PROBLEM TO BE SOLVED: To easily hold and remove a grille at a specified angle by turning the grille. SOLUTION: A bearing part 4 comprises of a horizontal groove 4b which opens the front end of a front surface panel 5 and extends backward, and a tilted groove 4a which is connected to the rear end of the horizontal groove 4b, and of which the rear part is made lower. Then, when a grille 2 is attached, a spindle 3 is inserted from the opening of the horizontal groove 4b, and is slid to the rear end of the tilted groove 4a and is axially supported, and engaging parts 6, 7 are engaged by turning the grille 2. When the grille 2 is detached from the engaging parts 6, 7 and turned at a specified angle, the grille 2 is held by holding means 8a, 9a being provided on both sides of the grille 2 and the front surface panel 5. Then, the grille 2 is removed, the grille 2 is further turned upward, and at the same time, is slid from the tilted groove to the horizontal groove while turning the spindle, by moving means 2a, 5b being provided at the upper ends of the front surface panel 5 and the grille 2, and the grille 2 is removed from the opening. |
