PROBLEM TO BE SOLVED: To provide a quantitative discharge apparatus of adsorbent capable of preventing the leak of adsorbents easily.SOLUTION: While arranging separately a rotation part 51 which is included in a roll feeder 5 of the quantitative discharge apparatus 1 to the opening 22 of an adsorption room 21A which stores the adsorbent C, a closing plate 6 projecting from the rotation part 51 of a roll feeder 5 to the outside in a radial direction to face the external surface of an outer wall 25 of the adsorption room 21A in the axis line direction via an axis line direction gap d4. Moreover, the adsorbent C which is discharged from the opening 22 and intends to spread to the outside of the axis line direction is dammed with the closing plate 6 to stop inside the closing plate 6, and by blocking the further movement in the axis line direction the adsorbent C is prevented from leaking from between the outer wall 25 and the rotation part 51 to the lateral side. Thereby, because an escape gap d3 in the path direction between the outer wall 25 and a facing part 53a can be set up in comparatively great, the leak of the adsorbent C is prevented easily, without doing the adjustment work of fine gaps. |
