An article display tray is provided with a movement guide device, wherein cylindrical articles can move more smoothly in a communication portion of the article display tray, via which the pair of storage chambers are communicatively connected to each other, and further wherein an increase in size of the article display tray can be avoided. A pair of left-right force-applied portions and an arraying guide surface positioned between the pair of force-applied portions are formed on a rocking member positioned inside the rear-end communication portion of an article display tray. When one of the pair of force-applied portions is pushed rearward by a cylindrical article that is placed in one of a pair of left-right storage chambers, the other force-applied portion pushes forward a cylindrical article that is placed in the other storage chamber. When the aforementioned one cylindrical article that pushes the aforementioned one force-applied portion rearward comes into engagement with the arraying guide surface after pushing the aforementioned one force-applied portion rearward, the arraying guide surface returns the rocking member to a neutral position where the pair of left-right storage rooms are aligned in a leftward/rightward direction.

The invention claimed is: 1. An article display tray provided with a movement guide device, comprising: an article display tray including a pair of left-right storage chambers and a rear-end communication portion which communicatively connects rear end portions of said pair of left-right storage chambers to each other, cylindrical articles that are circular in cross section being movable between said pair of left-right storage chambers through said rear-end communication portion; and a base member mounted on said rear-end communication portion, said base member including an arc shaped front portion facing said storage chambers, a rocking member positioned inside said rear-end communication portion of said article display tray and capable of rocking about a rocking shaft extending in a vertical direction, said rocking member having an arc shape surface facing said storage chambers, the rocking shaft extending through said base member and a central portion of said rocking member, said rocking shaft rotatably supporting said rocking member, wherein said rocking member includes a pair of force-applied portions which are positioned at left and right ends of said rocking member on imaginary extension lines of said pair of left-right storage chambers, respectively, and an arraying guide surface positioned between said pair of force-applied portions, wherein, when one of said pair of force-applied portions is pushed rearward by one of said cylindrical articles which is placed in one of said pair of left-right storage chambers, and the other of said pair of force-applied portions pushes another of said cylindrical articles forward which is placed in the other of said pair of left-right storage chambers, and wherein, upon said one of said cylindrical articles pushing said one of said force-applied portions rearward so as to come into engagement with said arraying guide surface, said arraying guide surface returns said rocking member to a neutral position where said pair of left-right storage chambers are aligned in a leftward/rightward direction. 2. The article display tray provided with said movement guide device according to claim 1, wherein said article display tray or said movement guide device comprises a guide surface for moving one of said cylindrical articles which engages with said arraying guide surface to a position immediately before said one of said force-applied portions which is positioned ahead of said one of said cylindrical articles in a direction of movement thereof when said one of said cylindrical articles that engages with said arraying guide surface is pushed rearward by one of said cylindrical articles which is positioned at the rear end portion of said one of said pair of storage chambers. 3. The article display tray provided with said movement guide device according to claim 1, wherein at least one of said pair of force-applied portions is a curved surface. 4. The article display tray provided with said movement guide device according to claim 1, wherein guide grooves narrower in width than diameters of said cylindrical articles are formed on an article mount surface of said article display tray along a direction of movement of said cylindrical articles, said article mount surface supporting bottom surfaces of said cylindrical articles placed in said pair of storage chambers. 5. A movement guide device which is installed at a rear-end communication portion of an article display tray, wherein said article display tray includes a pair of left-right storage chambers and said rear-end communication portion which communicatively connects rear end portions of said pair of left-right storage chambers to each other, cylindrical articles that are circular in cross section being movable between said pair of left-right storage chambers through said rear-end communication portion, wherein said movement guide device comprises: a base member mounted on said rear-end communication portion, said base member including an arc shaped front portion facing said storage chambers, a rocking member capable of rocking about a rocking shaft extending in a vertical direction, said rocking member having an arc shape surface facing said storage chambers, the rocking shaft extending through said base member and a central portion of said rocking member, said rocking shaft rotatably supporting said rocking member; a pair of force-applied portions provided at left and right ends of said rocking member and positioned on extension lines of said pair of left-right storage chambers, respectively; and an arraying guide surface formed between said pair of force-applied portions, wherein, when one of said pair of force-applied portions is pushed rearward by one of said cylindrical articles which is placed in one of said pair of left-right storage chambers, and the other of said pair of force-applied portions pushes another of said cylindrical articles forward which is placed in the other of said pair of left-right storage chambers, and wherein, upon said one of said cylindrical articles pushing said one of said force-applied portions rearward so as to come into engagement with said arraying guide surface, said arraying guide surface returns said rocking member to a neutral position where said pair of left-right storage chambers are aligned in a leftward/rightward direction. 6. The movement guide device according to claim 5, wherein at least one of said pair of force-applied portions comprises a curved surface. 7. The article display tray provided with said movement guide device according to claim 2, wherein at least one of said pair of force-applied portions is a curved surface. 8. The article display tray provided with said movement guide device according to claim 2, wherein guide grooves narrower in width than diameters of said cylindrical articles are formed on an article mount surface of said article display tray along a direction of movement of said cylindrical articles, said article mount surface supporting bottom surfaces of said cylindrical articles placed in said pair of storage chambers. 9. The article display tray provided with said movement guide device according to claim 3, wherein guide grooves narrower in width than diameters of said cylindrical articles are formed on an article mount surface of said article display tray along a direction of movement of said cylindrical articles, said article mount surface supporting bottom surfaces of said cylindrical articles placed in said pair of storage chambers. 10. The article display tray provided with said movement guide device according to claim 7, wherein guide grooves narrower in width than diameters of said cylindrical articles are formed on an article mount surface of said article display tray along a direction of movement of said cylindrical articles, said article mount surface supporting bottom surfaces of said cylindrical articles placed in said pair of storage chambers.
