る。(Problem to be solved by the invention) However, in the case of the former, if compressive force is applied only in the butt direction when the ducts are connected, the entire flat part of the lining member will come into contact with the air conditioning duct; When the lining member is pressed so as to shift in the direction of the connection plane, only the apex part of the square comes into contact with the air conditioning duct and the flat part becomes non-contact, and although the compression rate of the apex part is high, the overall contact is The area becomes smaller, and water leaks from the small contact area due to its osmotic pressure. On the other hand, in the case of the latter, even if the lining member is pressed so that the air conditioning duct is displaced in the connection plane direction, the entire curved part will come into contact with the air conditioning duct and the contact area can be increased. As a result of pressing, the compressibility must be reduced, and water leaks from the contact area.

である。 In other words, in the past, there was a problem that the contact area and compressibility could not be balanced, and because one of them was small, water leaked from the contact area and a sufficient sealing effect could not be achieved. .
そこで、この考案は、上述したようにライニン
グ部材の形状に起因する従来の問題点を解消し、
シール性を向上させることができる空調ダクトの
シール装置を提供することを課題としている。 Therefore, this invention solves the conventional problems caused by the shape of the lining member as described above,
An object of the present invention is to provide a sealing device for an air conditioning duct that can improve sealing performance.

したことにある。(Means for Solving the Problems) Therefore, the gist of this invention is to make the lining member made of an elastic material have a cross-sectional shape with a curved part protruding to one side, and to add a dorsal fin to this curved part. The lining member is provided along the longitudinal direction, and the lining member is compressed and interposed between the air conditioning ducts so that the curved surface portion of the lining member is brought into close contact with one of the air conditioning ducts.

することができるものである。(Function) Therefore, even if the lining member is pressed so that the air conditioning ducts are displaced in the direction of their connection planes to connect the air conditioning ducts, the dorsal fins will be compressed by pulling inward to the curved surface. The dorsal fin has a high compression ratio, and since the curved surface portions on both sides of the dorsal fin come into contact with the other air conditioning duct, the contact area is large, and therefore the above object can be achieved.

However, a cooling heat exchanger is housed in the second air conditioning duct 1b, and a heating heat exchanger is housed in the third air conditioning duct 1c. The sealing devices 2a and 2b have a lining member 4 between flanges 3a to 3d formed at opposite ends of the respective air conditioning ducts 1a to 1c.
a, 4b are interposed, and air conditioning ducts 1 on both sides
After fixing the air conditioning ducts 1a and 1c in a predetermined position in the vehicle interior, the central air conditioning duct 1c connects to the air conditioning ducts 1a and 1c on both sides.
Since the lining members 4a and 4b are inserted and installed between the air conditioning ducts 1a to 1c, they are pushed and compressed in the connecting plane direction and axial direction of the air conditioning ducts 1a to 1c.

The flat portion 5 and the curved surface portion 6 are formed by cutting at the cutting plane A at the center of the main body portion 8a, and cutting at the cutting plane B at the center of the connecting portion 8b. The dorsal fin 7 is formed by this. This material 8 is made by compressing and molding urethane or the like using a hot press, and a smooth skin layer 10 is formed on the surface of a bubble layer 9 in the center due to the heat during molding.
0 remain as they are on the upper and lower surfaces of the lining members 4a and 4b.

される。 As shown in FIG. 1b, for example, the flat portion 5 of the lining member 4a is
It is inserted into a groove 11 formed in the flange 3a of the flange 3a, and is bonded to the bottom surface of the groove 11 via an adhesive 12 made of, for example, double-sided tape. On the other hand, the curved surface part 6 of this lining member 4a is compressed by the pressing force in the butting direction as described above, and the dorsal fin 7 is pulled into the inside of the curved part 6, and this dorsal fin 7 is strongly pressed and the inside of the curved part 6 is compressed. The curved surface portions 6 on both sides of the dorsal fin 7 come into contact with the flange 3b of the air conditioning case 1b. in this case,
As mentioned above, the connection plane direction (vertical direction in the figure)
When the air conditioning duct 1b is moved, contact between the curved surface portions 6 on both sides is ensured by applying strong pressure to the dorsal fin 7.
