In the unfolded state, the slit is formed so as to be separated in the second direction from the end of the rack member in the second direction perpendicular to the first direction by a distance equal to or less than the predetermined thickness. Here, the "second direction" means a direction perpendicular to the first direction in the plane of the unfolded state.

The storage rack can be attached to a mounting surface (for example, a wall surface) by the following procedure. First, the base member is attached to the surface to be attached with the front surface of the base plate facing the surface to be attached. Here, a part of the surface of the base plate is provided with a spacer having a thickness in a normal direction perpendicular to the surface. Therefore, when the base member is attached to the attachment surface, a gap is formed between the attachment surface and a portion of the surface of the base plate where the spacer is not provided. In this state, the rack member is installed on the base member by inserting the base plate into the slit of the rack member. When replacing the rack member, the installed rack member is removed from the base plate, and the base plate is inserted into the slit of another rack member. Thus, according to the storage rack according to the present disclosure, the rack member can be easily attached to and detached from the base member by inserting and removing the base plate from the slit of the rack member.
