For example, it may be a square or rectangular square shape, a polygonal shape, a partial shape of a circle or an ellipse, a shape consisting of an arbitrary curve, or the like.

Further, the third slide restricting portion 24c is provided on the side side as shown in the AA cross-sectional view of FIG. 3, the BB cross-sectional view of FIG. 4, or the enlarged view of the broken line portion of the DD cross-sectional view of FIG. A second inner regulation wall 24d is provided slightly inward from the position. The second inner regulation wall 24d is formed so as to be higher than the bottom surface of the third slide regulation portion 24c at a position corresponding to the third slide regulation portion 24c in the first slide regulation portion 24a. In other words, the second inner regulation wall 24d is formed by cutting out a part of the outer wall in the concave shape of the first slide regulation portion 24a and leaving a part of the wall of the first slide regulation portion 24a. Will be done.

Next, the stacking of the shelf member 40 and the carrier 1 will be described with reference to FIG. 7. As shown in FIG. 7, the shelf member 40 can be detachably placed on the upper surface of the protruding side wall portion 24. That is, the shelf member 40 can be stacked on the carrier 1.

When the shelf member 40 is stacked on the carrier 1, the third slide restricting portion 24c provided on the lower carrier 1 and the second shelf member fitting portion 43 provided on the upper shelf member 40 Fits. The fitting restricts the movement of the upper shelf member 40 in the front-rear direction and the left-right direction.

Further, since the third slide restricting portion 24c has the same shape as the first shelf member fitting portion 42, when the second shelf member fitting portion 43 is fitted, the third slide restricting portion 24c and the second shelf member fitting are fitted. Even if the position is slightly deviated from the portion 43, the inclination of the third slide restricting portion 24c makes it easier to accept the second shelf member fitting portion 43.

According to the above configuration, when the shelf member 40 is stacked on the carrier 1, the second shelf member fitting portion 43 and the third slide restricting portion 24c are fitted to each other in a direction parallel to the side surface and in the side surface. The movement of the shelf member 40 in the orthogonal direction is restricted.

Further, the second shelf member fitting portion 43 fits into both the third slide restricting portion 24c and the first shelf member fitting portion 42. Therefore, the second shelf member fitting portion 43 can be used for both the case where the shelf members 40 are stacked and the case where the shelf member 40 is stacked on the carrier 1. Therefore, the structure of the shelf member 40 can be simplified.

In the present embodiment, the third slide restricting portion 24c has a concave shape and the second shelf member fitting portion 43 has a convex shape, but the third slide restricting portion 24c has a convex shape and the second shelf. Each shape may be replaced so that the member fitting portion 43 has a concave shape.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the embodiments obtained by appropriately combining the technical means disclosed in the different embodiments. Is also included in the technical scope of the present invention.
