In addition, the fastening protrusion 135 of the guide panel 130 can be easily inserted into the fastening hole 145d of the case top 140, so that no foreign matter is generated due to force fitting, and the case top It is possible to prevent scratches from occurring on the inner surface of the second vertical portion 141 of 140 or the outer surface of the first vertical portion 131 of the guide panel 130 .

In addition, the assembled and fastened case top 140 and the guide panel 130 can be easily disassembled, and reassembly can be easily performed.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

131: the first vertical portion of the guide panel
135: fastening protrusion of guide panel
140: case top
141: second vertical part
143: second horizontal part
145: piercing part (145a, 145b: first and second piercing holes, 145c: piercing plate, 145d: fastening hole, 145e: bent end)
