The folding is done manually. Legs 47 are provided at the lower four corners of the rectangular frame 41.

"Effect of the embodiment"
According to the above embodiment, the following effects are obtained.
(1) As shown in FIGS. 1 and 4, by rotating the rotation plate 11 (see the arrow in the dashed line in the figure), the positions of the holding arms 9 are closest to each other (in the figure, the rotation). Among the eight dash-dot lines indicating the plate 11, the inner bag can correspond to the small garbage bag 1 (in the drawing, the inner one-dot chain line among the two two-dot chain lines indicating the garbage bag 1 in the figure). Show).

On the contrary, if the holding arms 9 are located farthest from each other (in the figure, indicated by the four outermost four dot-dash lines among the eight one-dot chain lines indicating the rotation plate 11), the large garbage bag 1 can be handled (see FIG. Among the two alternate long and two short dashes lines that indicate the garbage bag 1, the outer one is indicated by an alternate long and short dashed line).
In this way, the difference between the small garbage bag 1 and the large garbage bag 1 that can be handled can be made sufficiently large. Further, since the rotation plate 11 can be rotated 360 degrees in a substantially horizontal plane, the closest position and the farthest position can be obtained by rotating 180 degrees from either of the two directions.

  Furthermore, the rotation position of the rotation plate 11 can be set to various positions by rotating the rotation plate 11 by an arbitrary number of star projections. Further, the rotation positions of the respective rotation plates 11 can be different from each other. In this way, the difference between the small garbage bag 1 and the large garbage bag 1 that can be handled is fine, can increase the valuation, and can sufficiently cope with various sizes of the garbage bags 1.

(2) As shown in FIG. 2, since the holding arm 9 has elasticity, the holding arm 9 bends with the upper end inserted into the folded edge 5 of the opening 3 of the garbage bag 1 (the upper side in FIG. 1). The opening 3 can be kept firmly open without slackening (see the dashed line arrow). Further, when the size of the garbage bag 1 is slightly different depending on the width of the flexure, it can be dealt with without rotating the rotating plate 11. Further, by applying tension without slackening the opening 3, it is possible to prevent the edge portion 5 folded back from the garbage bag from coming off and falling off.

(3) Since the fixing position where the lower end of the holding arm 9 is fixed to the rotating plate 11 can be changed, the distance between the fixing position and the rotating shaft 35 can be changed. The small garbage bag 1 that can be made can be made smaller. Similarly, the large garbage bag 1 that can be handled can be made larger. In FIG. 4, this distance is set large. However, it can be set smaller. For this reason, the kind of size of the garbage bag 1 which can respond can be diversified.

(4) Since the rotating posture of the rotating plate 11 can be maintained by fitting the convex portion having a regular polygonal cross-sectional shape, that is, a star shape having ten protrusions 37, and the concave portion, the rotating posture maintaining means 15 Thus, the manufacturing cost of the trash bag simple holding frame trash box 7 can be reduced.
(5) Fixing in which the lower end of the holding arm 9 is fixed to the rotating plate 11 by fitting with a predetermined cross-sectional shape, that is, with a convex or concave portion having a star shape having ten protrusions 37 in this embodiment. Since the position can be changed, the structure of the changing means 17 can be simplified, and the manufacturing cost of the trash bag simple holding frame trash box 7 can be suppressed.

(6) Since the regular polygonal cross-sectional shape of the rotation posture maintaining means 15 and the predetermined cross-sectional shape of the changing means 17 are the same shape, that is, a star shape having ten protrusions 37, the garbage bag simple holding frame The manufacturing cost of the trash can 7 can be suppressed.
(7) Since the base portion 13 can be folded, it is convenient to carry and store the trash bag simple holding frame trash box 7.
(8) As shown in FIGS. 1 and 4, the rotation of the four rotation plates 11 is unified to form a regular square in which the shape of the opening of the bag is arranged. However, the four rotation plates 11 can be rotated independently, and the shape of the opening of the bag can be another irregular quadrangle. In this way, by making it possible to change the opening shape, it is possible to obtain an optimum opening shape in accordance with the shape of the installation space of the trash bag simple holding frame trash box 7 or the like.
