In the article storage shelf described above, the beam member has the first facing surface portion in contact with the first support surface portion of the support member in addition to the second facing surface portion contacting the second support surface portion of the support member. In particular, in the article storage shelf described above, the side plate portion (19a) is separated from the fitting portion by the fitting portion (15a) and the side plate portion (19a) as the engaging portion is engaged with the engaged portion. By guiding in such a manner, the first opposing surface portion is moved to the side to be pressed against the first support surface portion. This makes it possible to increase the contact pressure generated between the first facing surface portion and the first support surface portion. When the first opposing surface portion and the first support surface portion are in contact with each other in this manner, the beam member can be firmly connected to the support member, but the height of the articles to be stored in the article storage shelf is changed. It was difficult to remove the beam members from the support members when changing the interval between the beam members. On the other hand, it is possible to make the beam member easier to remove by weakening the strength of the connection of the beam member to the support member, but in that case, it becomes difficult to ensure the rigidity of the article storage shelf.

Therefore, it is desired to realize an article storage shelf that facilitates the removal of the beam member and easily secures the rigidity.

In view of the above, the characteristic configuration of the article storage shelf includes a pair of support members arranged in a prescribed alignment direction, a plurality of beam members arranged along the alignment direction so as to connect the pair of support members, wherein the plurality of beam members are arranged vertically and arranged parallel to each other,
The plurality of beam members includes a first beam member and a second beam member.

According to these characteristic configurations, in a state where the first engaged portion is engaged with the first engaged portion and the first beam member is connected to the strut member, the second facing surface portion of the first beam member In addition to contacting the second strut face of the member, the first opposing face of the first beam member contacts the first strut face of the strut member. Therefore, the first beam member can be firmly connected to the support member. Further, in a state where the second engaged portion is engaged with the second engaged portion and the second beam member is connected to the support member, the fourth opposing surface portion of the second beam member corresponds to the second support surface portion of the support member. However, the third opposing portion of the second beam member does not contact the first strut surface portion of the support member. Therefore, although the strength of connection of the second beam member to the support member is lower than that of the first beam member, the second beam member can be easily removed from the support member. By firmly connecting the first beam member to the support member, it is possible to easily ensure the rigidity of the article storage shelf. It becomes easier to remove the member. This makes it easy to change the interval between the beam members by changing the connection position of the second beam member with respect to the support member. Therefore, according to this configuration, it is possible to easily secure the rigidity of the article storage shelf while facilitating the removal of the beam member.
