<p>PROBLEM TO BE SOLVED: To enable to switch the detaching or attaching function of a suction panel to a detachable or attachable section or non-detachable section or non- attachable section. SOLUTION: A rail for mounting a slide knob is provided on a front flat surface having protruding guide ribs for rotating to switch a suction panel at both front surface sides in a front surface frame. A chevron-shaped or inverted L-shaped protruding rib 6a is so provided on the front surface as to smoothly conduct the sliding operation on the rail of the front surface frame, and a slide knob fixing rib is so provided in the front surface frame as to make it possible to set the upper end of the rib 6a to the lower end position of the rib of the front surface frame, thereby making it possible to also use it as the mounting guide of the suction panel. The upper end of the slide knob is so formed in a U-shape 6c as to guard the slide arm of the suction panel, and further performed by providing the lower side of the shape 6c in an oblique shape 6c.</p> |
