By inserting the claws (11) formed on the lower edge and the rear edge of the partition plate (9) into (10), they are detachably provided at equal intervals.
[0013]
The shelf plate (7) includes a front jump prevention bar (12) that prevents the article (C) from dropping due to jumping forward, and an upper jump prevention bar (13) that prevents jumping upward. Is provided so as to be rotatable in the front-rear direction.
[0014]
The front jump-out prevention bar (12) is located at the upper center of the pair of left and right side plates (14) and (14) in the tray (8), and extends to the front supported by a pin (15) facing in the left and right direction. The distal ends of the pair of first levers (16), (16) are connected to each other by a connecting rod that faces in the left-right direction, and is formed in a U-shape facing backward in plan view.
[0015]
The upper jump-off preventing bar (13) is formed by connecting the distal ends of a pair of left and right second levers (18) extending upward from an intermediate portion of the first lever (16) with a connecting rod (19) facing in the left-right direction. They are connected and formed in a U-shape facing downward in front view.
[0016]
On the upper and front edges of the side plate (14), projecting pieces (20) and (21) projecting outward are projected, and the upper projecting piece (20) extends from the middle of the side plate (14) to the rear. The stopper 20a is formed so that the front end of the first lever 16 receives the first lever 16 tilted rearward. Further, the front projecting piece (21) is formed from the middle to the lower part of the side plate (14), and the upper end serves as a front stopper (21a) for receiving the first lever (16) in a state of being tilted forward.
