When the movable member 90 is in the inclined position, as shown in FIG. 9, the second surface 95 of the movable member 90 is in contact with the inclined surface 38a. As the movable member 90 moves in the direction of the curved arrow shown in FIG. 10, the second surface 95 of the movable member 90 moves away from the inclined surface 38a. In the arrangement shown in FIG. 10, the angle at which the first surface 38 of the movable member 90 is inclined with respect to the axial direction Z is smaller than the arrangement at the inclined position shown in FIG. 9.

  FIG. 11 is a third partial cross-sectional view illustrating a state of cleaning the passage through which the medicine passes according to the first embodiment. When the wiping member 61 further moves from the arrangement shown in FIG. 10, the movable member 90 also further rotates clockwise in FIG. The first surface 38 of the movable member 90 extends along the axial direction Z. Thereby, the first surface 38 of the movable member 90 comes into surface contact with the wiping member 61. The arrangement of the movable member 90 shown in FIG. 11 is referred to as a wiping position.

  With the wiping member 61 in contact with the first surface 38 of the movable member 90, the wiping member 61 moves downward as shown by the arrow in FIG. Sliding on the first surface 38 wipes the first surface 38. As the wiping member 61 moves downward along the inner peripheral surface 39, the plurality of movable members 90 are sequentially cleaned. As the wiping member 61 moves from the upper edge to the lower edge of the inner peripheral surface 39, all of the plurality of movable members 90 are cleaned.
