In the above, the shelf board support has a locking member formed with a hook portion engageable with the engagement hole at one end of the male screw portion, and a width larger than the width of the engagement hole screwed into the male screw portion. The shelf support member is attached to the opposing surface of each column by engaging the hook portion with the engagement hole of the support column and screwing the shelf support member into the male screw portion and tightening. It fixes and a shelf board is mounted in each said shelf receiving member.

(2) In the above item (1), the shelf has a side piece facing downward on the outer peripheral edge of the rectangular shelf main body, and the left and right side pieces are cut off at both side ends. An upward concave portion is formed between the two and the concave portion is fitted into the shelf receiving member from above to support the shelf board.

(3) In the above item (1) or (2), the hook portion includes an engaging protrusion extending in the vertical direction around the male screw portion, and the dimension between the upper and lower ends of the engaging protrusion is set. The vertical dimension of the engagement hole of the support is larger.

(4) In any one of the above items (1) to (3), the male screw portion and the hook portion of the locking member are formed in a flat shape having the same thickness.

According to the present invention, the following effects can be achieved.
(A) According to the first aspect of the present invention, the shelf board support is firmly fixed to the support column by screwing and tightening the shelf receiving member into the male thread portion of the locking member. The shelf board can be stably laid on the shelf receiving member without coming off.
In addition, since the locking member and the shelf receiving member are not exposed to be larger than the shelf plate or the support column, the display space of the upper and lower shelf plates can be increased, and the appearance is also improved.

(B) According to the second aspect of the present invention, both side end portions of the front and rear side pieces formed on the shelf board body are notched, and an upward concave portion is formed between the left and right side pieces. Since the shelf board is supported by being fitted to the member from above, the movement of the shelf board in the lateral direction is prevented and the shelf board is prevented from being detached.

(C) According to the invention described in claim 3, the locking structure of the locking member to the engagement hole is simple, and the hook is tilted and inserted into the engagement hole so that the vertical engagement is achieved. Since the protrusion can be engaged with the upper and lower opening edges of the engagement hole, the locking member can be securely attached to the support column.

(D) According to the invention described in claim 4, the locking member can be manufactured easily and inexpensively, since it is sufficient that the locking member is formed by integrally pressing the plate material and then threaded into the male screw portion.
