PROBLEM TO BE SOLVED: To securely carry a number of small springs in a casing while eliminating their entanglement, and carry items that are easily entangled with each other like springs by eliminating problems due to automation, rationalization, manpower saving, etc., in carrying. SOLUTION: An openable/closable casing 1 having an air supply/discharge ports 5 and 6 is provided. A bottom surface 101 of the casing 1 is roughly shaped like a bowl in a truncated form, and a ceiling surface is roughly shaped like a ridge. An inclination surface 101a of the bottom surface 101 that is roughly shaped like a bowl, and an inclination surface of the ceiling surface that is roughly shaped like a ridge are positioned roughly in the same direction.
