PURPOSE: To contract the space occupied for setting of a storage conveyor by forming a pushing surface engaged with and disengaged from a carrying matter in the upper position of the rising and falling support shaft of a rising and falling hook, and forming a pushing external force working surface in the lower position.
CONSTITUTION: A rising and falling hook 2 has a pushing surface 11 colliding with an engaging plate 10 vertically provided on a carrying matter in the position upper than a rising and falling support shaft 3. The circumferential surface of a rotatably supported roller R is formed as a pushing external force working surface 12 in the position lower than the rising and falling support shaft 3. The pushing external force working surface 12 pushes the pushing surface forward to the position shown by the chain line by the action of an external force to separate the pushing surface 11 from the engaging plate 10 of the carrying matter. At this separation, the upper end 11' of the pushing surface 11 falls drawn, drawing an arch to accelerate the engaging plate 10 of the carrying matter forward. Then, the upper end 11' is partially cut to reduce the pushing quantity as much as possible, so that the fluctuation of the stopping position of the carrying matter is suppressed.
