As a result, the light emitted from the light source is reflected, absorbed, and diffused by the dirt adhering to the surface of the housing and the louver covered with the light opaque material, and the color is changed or becomes unclear. You can keep the color development constant without
Normally, it is difficult for the light to reach, so it does not illuminate any dirt adhering to the back of the air outlet, which is inconspicuous. Further, even if dirt is attached to the light emitting surface, the light emitting surface can be removed by wiping it from the inside of the vehicle compartment, so that clear light emission can be easily maintained. Further, the light source can be attached to any place of the housing, and the degree of freedom in designing the shape and layout of the air outlet is high.

The surface of the side facing the circulation portion is covered with a light-impermeable material, and the surface facing the vehicle interior on the downstream side in the blowing direction has a light-emitting surface that maintains the light-transmitting property. The surface on the upstream side in the blowout direction at the blowout port is covered with a light-impermeable material, and the surface facing the vehicle interior on the downstream side in the blowout direction has a light emitting surface that maintains the light transmittance.

Therefore, according to the fourth aspect of the present invention, the light supplied from the light source is first taken into the inside of the housing and transmitted from the housing to the louver housing via the first light transmitting portion, and then the second light is transmitted. By being transmitted from the louver housing to the swing louver through the light transmitting portion, the light is emitted from the housing, the louver housing, and the light emitting surface of the surface facing the passenger compartment on the downstream side in the blowing direction of the swing louver into the space including the passenger compartment. However, it is not discharged from the surface of the outlet of the housing facing the air circulation portion or the surface of the louver on the upstream side in the outlet direction.

From this, the light emitted from the light source is
Due to dirt adhering to the surface of this housing, louver housing and louver covered with the light opaque material,
Coloring can be kept constant without being changed or blurred due to reflection, absorption or diffusion, and it is difficult for light to reach normally, so dirt that is not conspicuous is not illuminated.

Further, even if dirt is attached to the light emitting surface, it can be removed by wiping it from the inside of the vehicle compartment, so that clear light emission can be easily maintained. In addition, the light source can be attached anywhere on the housing, and the flexibility of the shape and layout of the air outlet is high.
