To carry a fixed quantity of raw material powder by rotating a screw by specified turn without using a driving means such as a motor.

An apparatus 1 for carrying raw materials, which carries and discharges the powder raw material in a raw material storing container 10 from a raw material discharging opening 13 by rotating the screw 15, includes: an opening/closing member 101 for closing the raw material discharging opening 13 so as to be freely openable/closeable; a pinion gear 16 coaxially provided on the screw 15; a rack 20 held on the body so as to be freely movable back and forth, and provided so as to be meshed with the pinion gear 16; and a rack movement regulating means for controlling these meshing. This rack movement regulating means makes this rack 20 mesh with the pinion gear 16 only when the rack 20 moves in the direction for rotating the screw 15 in the direction for discharging the powder raw material from the raw material discharging opening 13.
