PROBLEM TO BE SOLVED: To provide a bag holding structure which achieves both of accurate holding of a bag that can endure excessive tensile load, and easy attachment/detachment of the bag.SOLUTION: A structure for holding the bag bg has: paired rotating bodies 4 and 5 having meshing parts 40 and 50 in which a plurality of teeth for holding the bag bg in-between are arranged, and capable of rotating around shafts parallel with each other in a state where the meshing parts 40 and 50 are meshed with each other; supporting parts 6 rotatably supporting both rotating bodies 4 and 5 so that the meshing parts 40 and 50 can come in contact with/be separated from each other relatively; and an energizing part 7 energizing one meshing part 40 in a direction going toward the other meshing part 50. |
