From the foregoing, it will be seen that the mechanism for locking the shelf structure rotator and resiliently blocking it to overcome its motion and holding it in the locked position can be simplified to hold the shelf structure rotor in a predetermined position, for example as shown in FIG. It is clear that it can be stopped in position with a locking member. This mechanism has a very robust and reliable actuation mechanism and occupies a very small area around the shelf rotor. Of course, locking member 220 can be arranged to be actuated from either side or both sides, if desired.

The above description is a representative example of a preferred embodiment of the present invention, and the present invention is not limited thereto.
