 That is, the ventilation path has a light shielding position ventilation path and a storage position ventilation path.

 Therefore, when the light shielding body is set to the light shielding position, air can be taken in from the occupant side using the air passage for the light shielding position. When the light-shielding body is in the storage position, the lower side force on the occupant side can also take in air by using the storage position air passage.

 As a result, the air passage can efficiently take in dust, smoke, etc. floating on the passenger side, regardless of whether the light shielding body is in the retracted position or the light shielding position.

 The air purifier may have any configuration as long as it cleans the air. For example, it may reduce or reduce the amount of odor, dust, smoke, fungus, pollen in the air, or increase the amount of negative ions.

[0006] According to the second invention, the ventilation passage for the storage position has in part a ceiling surface cooperative intake passage formed by cooperation with the vehicle compartment ceiling surface by setting the light shield to the storage position. is doing. And by setting the light shield to the retracted position, air is sent to the air purifier via the ceiling surface cooperative intake passage.

 Therefore, by rotating the light shielding body to the light shielding position force storing position, a ceiling surface cooperative intake passage is formed. Therefore, the ventilation path is switched from the light shielding position ventilation path to the storage position ventilation path by rotating the light shielding body from the light shielding position to the storage position.

[0007] According to the third invention, the light shielding position vent passage is located on the passenger side of the light shielding body at the light shielding position. The intake port for taking air into the light shielding body and the discharge port for discharging the air purified by the air purifier inside the light shielding body from the light shielding body to the occupant side. The storage position vent is formed by a ceiling surface cooperative intake passage formed by closing the light shield and the intake port being blocked by the vehicle compartment ceiling surface, and the discharge port by the vehicle compartment ceiling surface. It has a ceiling surface cooperative exhaust passage formed by being blocked. Further, the storage position ventilation passage is for the storage position where the ceiling position cooperating intake passage communicates with the lower surface of the light shielding body, and the ceiling position cooperating exhaust passage communicates with the lower surface of the light shielding body. And a discharge port.

 [0008] Therefore, when the light shielding body is set to the light shielding position, dust or smoke floating on the passenger side is taken from the intake port and sent to the air purifier, and the air purified by the air purifier is Discharge Loca Discharge to the passenger side.

 When the light shield is in the retracted position, the intake port and the discharge port are blocked by the ceiling of the passenger compartment. Thereby, a ceiling surface cooperative intake passage and a ceiling surface cooperative exhaust passage are formed. For this reason, dust, smoke, etc. floating on the occupant side are taken into the air inlet for the storage position that opens the occupant side at the storage position, and sent to the air cleaner. Then, the air purified by the air purifier is discharged to the occupant side from the storage position discharge locuser through the ceiling surface cooperative exhaust passage.

 According to the fourth invention, the light shield has a plate-like visor body and a mirror unit attached to the visor body. The air purifier is provided in a hollow part formed between the visor body and the mirror unit!

 Therefore, the air purifier can be easily provided in the light shielding body.

 [0010] According to the fifth invention, the light shield includes a plate-like visor body and a mirror unit provided in an opening window that penetrates the visor body in the plate thickness direction. An air purifier is provided in the mirror unit, and an air passage is formed in the mirror unit.

 Therefore, since both the air purifier and the air passage are provided on the mirror unit side, the positional relationship between the air purifier and the air passage can be easily designed. Brief Description of Drawings
