The movable bracket 64 is formed by bending such that the ball member 68 can contact both side surfaces of the metal plate.

The ball member 68 is positioned at the curvature portion of the rail groove portion 62 and the moving bracket 64 of the support frame 4 so that the moving bracket 64 prevents the simultaneous upward and downward friction by the screw member 46.

Therefore, the diameter of the exposed groove 69 of the fixing bracket 68 is smaller than the diameter of the ball member 68. Therefore, when the ball member 68 is not constrained, So that only a part of the ball member 68 is exposed, so that the ball member 68 is prevented from being separated.

The fixing bracket 68 is fastened to the shelf member 10 together with the moving bracket 64 by bolts or screws.

It is preferable that the moving bracket 64 and the fixing bracket 68 are screwed and fixed to the mounting bracket 70 provided at the edge of the shelf member 10.

It is preferable that the lower side of the mounting bracket 70 is configured so that its thickness gradually decreases toward the end portion thereof. This is because the loads of the supporting rack 10 and the height adjusting member 20 gradually decrease.

The shelf moving device of the present invention is characterized in that the shelf member 10 is housed in the storage room 2 by using the power provided by the height adjustment member 20 provided on the shelf member 10 in the support frame 94 provided at two places in the storage room 2, So that the shelf moving structure can be made compact, the storage space utilization can be enhanced, and the appearance can be improved.

The present invention can stably support the rotary belt 20 by having the elastic pressing portion 50 that provides the rotary belt 30 with tension.

The present invention supports the load by using the rail member (60) provided between the rack member (10) and the support frame (4), thereby allowing the rack member (10) to move up and down without shaking.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.
