A constant quantity discharging device for measuring and discharging a constant quantity of powdered object from a powdered object container includes a fixed cap, a rotary disk, and a rotary cap which are coupled and mounted to the container. The rotary disk and the rotary cap sandwiching the fixed cap are rotated manually as a unit with respect to the fixed cap. The rotary disk has a powder taking out aperture, the fixed cap has a powder storing aperture, and the rotary cap has a powder discharging aperture. The positional relationships of these apertures are shifted circumferentially as the rotary disk and the rotary cap are rotated with respect to the fixed cap such that these apertures are sequentially communicated with an adjacent aperture. As a result, the powder in the container is transferred to the powder storing aperture through the powder taking out aperture of the rotary disk, and then the powder is discharged from the powder storing aperture through the powder discharging aperture of the rotary cap. The constant quantity of powder is determined by the volume of the powder storing aperture.
