DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings and FIGS. In FIG. 1, reference numeral 1 denotes a refrigerator main body. The main body 1 divides an insulating box body filled with a heat insulating material 4 between an outer box 2 and an inner box 3 by partitioning members 5 and 6 filled with the heat insulating material 4. Refrigerator compartment 7, freezer compartment 8,
They are arranged in the order of the vegetable room 9. Each storage room is provided with a door 10, 11a, 11b, 12 which can be opened and closed freely. With respect to the storage rooms (in the embodiment, the freezing room 8 and the vegetable room 9 in the embodiment) below the central part, drawers described later are provided. It is an expression door.

The freezer compartment 8 is provided with a partition 13 between the left and right sides of the opening to divide the opening into upper and lower portions, and with drawers 8a and 8b above and below the partition 13 respectively. The vegetable compartment 9 is composed of doors 11a and 11b,
It consists of a pull-out door 12 with 9a.

Hereinafter, one embodiment of the present invention will be described with reference to a freezing room 8.
An example will be described with reference to the upper part of FIG. 2 to 5, guide rails 14 having a substantially U-shaped cross section are disposed substantially horizontally on opposed inner surfaces in the freezing chamber 8, and a support roller 14 is provided on the front side of the guide rails 14. ing. Door rail slidably mounted on the support roller 15 on the back side of the door 11a
A rolling roller 17 that rolls along the guide rail 14 is provided at the rear of the door rail 16 and the guide rail
The drawer-type door 11a is configured to be able to be pulled out by the door rail 16 and the door rail 16.

A guide groove 18 extending in the front-rear direction and extending in the front-rear direction on the upper surface of the partition body 13 and comprising a pair of projecting pieces 18a and 18b facing each other is formed. A rectangular projecting piece 19 is provided at the lower portion of the rear surface of the rear surface of the door, which extends back and forth, is guided by the guide groove 18 so as to be freely detachable, and regulates the left and right positions of the drawer type door 11a. The guide groove 18 has its front end expanded outward, and a projection 19
Is guided so that the tip of the projecting piece 19 can easily enter the groove.

As shown in FIG. 5, the width D of the projecting piece 19 is substantially equal to the inner diameter width D 'of the guide groove 18.
When the protruding piece 19 is guided to the right side, the left and right rattling is minimized. Further, the guide groove 18 is provided integrally with the partition 13.

In the above configuration, the drawer type door 11a
When the door is closed, the protruding piece 19 is guided by the guide groove 18 as shown by a solid line arrow in FIGS.
a) It is possible to improve the quality of the appearance simply and inexpensively without any misalignment between the main unit and the door, and to improve the quality of the appearance because there is no rattling between the left and right of the door. Become.

[0019]

As described above, according to the present invention, when the drawer-type door is closed, the projecting piece is guided by the guide groove, and the displacement of the drawer-type door is restricted.
