To permit to charge a hydrophobic materials definitely to a desired position without causing clogging of a hydrophobic material when a charging machine is installed on a motor vehicle by mechanizing the charging of hydrophobic materials thereby reducing a labor cost and shortening the period of work.

This machine incorporates hydrophobic materials and its casing includes a fixed hopper 12, a hopper portion 10 having a movable hopper 11 which is arranged in parallel to the fixed hopper 12 and can be tilted so as to have the fixed hopper 12 side located at the downward side, and screw shafts 23, 24 having a screw vane at outer periphery built inside the casing. A first conveyor 21 coupled and fixed to the carrying outlet at a lower portion of the fixed hopper 12 and a discharge outlet for hydrophobic materials are provided at the tip portion and are connected in series with the first conveyor 21 and projected out from the hopper portion 1, and also a screw conveyor 20 consisting of the screw conveyor 22 separable from the first conveyor 21 are provided.
