A first plate of the plurality of plates includes a first coupling portion formed along an edge of the first plate, and a second plate of the plurality of plates includes a second coupling portion formed along an edge of the second plate and couplable with the first coupling portion. The first coupling portion includes an insertion protrusion. The second coupling portion includes: an accommodating portion forming an accommodating groove in which the insertion protrusion is inserted; and a catching portion configured to prevent the insertion protrusion from departing from the accommodating groove; and an inner rib protruding from an inner surface of the accommodating portion to be inserted in the insertion groove.
