Abstract
The invention provides a quantitative discharge apparatus of an adsorbing material. The apparatus is easy to prevent leakage of the adsorbing material. A rotating part (51) of a roller feeder (5) of the quantitative discharge apparatus (1) is separatedly configured relative to an opening (22) of an absorbing chamber (21A) accommodating the adsorbing material (C), and a hole blocking plate (6) is also provided which radially outwardly extrudes from the rotating part of the roller feeder and is opposite to an outer surface of an outer wall (25) of the absorbing chamber (21A) across an axial-direction gap (d4) in an axial direction. The adsorbing material discharged from the opening and intending to spread outward in the axial direction can be blocked by the hole blocking plate, and be stopped at inner side of the hole blocking plate, thereby preventing a further outward movement in the axial direction and thus prevention leakage of the adsorbing material from a position between the outer wall and the rotating part to a side. Therefore, a radial backoff gap between the outer wall and an opposing part (53a) can be relatively greatly arranged, without adjustment of fine gaps, thereby being easy to prevent the leakage of the adsorbing material.
