PURPOSE: To easily supply a large quantity of vinyl bags onto a rod, by supplying bags bodies in the state where rods are pulled out one by one.

CONSTITUTION: A bag-shaped accommodation device is equipped with a rod 1, accommodation part 6b, and a driving-out part 3. The driving-out part 3 is equipped with a slide mechanism 4a and a traction mechanism 4b. A wire 4d is pulled by stepping on a pedal 4c by feet, and the rod 1 is shifted to the left side. A bag body pressing part 2 is pushed upwardly by a pushing-up part 1a through the shift of the rod 1, and the insertion of a vinyl bag is facilitated. In this state, the vinyl bag 5 is supported by the rod 1 in a half bent state, and when the foot is separated from the pedal 4c, the rod 1 is returned into the accommodation part 6b by a spring mechanism 4j, and the bag pressing part 2 is turned down to press the vinyl bag 5 onto the rod 1. Accordingly, the rod is individually pulled out and the bag body is mounted, by assembling a mechanism for sliding the rod individually, and the workability in supplying bag bodies can be improved.
