Then, as shown in FIG. 16, the wall portion 55 is formed so that the position of the upper end 551a of the front side wall portion 551 is higher than the position of the upper end 552a of the rear side wall portion 552. By changing the heights of the front side wall portion 551 and the rear side wall portion 552, the generation of abnormal noise due to the contact between the first opening 53 and the entire upper surface of the wall portion 55 is suppressed.

Further, a gap 56 having a predetermined distance L3 is provided between the rear side wall portion 552 of the second opening 54 and the lower surface of the base cover 10 (the lower surface around the first opening 53). Due to the gap 56, it is possible to suppress the generation of abnormal noise due to the contact between the periphery of the first opening 53 of the base cover 10 and the rear side wall portion 552 of the second opening 54 of the panel 30.

Further, a lower surface portion 30a and a rear surface portion 30b of the panel 30 are formed so as to cover the gap 56 from below to the rear of the gap 56. By forming the lower surface portion 30a and the rear surface portion 30b of the panel 30 so as to cover the gap 56, the light leaked from the gap is blocked by the lower surface portion 30a and the rear surface portion 30b, so that light leakage can be prevented.

Further, a slope portion 57 that is inclined rearward from the rear around the second opening 54 is provided. In other words, the lower surface portion 30a of the panel 30 is tilted downward. By providing the slope portion 57, it is possible to set the light radiated from the second opening 54 so that the light directed backward is directed downward to be indirect illumination.

The lighting component 51 includes an LED 58 (Light Emitting Diode) and a lens 59 (light guide body) that guides the light emitted from the LED 58 inside the lighting component 51. As shown in FIG. 16, the lighting component 51 includes an LED 58 (Light Emitting Diode). When the 51 is attached to the base cover 10, the lens 59 is arranged so as to be located below the LED 58. Then, at least a part of the lens 59 is arranged at a position where it overlaps with the first opening 53 in the height direction.

By arranging the lens 59 at a position where it overlaps with the first opening 53 in the height direction, it is possible to reduce the size in the height direction and eliminate the gap between the lighting component 51 and the first opening 53. , It is possible to suppress the amount of light leakage.

The diameter L1 of the first opening 53 is set to be larger than the diameter L2 of the second opening 54. By making the diameter L1 larger than the diameter L2, it is possible to easily set the irradiation range of the light from the first opening 53 to be narrowed by the second opening 54.
