The lower guide body 4 is provided with a traveling roller 4b which rolls when the slide column member A reciprocates, and the slide column member A
Front end with a front stop member 12 for stopping only, located in the opening S ₁ side from the front side stop member 12, rotates on a horizontal plane, the guide roller 13 as a lower portion substantially abutting state of the hinged door 10 The door stopper opening / closing device in which the side stopper B is attached to the front end of the lower guide rail 1 makes it possible firstly to make the movement of the sliding column member A extremely smooth, and secondly to reduce the weight of the door 10. text to those that can sufficiently endure against, hinged door 10 with the slide pillar a third, it can be a very good movement in the depth direction of the storage room S, the closed state of the opening S ₁ to the fourth In addition, there is an effect that rattling of the hinged door 10 can be prevented.

The above effect will be described in detail. The lower guide 4 attached to the lower end of the slide column member A includes a lower guide rail 1.
Is mounted with a running roller 4b adjacent to the guide groove 4a to be inserted. Therefore, when the slide column material A reciprocates along the upper and lower guide rails, the lower guide body 4 is rotated while the traveling roller 4b mainly rotates on the floor surface F.
Since but moving, running of the lower guide member 4 can be made very smooth, it can be satisfactorily opened and closed in the closing operation and the opening S ₁ of the housing chamber S of the thus hinged door 10.

Further, even if a pressure due to the weight of the sliding column member A and the hinged door 10 is applied to the lower guide member 4 by the running roller 4b provided on the lower guide member 4, the lower guide rail 1 does not come into strong contact with the lower guide rail 1 without sliding. The movement of the column material A in the depth direction of the storage room S can be maintained smoothly, and in this type of device, a relatively heavy hinged door 10, which has been considered extremely difficult, can be used.

The front end side stopper B is arranged at the front end of the lower guide rail 1 so that the slide column material A
A front stop member 12 for stopping the only one that is a guide roller 13 positioned from the front side stop member 12 to the opening S ₁ side, the guide rollers 13 is to rotate in a horizontal plane.

By mounting such a front end side stopper B on the opening S ₁ side of the lower guide rail 1, the slide column member A can be reliably stopped at the opening S _{1 by the} front side stop member 12. The hinged door 10 can be used as the opening S
It protrudes outward from _{1 and} can perform a good swing operation around the slide column member A.

A guide roller 1 rotating on a horizontal plane
3 is located at the opening S ₁ from the front stop member 12, so that the door 10 moves while contacting the guide roller 13 in the depth direction of the storage chamber S when the door 10 is opened and closed. By doing so, the guide roller 13 rotates on a horizontal plane, and the swing of the hinged door 10 is prevented, and a stable operation can be obtained. In addition, in the closed state of the hinged door 10, the guide roller 13 abuts on the lower end portion on the back surface side of the hinged door 10, thereby preventing the swinging door 10 from rattling.

Further, the opening and closing operation is performed while the hinged door 10 is in contact with the guide roller 13 that can rotate on a horizontal plane, so that the hinged door 10 is less likely to be scratched. In particular, when the hinged door 10 is made of wood, the surface is softer than that of the metal hinged door 10 and therefore is easily scratched. However, in the present invention, the presence of the guide roller 13 of the front end side stopper B is Even when the wooden hinged door 10 is used, it can be made hard to be scratched.
