This will be described in more detail.

The aforementioned shelf support 40 and the fixing bracket 30 are provided symmetrically on both sides with the shelf 50 interposed therebetween. In addition, the angle adjusting device 60 is equally provided on both shelf supports 40 and fixing brackets 30, respectively.

In the vertical frame 20, a height adjustment groove is formed along the longitudinal direction, and a moving block is installed in the height adjustment groove. This movable block is fastened with a bolt penetrating the fixing bracket 30, and has a structure in which the fixing bracket 30 moves up or down or the position is fixed according to the degree of tightening of the bolt.

In the shelf support 40, each rear end 42 is rotatably coupled to the fixing bracket 30 within an angle set by the angle adjusting device 60, and the rear end 42 has polygonal coupling holes. (44) is formed. And, at the lower end of the support part 46 extending forward from the rear end part 42, the seating end 48 has a structure bent horizontally along the longitudinal direction.
