ１≧１８０°の関係を満たす。【選択図】図１
