The rotational axis (C) of the rotary disk (1) is inclined. The center axis of each of the receiving holes (8) is arranged on an imaginary conical surface (12) having this rotational axis (C) as its center axis and an apex angle (.theta.) of 60.degree. to 120.degree.. The powder hopper (6) is disposed on the lateral side portion of an opening (8a) of the receiving hole (8) at a vacuum sucking portion (9) and a boss portion (28) supporting the rotational axis (34) of the agitator (7) is arranged above the powder hopper (6). This apparatus is suitable for being used at the step of filling various kinds of powder, especially injection or the like powdered pharmaceutical product requiring the accuracy of the amount …
