This guide member (for example, a U-shaped member in cross section) 8 is secured to the main body 3 by, for example, welding, ensuring a space that does not hinder the stopper portion 63 from moving up and down.
Reference numeral 5 ′ denotes an operating body rotatably supported by the main body 3, and one end 51 ′ of the operating body 5 ′ is located at a position facing the inside of the shelf T (see FIGS. 20 and 21). 1 is a part where the pallet 2 loaded with 1 abuts. The other end 52 ′ of the operating body 5 ′ is configured to support the lower end portion of the stopper portion 63.
Note that the operating body 5 'is supported so as to rotate around the shaft 53'.

また、9は、作動体5’の動きを規制する規制部材で、規制部材9は、回動する作動体5’に当接して作動体5’の動きを規制するもので、例えば、本体3に溶接により固着される凸状部材である。
この本体3に取り付けられた規制部材9により、作動体5’の一端51’が、常時(作動体5’の一端51’に荷1を搭載したパレット2が当接しない場合)は、図22に示すように、水平部材Hの上端面H1を超える位置に、作動体5’の他端52’がストッパー部63の下端部を支持するように、作動体5’の動きを規制している。なお、特に、作動体5’の一部が、図22に示すように、水平部材Hの下端面H2を超えない位置になるように調整されているのが好ましい。
これは、作動体5’の一部が、水平部材Hの下端面H2を超えると、図22に示す水平部材Hの下の部位のスペースに荷1を搭載したパレット2を収納する際、下端面H2を超えた作動体5’の一部に荷1が接触する場合があるからである。
Reference numeral 9 denotes a regulating member that regulates the movement of the operating body 5 ′. The regulating member 9 abuts on the rotating operating body 5 ′ to regulate the movement of the operating body 5 ′. It is the convex-shaped member fixed to by welding.
Due to the restriction member 9 attached to the main body 3, the one end 51 'of the operating body 5' is always (when the pallet 2 carrying the load 1 is not in contact with the one end 51 'of the operating body 5') as shown in FIG. As shown in FIG. 3, the movement of the operating body 5 ′ is regulated so that the other end 52 ′ of the operating body 5 ′ supports the lower end of the stopper portion 63 at a position exceeding the upper end surface H1 of the horizontal member H. . In particular, it is preferable that a part of the operating body 5 ′ is adjusted so as to be in a position not exceeding the lower end surface H2 of the horizontal member H as shown in FIG.
This is because when a part of the operating body 5 ′ exceeds the lower end face H2 of the horizontal member H, when the pallet 2 loaded with the load 1 is stored in the space below the horizontal member H shown in FIG. This is because the load 1 may come into contact with a part of the operating body 5 ′ beyond the end face H2.

そして、図22に示すように、作動体5’の一端51’に荷1を搭載したパレット2が当接しない状態にあっては、ストッパー部63の先端部が水平部材Hの上端面H1を超えない位置に設定され、また、作動体5’の一端51’に荷1を搭載したパレット2が当接すると、図23、図26及び図27に示すように、作動体5’の一端51’が移動してストッパー部63の先端部が水平部材Hの上端面H1を超えて移動し、荷1を搭載したパレット2の動きを防止することとなる。     As shown in FIG. 22, when the pallet 2 loaded with the load 1 is not in contact with the one end 51 ′ of the operating body 5 ′, the tip end portion of the stopper portion 63 forms the upper end surface H1 of the horizontal member H. When the pallet 2 loaded with the load 1 is brought into contact with one end 51 ′ of the operating body 5 ′, as shown in FIGS. 23, 26 and 27, the one end 51 of the operating body 5 ′ is set. 'Is moved, and the tip end portion of the stopper portion 63 moves beyond the upper end surface H1 of the horizontal member H, thereby preventing the movement of the pallet 2 on which the load 1 is mounted.

従って、本実施例の図20乃至図27記載のパレットの移動防止装置Pにあっても、上述の「パレットの移動防止装置P」と同様、作動体5’の一端51’に荷1を搭載したパレット2が当接しない状態にあっては、ストッパー部63の先端部が水平部材Hの上端面H1を超えない位置に設定されて本体3に取り付けられているため、パレット2が棚Tに搬入される際、ストッパー部63が邪魔とならず、搬入をスムーズに行うことができ、また、作動体5’の一端51’に荷1を搭載したパレット2が当接すると、作動体5’の一端51’が移動してストッパー部63の先端部が水平部材Hの上端面H1を超えて移動し、荷1を搭載したパレット2の動きを防ぐことができる。     Accordingly, even in the pallet movement preventing device P shown in FIGS. 20 to 27 of the present embodiment, the load 1 is mounted on the one end 51 ′ of the operating body 5 ′ as in the above-described “pallet movement preventing device P”. In the state where the pallet 2 does not come into contact, the tip of the stopper 63 is set at a position that does not exceed the upper end surface H1 of the horizontal member H and is attached to the main body 3, so that the pallet 2 is placed on the shelf T. When being carried in, the stopper portion 63 does not get in the way and can be carried in smoothly, and when the pallet 2 carrying the load 1 is brought into contact with one end 51 ′ of the working body 5 ′, the working body 5 ′. One end 51 ′ of the first end 51 ′ moves so that the tip of the stopper 63 moves beyond the upper end face H 1 of the horizontal member H, and the movement of the pallet 2 carrying the load 1 can be prevented.
