PROBLEM TO BE SOLVED: To adapt an article storage body to the environment requiring a precise work by forming a groove part or a recessed part in a location away from a contact position of a placement at a bottom part of an article storage body when the article storage body is placed at a specified placement to prevent the dust or the stain on the contact surface from intruding in the article storage body. SOLUTION: When an article storage body 8 is placed at the article feeding position, and a specified article is fed in a storage part, a stepped part 8H arranged on the outermost side in the bottom surface becomes the ground contact surface. When the article storage body 8 is stored in a carrying box 18, its contact surface 8H is confined in an enclosed space 20 between an upper bottom surface of the carrying box 18 and a bottom surface of the article storage body 8. In addition, when another article storage body 10 is stacked on the article storage body 8 in the carrying box 18, an upward recessed part 8F is put to coincide with a downward recessed part 10I to form an enclosed space 16. The dust and the stain adhered to the contact surfaces 8H, 10H of the article storage bodies 8, 10 are confined in the enclosed spaces 20, 16. |
