<P>PROBLEM TO BE SOLVED: To enhance flexibility by allowing use of a shelf board for B5 size in a bookshelf for A4 size. <P>SOLUTION: Groups of engagement holes 19 are formed in each side board 2 of the bookshelf in two backward and forward lines. Each shelf board 4 has backward and forward front turnup parts 11 and right and left side turnup parts 12, each bracket 15 is formed with a support piece 17 on which the side turnup part 12 is placed, and the shelf board 4 is positioned in the bracket 15 by a rising piece 17a formed in the support piece 17. A body part 16 of the bracket 15 is formed with a pair of engagement claws 18 in a state that the engagement claws 18 are displaced in the back-and-forth direction. When changing installation of the brackets 15 to the right and left side plates 2, the attitude of the bracket 15 changes into an attitude wherein one end 16b is positioned in the front and an attitude wherein the other end 16c is positioned in the front, so that the back-and-forth position of the shelf board 4 changes into a forward alignment state and a backward alignment state. <P>COPYRIGHT: (C)2012,JPO&INPIT |
