摘要：PURPOSE:To easily pull out a screw from a casing so as to improve the work efficiency by projecting the output side end portion of a driving shaft inside a casing to be engaged with one end of a screw shaft portion, and supporting and sealing only the other end side of the shaft by the second bearing and a seal member. CONSTITUTION:In case of taking out a screw 12 from a casing 1, a mounting member 21 where the second seal member 22 and the second bearing 8 are installed is detached from an annular member 23, and the screw 12 is pulled out toward the side of an outlet 4 side of the casing 1, whereby one end 13a of a shaft portion 13 of the screw 12 is separated from the output side end portion 11a of a driving shaft 11 so as to easily take out the screw. During the rotation of the screw 12, a blade portion 2b of the screw 12 is subjected to the reaction force of feeding out a transported article to the outlet 4 side and energized in the direction of adhering to the shaft 11, so that the screw 12 is prevented from moving in the direction of separating from the shaft 11.
