PROBLEM TO BE SOLVED: To improve the metering precision of a metering instrument for powder attached to a container, by widening the adjustable range of a discharge volume and easily adjust it when making it variable. SOLUTION: This metering instrument 10 for powder attached to the opening 2 of a container 1 is constituted of a cup 20 of which the inflow of the powder is formed on the cylindrical side wall 21, a partition plate 30 hung in the cup 20, and a cap 40 attached to the upper end of the cup 20 and provided with a discharge opening 41 of the powder. The inside of the cup 20 is divided into a temporarily metering part A, a metering part B, and a discharge passage C, and the cap 40 and the partition plate 30 is vertically slid against the cup 20 to increase or decrease the volume of the temporarily metering part A and the metering part B, by vertically sliding the cap 40 and the cup 20. |
