Such a deceleration can be performed six times, since six elastic strips 23 are provided on each support bar 9.

After the deceleration by the elastic strip 23, the storage box 3 abuts against the guide surface 24 of the deceleration block 17, and the deceleration block 17 disperses the force of the downward sliding of the storage box 3 again by the guide surface 24, thereby further reducing the downward sliding speed of the storage box 3. Since three speed reduction blocks 17 are provided on each support rod 9, such speed reduction can be performed three times.

When the deceleration block 17 is located at the position of the deceleration groove 22, the deceleration block 17 is inserted into the deceleration groove 22 under the restoring action of the compression spring 18, the groove wall of the deceleration groove 22 limits the movement of the deceleration block 17, and the sliding speed of the storage box 3 is further reduced.
