Immediately before the drawer 31 is placed in the predetermined storage position and when the drawer 31 starts to be drawn out from the predetermined storage position, the upper bottom of the gradually shallower portion of the long groove front end 351 comes into contact with the protrusion member 34. The drawer 31 can be smoothly reached to the predetermined storage position or can be started to be drawn from that position. In the operation of moving the drawer 31 in and out, when each protruding member 34 is loosely fitted in the deep portion of the long groove 35, the drawer lower surface is supported by the drawer receiving plate 321. This allows the drawer to move stably.

The drawer pull-out prevention mechanism in the drawer device is not limited to that in the drawer devices 1, 2, and 3 described above. 5 (A) and 5 (B) show another example of the drawer pull-out prevention mechanism by taking the uppermost drawer device 1 as an example. In this example, a rotary member engaging recess 43 is formed at the front end of the drawer 11. The engaging recess 43 is formed in the form of a notched recess having a certain depth upward in a portion extending over the lower surface and the side surface of the front end of each of the left and right drawer side plates a. Further, a long groove 45 which is continuous with the recess 43 and extends rearward in the pulling-out / retracting direction and opens downward, laterally and rearward is formed in a region extending over the lower surface and the side surface of each side plate a. . The rear end of the long groove may be closed, but is open rearward here. The long groove 45 may extend slightly rearward from the engagement recess 43 to the rear. In the drawer insertion portion 42, a circular rotary member 44 is rotatably supported on the inner surface of the front end portion of the chest main body side plate 102 facing the side plates a of the drawer 41. The long groove 45 has a vertical depth that gradually decreases from the rear end of the groove toward the front end of the groove, and the depth of the rear end is such that the rear end is located at the position of the rotating member 44. At this time, the bottom surface of the drawer is the depth to be placed on the drawer receiving plate 121.

In the state where the drawer 1 is arranged at the predetermined storage position, the left and right engaging recesses 43 of the drawer 1 are fitted into the rotating member 44 of the drawer insertion portion 12, and the lower surface of the drawer is on the drawer receiving plate 121. Placed on. Also in this drawer device, even if a force is applied to the drawer 11 in the direction of extraction, or if the drawer 11 is pulled as it is, the engaging recess 43 of the drawer has the engaging protrusion 44 (rotating member) of the drawer insertion portion 12. I'm stuck in, and I can't get out. When the drawer 11 is opened, it can be easily opened by slightly raising the drawer front end, removing the engagement recess 43 of the drawer from the engagement protrusion 44 of the drawer insertion part, and pulling it out to the front. Also in this case, the drawer insertion portion 12 is formed with a drawer elevating space S above the drawer box portion where the drawer 11 can be lifted in this way.

Further, in the drawer device 1 shown in FIG. 5, when the drawer 11 is inserted into the drawer insertion portion 12, the drawer 11 is pulled up from the predetermined storage position until it reaches the predetermined storage position. Normally, the drawer is moved with the slanted long groove 45 of the drawer 11 placed on the rotary member 44 of the drawer insertion portion, and at this time, the rotary member 44 can be rotated, so that the drawer is smoothly moved.
