流れを示している。2. Description of the Related Art As a truck of a type in which a load is stored in a closed container and transported, a truck provided with a rectangular parallelepiped box panel van 7 as shown in FIGS. 11 and 12 is widely used. In such a box-shaped panel van 7, it is customary to set the maximum height allowed by 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 are determined from the driving conditions, a vertical line having a large vertical width as shown by the arrows in FIGS. The surface portion 7b is generated. When the vehicle travels in such a state, the running resistance coefficient due to air in the vehicle running direction of the vertical surface portion 7b becomes a very large value, the fuel consumption rate of the truck increases, and the user's economic burden and social environmental load are increased. It will be big. In order to prevent such a disadvantage, the air deflector 4 as shown in FIGS. 11 and 12 is installed to install the vertical surface portion 7b.
Is rectified so that it is not directly exposed to the air flow during traveling, and the air resistance coefficient is reduced to reduce the fuel consumption rate. In particular, the air resistance is proportional to the square of the traveling speed, and with the development of the highway network, the air deflector is almost indispensable for this kind of truck. Note that FIG.
Shows the ideal air flow expected from such an air deflector.

いる。Such an air deflector is mounted after the completion of the vehicle as a component separate from the truck cabin and as a structure whose mounting position is adjustable. This is because it is virtually impossible to integrate the air deflector with the cabin roof and to permanently fix the vane because various vans having different sizes are mounted on the truck chassis having the same specifications. As a publicly known technique relating to such an air deflector mounting structure, there is JP-A-3-182885. In this known technique, as is apparent from FIG. 1, the angle of attack of a drag foiler (corresponding to the air deflector) with respect to the traveling direction can be adjusted in accordance with the height of the van, so that the same characteristics can be obtained. The air deflector can be attached easily and easily even if various vans of different sizes are attached to the original truck chassis.

点が生ずる。As described above, the air deflector is attached after the completion of the vehicle as a component separate from the truck cabin and as a structure in which the attachment position and the like can be adjusted. Therefore, there is no choice but to create a gap around the entire circumference of the air deflector. Of this gap,
As shown in FIG. 1 and FIG. 12, an air flow flows in through a gap 4b in the front lower part of the air deflector 4 at the time of traveling, and moves out of the gap 7c in the upper rear part of the air deflector 4 with an unstable vortex flow to generate The effect of reducing the air resistance 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 traveling of the vehicle or the like and interferes with the roof panel 3 to cause abnormal noise or peeling off the coating of the roof panel 3,
Problems such as rusting due to peeling of the coating occur.

However, in this method, since the seal member 8 is made of a hard material and is fixed to the roof panel 3 by bolts or the like, the front lower portion of the air deflector 4 in which a severe relative displacement occurs with the roof panel 3 during traveling. The above-mentioned sealing structure has a problem that the sealing member 8 itself is likely to be permanently deformed or damaged, or the roof panel 3 is secondarily damaged, rusted, or permanently deformed.

However, since the seal member is made of an elastic material, the seal member always comes into contact with the curved surface shape of the front edge portion of the air deflector which is displaced and deformed in this way. Therefore, the seal member ensures the seal retention and
By contributing to the reduction of the air resistance coefficient of the air deflector, the fuel consumption rate is reduced, the economic disadvantage of the user is reduced, and at the same time, the environmental load on society is also reduced. Further, even if the air deflector unexpectedly interferes with the roof panel under bad driving conditions, the bottom portion of the seal member contacts the front edge of the air deflector to prevent damage to the roof.

FIG. 1 is an external perspective view of the installed state of the air deflector 4 and the front seal structure of the air deflector 4 of this embodiment. The air deflector 4 includes a roof panel 3 and a van 7.
It is installed so as to rectify the air flow during traveling between the vertical surface portion 7b and the vertical surface portion 7b. Both side surfaces of the air deflector 4 have a substantially triangular shape, and the upper surface portion connects the front edge portion 4a at the front end of the air deflector 4 and the upper surface portion 7a of the bun 7 with a gentle curved surface in a hydrodynamic manner. Is configured. As described above, the air deflector 4 cannot be configured integrally with the roof panel 3 and the van 7 in terms of vehicle structure design, and a gap must be provided between the air deflector 4 and the roof panel 3 and van 7. I can't. In order to avoid mutual interference due to elastic deformation of the air deflector 4 and the roof panel 3 that occur during traveling, these gaps must have a certain size 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 below the front of 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.
It 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. Further, during traveling, the front edge portion 4a of the air deflector 4 is elastically displaced relative to the roof panel 3, and the front edge portion 4a itself is elastically deformed. However, since the seal member 1 is made of an elastic material, the seal member 1 is always in contact with the curved surface shape of the front edge portion 4a which is displaced and deformed in this way. Further, the seal member 1 is fixed to the roof panel 3 with the double-sided tape 2. Therefore, the seal member 1 simultaneously and reasonably follows the shape of the roof panel 3 that elastically deforms during traveling. As described above, the seal member 1 surely 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 is kept in contact with each other according to the displacement of the air deflector 4, and the cross-sectional shape of the seal member 1 as a whole. It is shown that the vicinity of the front edge portion 4a is maintained in such a shape that the rectifying effect of the air deflector 4 is not lost. Further, the bottom surface portion 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 portion 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 this embodiment, and FIG. 5 is a seal member 1 of FIG.
FIG. 6 is a partial view of the end portion of FIG. 6, and FIG. 6 is a schematic cross-sectional view showing a state in which the seal member 1 and the air deflector 4 are combined to generate a rectifying effect of the air flow.

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 seal member 1. The sealing 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 by the double-sided tape 2 as an independent component at the time of factory shipment of the truck or after the 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 cross-sectional shape can be applied to a combination of various sizes and shapes of the air deflector and the roof panel without impairing the initial performance.
Further, the longitudinal direction of the seal member 1 can be easily cut and adjusted to a predetermined length. In FIG. 9, a mounting member group 5 for mounting the air deflector 4 is mounted on the roof panel 3 of the truck cabin 6, and the front edge portion 4 a of the air deflector 4 is mounted.
The state which fixes the sealing member 1 on the roof panel 3 of the vicinity is shown. In the figure, various structures can be adopted as the mounting member group 5 for mounting the air deflector 4, but the seal member 1 is not affected by the structure of the mounting member group 5 and has a predetermined structure. 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 there is no choice but to create a gap between the air deflector 4 and the roof panel 3, and 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 seal member with an L-shaped cross section made of an elastic material such as synthetic rubber, natural rubber or synthetic resin is applied 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 fixed structure,
The air deflector's air resistance coefficient can be reduced to achieve the original purpose of the air deflector, and the fuel consumption rate can be reduced. Therefore, it is possible to reduce the economic disadvantage of the truck user and also reduce the social environmental load. 2) As described above, the gap that is harmful to the performance of the air deflector can be easily closed, so that the gap with the roof panel can be sufficiently secured, and the air deflector interferes with the roof panel due to vibration during traveling. Can be sufficiently prevented. In addition, even if the air deflector unexpectedly interferes with the roof panel under bad driving conditions,
Since the bottom portion of the seal member comes into contact with the front edge portion 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 manufacturing method such as extrusion of elastic material such as rubber or resin, and can be used as an independent component on the roof panel by, for example, double-sided tape at the time of factory shipment of the truck or shipping. Even afterwards, the roof panel can be installed or replaced firmly without processing or damaging the roof panel. In addition, since the seal member is made of an elastic material, the seal member with the same type of cross-section can be used even when combining air deflectors and roof panels of various sizes without impairing the performance of the air deflector. The direction can be easily cut and adjusted to a predetermined length. As described above, the manufacture and attachment of the seal member can be performed extremely easily and inexpensively.
