  As described above, a plurality of fins are provided at the air outlet of the vehicle. The user can adjust the air volume and direction of the air blown from the air outlet by changing the angle and direction of each fin.

  However, in such a vehicle, since the air blown out from the air outlet is likely to hit locally for a long time, such as the face and body of the occupant, the occupant is uncomfortable. It may be possible to change the direction of the fins of the air outlet so that the air blown out from the air outlet does not hit the occupant. , Hitting the ears, cheeks, etc., giving passengers discomfort.

  It is also conceivable that the flow rate of air blown from the air outlet is reduced to reduce passenger discomfort, but comfort is maintained when the flow rate of air blown from the air outlet is reduced. It will disappear.

  In the configuration in which a plurality of fins are swung as described in the above-mentioned Patent Document 1, it is difficult to blow the air-conditioning air so that it spreads around, and it is sufficient to reduce the discomfort of the passengers. Not. In addition, with the configuration described in Patent Document 1, it is difficult to maintain comfort without reducing the flow rate of air blown from the air outlet.

  Moreover, since what was described in the said patent document 1 is assembled | attached on the manufacturing line of a vehicle manufacturer, it cannot be retrofitted to a vehicle after vehicle purchase.

  The present invention has been made in view of the above problems, and it is an object of the present invention to be able to be retrofitted to a vehicle and to reduce the discomfort of an occupant and maintain comfort.

  In order to achieve the above object, the invention described in claim 1 is provided with an attachment portion (25) for attachment to an air outlet (80) for blowing air into the vehicle compartment, and a passage (100) for passing air from the air outlet. To 400), and the passage is formed to guide the air from the air outlet in the peripheral direction of the passage forming member. It is characterized by that.

  According to such a structure, since the attachment part for attaching to the air blower outlet (80) which blows off air in a vehicle interior is provided, the user can retrofit to a vehicle easily. Moreover, it is provided with the passage formation member (13, 21-23, 30, 40) in which the passage (100-400) which lets air from an air blower outlet was formed, and a passage is a passage formation member. Therefore, the air-conditioning wind can be blown out so as to spread around the periphery, reducing the discomfort of the occupant and maintaining the comfort.
