Abstract
It is an object of the present invention to provide a novel carrying apparatus for carrying spherical objects such as spherical semiconductors of silicon in which the spherical objects are not contacted with an inner surface of a pipe-shaped body while they are being carried in the pipe-shaped body. The carrying apparatus for carrying spherical objects is provided with a spiral current generating means for generating a spiral current of fluid, and the spiral current generated by the spiral current generating means is introduced into a passage of the spherical objects. The spiral current generating means includes a rotary shaft 3 in which a carrying passage 2 is formed in a direction of the central axis and a spiral groove 3b is formed at a predetermined position on the outer circumferential surface. Further, in the rotary shaft 3, a jet pipe 3a connecting the carrying passage 2 with the spiral groove 3b is formed.
