流れを示している。2. Description of the Related Art As a truck of a type in which cargo is stored and transported in a closed container, a truck equipped with a rectangular parallelepiped box-shaped panel van 7 as shown in FIGS. 11 and 12 is widely used. Such a box-type panel van 7 is usually set to a height that is as high as is allowed from various regulation values in order to maximize the loading capacity. Therefore, between the upper surface position of the roof panel 3 of the truck cabin 6 and the upper surface portion 7a of the box-shaped panel van 7 which is determined from the operating conditions, a large vertical width as shown by arrows in FIGS. The surface part 7b is generated. When the vehicle travels in such a state, the traveling resistance coefficient of the vertical surface portion 7b due to air in the vehicle traveling direction becomes a very large value, the fuel consumption rate of the truck increases, and the economic burden on the user and the environmental burden on society are reduced. It will be big. In order to prevent such a disadvantage, an air deflector 4 as shown in FIGS.
Is rectified so as not to be directly exposed to the airflow during traveling, and the air resistance coefficient is reduced to reduce the fuel consumption rate. In particular, air resistance is approximately proportional to the square of the running speed, so with the development of the highway network, the air deflector has become almost indispensable for this kind of truck. Note that FIG.
It shows the ideal air flow expected of a large air deflector.

いる。[0003] Such an air deflector is attached after the vehicle is completed as a separate component from the truck cabin and as a structure whose attachment position can be adjusted. This is because it is virtually impossible to integrate the air deflector with the cabin roof and make it permanently fixed, because various kinds of vans having different dimensions are mounted on the same chassis of the truck. As a known technique relating to such an air deflector mounting structure, there is Japanese Patent Application Laid-Open No. 3-182885. In this known technique, as is apparent from FIG. 1, the angle of attack with respect to the traveling direction of a drag foiler (corresponding to the air deflector) can be adjusted in accordance with the height of the van, so that the same type is used. The air deflector can be easily and easily attached to the original truck chassis even if various different sized vans are attached.

点が生ずる。As described above, the air deflector is mounted as a part separate from the truck cabin and as a structure whose mounting position and the like can be adjusted after the vehicle is completed. For this reason, a gap has to be formed all around the air deflector. Of this gap, FIG.
As shown in FIG. 1 and FIG. 12, an air flow flows from the gap 4b in front of and below the air deflector 4 during traveling, and moves with an unstable vortex outside the gap 7c behind and above the air deflector 4 to move. The effect of reducing the air drag coefficient by the deflector is reduced. In order to avoid such inconvenience, if the gap 4b is made as small as possible, the air deflector 4 vibrates due to the running of the vehicle and interferes with the roof panel 3, generating abnormal noise, peeling off the paint on the roof panel 3,
Problems such as the occurrence of rust due to the peeling of the coating occur.

However, in this method, since the sealing member 8 is made of a hard material and is fixed to the roof panel 3 with bolts or the like, a severe relative displacement occurs between the sealing member 8 and the roof panel 3 during traveling. The seal structure described above has a problem that the seal member 8 itself is likely to be permanently deformed or broken, or the roof panel 3 is easily damaged, rusted or permanently deformed.

However, since the seal member is made of an elastic material, the seal member constantly and smoothly comes into contact with the curved surface shape of the front edge portion of the air deflector thus deformed and deformed. Therefore, the seal member ensures the seal holding,
By contributing to the reduction of the air drag coefficient of the air deflector, the fuel consumption rate is reduced, the economic disadvantage of the user is reduced, and the environmental load on society is also reduced. In addition, even when the air deflector interferes with the roof panel under unexpectedly bad driving conditions, the bottom of the seal member hits the front edge of the air deflector to prevent damage to the roof.

FIG. 1 is an external perspective view of the installation state of the air deflector 4 and the front seal structure of the air deflector 4 of the present embodiment. The air deflector 4 includes the roof panel 3 and the van 7
Is installed between the vertical surface portion 7b and the vertical surface portion 7b so as to rectify the airflow during traveling. Both sides of the air deflector 4 have a substantially triangular shape, and the upper surface is fluidly connected between the front edge 4a at the front end of the air deflector 4 and the upper surface 7a of the van 7 with a gentle curved surface. Is configured. As described above, the air deflector 4 cannot be integrally formed with the roof panel 3 and the van 7 due to the vehicle structural design, and a gap must be provided between the air deflector 4 and the roof panel 3 and the van 7. I can't. In order to avoid mutual interference due to the elastic deformation of the air deflector 4 and the roof panel 3 generated during traveling, the gap must have a certain value or more. On the other hand, as described above, this gap reduces the effect of reducing the air resistance coefficient by the air deflector 4 during traveling, particularly in the gap 4b in front of and below the air deflector 4. Therefore, in the present invention, the gap 4b is closed by the seal member 1.

る状態を示す模式断面図である。Since the seal member 1 is made of an elastic material such as synthetic rubber such as EPDM (ethylene / propylene rubber), natural rubber, or synthetic resin, the front edge 4a of the air deflector 4 is formed.
Can be fixed to the roof panel 3 with the double-sided tape 2 so as to be in contact with the entire length of the roof panel 3. During traveling, the front edge 4a of the air deflector 4 is elastically displaced relative to the roof panel 3, and the front edge 4a itself is also elastically deformed. However, since the sealing member 1 is made of an elastic material, the sealing member 1 always comes into contact with the curved surface shape of the front edge portion 4a which is displaced and deformed as described above. Further, the sealing member 1 is fixed to the roof panel 3 with a double-sided tape 2. Therefore, the seal member 1 simultaneously follows the shape of the roof panel 3 that is elastically deformed during traveling without difficulty. As described above, the seal member 1 reliably closes the gap 4b, and the air deflector 4 sufficiently exerts the effect of reducing the air resistance coefficient. FIG. 3 schematically shows such a state, in which the lip 1a of the seal member 1 keeps the contact smoothly according to the displacement of the air deflector 4, and the sectional shape of the seal member 1 as a whole is 5 shows that the vicinity of the front edge 4a is maintained in such a shape that the rectifying effect of the air deflector 4 is not lost. Further, the bottom surface 1b of the seal member 1 on the side fixed to the roof panel 3 protects the surface of the roof panel 3 when the front edge 4a of the air deflector 4 is lowered due to deformation vibration or the like. Therefore, the roof panel 3 is not damaged. FIG. 4 is an external perspective view showing a combined state of the air deflector 4 and the seal member 1 of the present embodiment, and FIG. 5 is a perspective view of the seal member 1 of FIG.
FIG. 6 is a schematic cross-sectional view showing a state in which the sealing member 1 and the air deflector 4 are combined to generate an air flow rectifying effect.

FIG. As described above, the seal member 1 is made of synthetic rubber or the like and has a cross-sectional shape having both a sealing action and a rectifying action as shown in FIG. 8, and this cross section is the same over the entire length of the sealing member 1. This seal member 1 can be easily manufactured into a straight rod shape by an extrusion molding method, and can be extremely easily mounted on the roof panel 3 with a double-sided tape 2 as an independent part at the time of truck shipment or after shipment. Can be firmly installed or replaced without processing or damage. Further, since the seal member 1 is made of an elastic material, the seal member 1 having the same kind of cross-sectional shape can be used in a combination of an air deflector of various dimensions and a roof panel without deteriorating the initial performance.
The longitudinal direction of the sealing member 1 can be easily adjusted to a predetermined length by cutting. FIG. 9 shows a state in which a mounting member group 5 for mounting the air deflector 4 is mounted on the roof panel 3 of the truck cabin 6, and a front edge 4 a of the air deflector 4 is provided.
The state where the seal member 1 is fixed on the roof panel 3 in the vicinity is shown. The figure also shows that the mounting member group 5 for mounting the air deflector 4 may be of various structures, but the sealing member 1 is provided in a predetermined shape without being affected by the structure of the mounting member group 5. It also shows that it can be easily fixed in position. FIG. 10 is a partial view showing an example of the relationship between the roof panel 3, the air deflector 4, and the mounting member group 5. The figure also shows that a gap must be created between the air deflector 4 and the roof panel 3 and that the air deflector 4 can move following the vibration deformation of the roof panel 3.

とが出来る。The present invention has the following remarkable effects. 1) A rod-shaped sealing member having an L-shaped cross section made of an elastic material such as synthetic rubber, natural rubber, or synthetic resin is attached to the roof panel so as to close the gap between the front edge of the air deflector and the roof panel. By adopting a configuration that sticks,
The air drag coefficient of the air deflector can be reduced, the original purpose of the air deflector can be achieved, and the fuel consumption rate can be reduced. Therefore, the economic disadvantage of the truck user can be reduced, and the social environmental load can be reduced. 2) As described above, the gap detrimental to the performance of the air deflector can be easily closed, so that the gap between the roof deflector and the roof panel can be sufficiently secured. Can be sufficiently prevented. Also, even if the air deflector interferes with the roof panel in unexpectedly bad driving conditions,
Since the bottom of the sealing member comes into contact with the front edge of the air deflector, damage to the roof panel can be prevented. 3) The sealing member can be manufactured at a low cost by a method such as extrusion of an elastic material such as rubber or resin, and can be manufactured as an independent part on a roof panel using, for example, a double-sided tape or the like at the time of factory shipment or shipment of a truck. Even later, the roof panel can be firmly newly installed or replaced without processing or damaging the roof panel. In addition, since the sealing member is made of an elastic material, the same type of cross-sectional shape sealing member can be used for the combination of the air deflector of various sizes and shapes and the roof panel without deteriorating the performance of the air deflector. The direction can be easily adjusted to a predetermined length by cutting. As described above, the production and attachment of the seal member can be performed extremely easily and at low cost.
