To provide a shelf facility having a movable shelf body capable of sufficiently responding to an offset load when a movable shelf body is moved projectedly.

A shelf frame 1 is provided with the movable shelf body 40 that is supported and guided by a guide device 10 and can move back and forth, and the lower part of the shelf frame 1 is provided with a falling preventing body 60 movable back and forth. An interlocking means 70 for moving the falling preventing body 60 back and forth in cooperation with the movement of the movable shelf body 40 is provided. The falling preventing body 60 can be moved projectedly via the interlocking means 70 when the movable shelf body 40 is moved projectedly and forward, and the falling preventing body 60 can be moved backward via the interlocking means 70 when the movable shelf body 40 is moved backward. When a projecting length of the falling preventing body 60 is set sufficient, the offset load when the movable shelf body 40 is moved projectedly can sufficiently be responded, and a stable state of preventing falling can be kept always regardless of a placed load. Since the falling preventing body 60 is moved back and forth, a floor surface B can be used effectively.
