Problems solved by technology
[0004] However, in the case of adopting the traveling air introduction mechanism disclosed in the above-mentioned patent document, since the cover body and the frame body that cover the rotation shaft portion of the damper are integrally formed, it is difficult to secure a large effective opening area of the frame body.
As a result, it is difficult to achieve both the prevention of foreign matter and the effective opening area of the frame.

Embodiment Construction
[0018] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
[0019] figure 1 A structure in which the travel air introduction mechanism 1 according to the embodiment of the present invention is mounted on the front of a vehicle such as an automobile is shown. In this vehicle front structure, the travel air introduction mechanism 1 is connected to the front of the radiator 2 by bolt fastening or the like. The radiator 2 is fixed to the front ends of the side members 3 and the lower frame 4 extending in the front-rear direction of the vehicle by welding or the like.
[0020] Such as Figures 1 to 5 As shown, the travel wind introduction mechanism 1 of the present embodiment is provided with: a frame body 5 forming a plurality of openings 5a for introducing travel wind; It is provided so as to be freely rotatable between the position where the opening is opened; the drive unit 7 and the link mechanism 8 as a ...

A traveling air introducing mechanism according to the present invention comprises: a frame body having an opening through which traveling air is introduced; and a plate-shaped air door which is arranged on the inner side of the frame body in a manner of freely rotating between a position where the opening is closed and a position where the opening is opened. The air door is provided with a plate-shaped main body part, a rotating shaft part formed on at least one end of the main body part, and a plate part arranged on the rotating shaft part in a manner of intersecting with the extending direction of the rotating shaft part, and an insertion hole allowing the rotating shaft part to be freely inserted in a rotating manner is formed in the inner circumferential surface of the frame body. The plate part is located between the inner peripheral surface of the frame body and the main body part, and has a size capable of covering the insertion hole from the side of the main body part. Therefore, the effective opening area of the frame body can be greatly ensured, and foreign matters can be prevented from being stuck on the rotating shaft part of the air door.
Description
technical field [0001] The present invention relates to a running air introduction mechanism of a vehicle or the like. Background technique [0002] Conventionally, in a vehicle such as an automobile, a travel wind introduction mechanism is provided at the front of the vehicle in order to be able to change the introduction state of the travel wind. [0003] The travel air introduction mechanism described in Japanese Patent Laid-Open Publication No. 2015-93666 (patent document) includes: a frame body; a plate-shaped damper rotatably provided inside the frame body; The damper is driven between the closed position and the closed position. In addition, in order to prevent foreign matter from being caught on the rotating shaft portion of the damper (that is, foreign matter caught in the gap between the rotating shaft and the bearing hole of the frame), a cover is provided to cover the rotating shaft portion. The cover and the frame are integrally formed. [0004] However, in t...
