SOLUTION: This dust collector for a powder charge port is placed near the powder charge port and comprises a main body which consists of an inner wall, an outer wall, an upper wall, a bottom wall, and two terminal walls facing each other, these walls forming a hollow inner space; an inlet opening arranged on the inner wall; another inlet opening which opens along the bottom part of the inner wall; an outlet port capable of being connected to a suction device; and flexible platy members attached to the upper wall or its vicinity. The inlet opening arranged on the inner wall comprises vertical slits arranged in the direction from one terminal wall to the other terminal wall with some distances between the slits and a horizontal slit arranged on the inner wall in the vicinity of the upper wall or near the part lower than the flexible platy members.
