PURPOSE: To enable the oblique movement, and to dispose a plurality of box portions in a box portion passage by driving a linear motor unit thereby travelling both spiral disks along a spiral/oblique passage by means of the propulsion force applied between a primary coil and secondary coil.
CONSTITUTION: A spiral/oblique passage 3 extending in a spiral shape is formed on the whole peripheral surface of an elevating passage 2 at an oblique angle of 8 degrees and a pitch of 4m. On the lower surface of the spiral/oblique passage 3, rails 4 and a reaction plate 5 as a secondary coil of a linear motor section are disposed along the spiral/oblique passage 3. In a box portion 1, shaft bodies 6 are respectively projected on the upper and lower sides so as to be rotatable about a vertical axis 6a. A spiral disk 8 attached to the shaft body 6 through an arm 7 is freely fitted in the spiral/oblique passage 3. A plurality of wheels 9 and a primary coil 10 of the linear motor portion are suitably attached on the lower surface of the spiral disk 8.
